Abstract

The Comprehensive Learner Record (CLR) Standard has been designed to create, transmit, and render an individual's set of achievements, as issued by multiple learning providers, in a machine-readable format that can be curated into verifiable digital records of achievement.

1. Overview

This section is non-normative.

1.1 Audiences

The target readers for this document are:

1.2 Document Set

The CLR Standard (Comprehensive Learner Record Standard) has several related documents and artifacts shown below. Together they make up the specification.

1.2.1 OpenAPI 3.0 Files

The Open API Specification (OAS) defines a standard, programming language-agnostic interface description for HTTP APIs, which allows both humans and computers to discover and understand the capabilities of a service without requiring access to source code, additional documentation, or inspection of network traffic. When properly defined via OpenAPI, a consumer can understand and interact with the remote service with a minimal amount of implementation logic. Similar to what interface descriptions have done for lower-level programming, the OpenAPI Specification removes guesswork in calling a service.

-- OpenAPI Specification

1.2.2 JSON-LD Context File

When two people communicate with one another, the conversation takes place in a shared environment, typically called "the context of the conversation". This shared context allows the individuals to use shortcut terms, like the first name of a mutual friend, to communicate more quickly but without losing accuracy. A context in JSON-LD works in the same way. It allows two applications to use shortcut terms to communicate with one another more efficiently, but without losing accuracy.

Simply speaking, a context is used to map terms to IRIs. Terms are case sensitive and any valid string that is not a reserved JSON-LD keyword can be used as a term.

-- JSON-LD 1.1

The context file is available at: https://purl.imsglobal.org/spec/clr/v2p0/context-2.0.1.json.

1.2.3 JSON Schema

All JSON Schema can be found in § E.2 JSON Schema. JSON Schema files for credentials and API schema verification are available online:

1.3 Conformance Statements

As well as sections marked as non-normative, all authoring guidelines, diagrams, examples, and notes in this specification are non-normative. Everything else in this specification is normative.

The key words MAY, MUST, MUST NOT, NOT RECOMMENDED, NOT REQUIRED, OPTIONAL, RECOMMENDED, REQUIRED, SHALL, SHALL NOT, SHOULD, and SHOULD NOT in this document are to be interpreted as described in [RFC2119].

An implementation of this specification that fails to implement a MUST/REQUIRED/SHALL requirement or fails to abide by a MUST NOT/SHALL NOT prohibition is considered nonconformant. SHOULD/SHOULD NOT/RECOMMENDED statements constitute a best practice. Ignoring a best practice does not violate conformance but a decision to disregard such guidance should be carefully considered. MAY/OPTIONAL statements indicate that implementers are entirely free to choose whether or not to implement the option.

The Conformance and Certification Guide for this specification may introduce greater normative constraints than those defined here for specific service or implementation categories.

1.4 Terminology

1.5 Conceptual Model

This conceptual model describes CLR concepts and the relationship between those concepts. The data model in appendix § B.4 Shared Credential Data Models below is the normative reference for the classes and properties that are used to implement the concepts.

The conceptual model is targeted for all § 1.1 Audiences, while the data model is targeted for Solution Architects and Product Developers.

In the diagram below, the concepts are shown in gray boxes (e.g. Associations). Please see § 1.4 Terminology for definitions of the concepts.

Starting with this version of the CLR Standard, a CLR is also a Verifiable Credential (VC) as defined by the Verifiable Credentials Data Model v1.1 specification. The diagram includes labels that show the relationships between VC terminology and CLR terminology (e.g. Publisher is identified by the VC "issuer").

2.2 Recent graduate wants to hold a copy of their own official transcript

Categories: Higher Ed, K12

Samuel is a recent graduate of Atlas University. They majored in Mechanical Engineering and received a BSE Degree. Samuel requests an official diploma and transcript issued by Atlas University to store in their VC-compatible Wallet. Samuel requests the transcript from the Registrar's Office. The Registrar issues the transcript as a CLR Verifiable Credential (CLR VC) and notifies Samuel to accept the CLR into their wallet. The CLR VC includes several Assertions including the BSE Degree and Course completions.

Goal of the Primary Actor: Samuel's goal is to hold their BSE Degree and transcript to share directly with employers or other institutions that require and need to verify their degree and/or transcript.

Preconditions for this Use Case

Flow of Events

  1. Samuel requests the credentials be issued by Atlas University.
  2. Atlas issues the credentials to a known wallet user Samuel has registered.
  3. Samuel receives a notification that a credential has been issued
  4. Samuel logs into his wallet and is prompted to accept the credential

Post-Conditions/Success Criteria

Points of Failure

Variations

The official transcript contains pointer data toward course-related metadata such as the syllabus.

2.3 Job applicant provides proof of degree and transcript to potential employer

Categories: Higher Ed, Employment

Samuel wants to apply for a job opening at ACME Company. The job description requires proof of a degree in Mechanical Engineering and prefers that candidates provide a complete transcript. ACME Company will accept a Verifiable Presentation as evidence to accompany the job application. Samuel holds a CLR that bundles together their BSE Degree assertion and the assertions recognizing courses completed with relevant evidence. Using their wallet, Samuel creates a Verifiable Presentation that includes the Transcript CLR and attaches the VP to their job application. Horace, in HR at ACME Company uses the VP proof to verify that the VP was not corrupted, and the VC proofs to verify that the data issued by Atlas University was not corrupted as a complete transcript of Samuel's achievements at the school.

Goal of the Primary Actor: Samuel wants to prove that they have met the degree requirements for a position.

Actors

Preconditions for this Use Case

Flow of Events

  1. Samuel receives a request from ACME Company to present their credentials.
  2. Samuel selects the CLR credential as responsive to the request.
  3. The wallet uses Samuel's cryptographic key information to sign a VP containing the CLR VC.
  4. The VP is transmitted to ACME Company in response to the request.
  5. ACME's verifier software verifies the authenticity of the CLR VC, and further unpacks the individual assertions, verifying each.
  6. The software presents the list of assertion credentials to Horace to review.
  7. Horace confirms that the issuer is as expected, all relevant credentials are valid, and that the degree assertion is present and meets expectations. He reviews the list of courses, competencies, and extracurriculars and finds that Samuel is a well-experienced candidate.

2.4 Job applicant provides proof of degree and specific courses/engagements from the CLR

Categories: Higher Ed, Employment

Monique wishes to apply for a job opening at CHEM pharmaceutical Company. The job description requires proof of a degree in Chemistry and successful completion of Organic Chemistry class. The student possesses their institutionally issued CLR, but wishes to submit only the Degree and the Organic Chemistry courses to the CHEM company. Using their wallet, Monique creates a CLR Verifiable Presentation that pulls the Attested Degree and Courses from their CLR transcript. Harry, in HR at CHEM Company uses the VP proof to verify that the VP was not corrupted, and the VC proofs to verify that the data issued by the institution was not corrupted. There is an indicator on the CLR to let Harry know 1) the publisher was the student, 2) the record asserted was not the entire institutional transcript, and 3) the authority behind the degree is the institution, but the authority behind the assessment in the course in the College of Arts and Sciences.

Goal of the Primary Actor: Monique wishes to apply for a job opening at CHEM pharmaceutical Company.

Actors

Preconditions for this Use Case

Flow of Events

  1. Monique applies using her institutionally issued CLR and a digital wallet to curate and share only the two required verifiable credentials in a VP
  2. HR verifies the VP proof to verify that the VP was not corrupted, and the VC proofs to verify that the data issued by the institution was not corrupted and see that the CLR's publisher was the student (self asserted) and the record being asserted is not the entire institutional transcript but proof of a degree and of a single course completion.

Post-Conditions/Success Criteria

2.5 Higher Ed Competency-Based Education

Categories: Higher Ed, Training Providers

As a learner, I would like recognition and verification of all the credentials I acquired within the certificate, micro-credential, or degree program I attended, covering both academic and experiential learning activities I was involved in. The credentials would include the set of skills I acquired related to the degree or the certificate program I completed, the learning experiences I completed, along with the assessments carried out during my learning. The work I created for those assessments, and results of the assessments with scale and success level information should be included as evidence of my learning and skills. These achievements should be transferable so that I can continue to add upon these in my lifelong learning and be accepted by employers as proof of employability.

Goal of the Primary Actor: Learner wants to have skills-enhanced credentials that specify assessment approaches - from their academic as well as extracurricular/experiential learning represented in their CLR so they can best represent their abilities.

Actors

Preconditions for this Use Case

Flow of Events

  1. Issuer designs, develops and launches degree and non-degree offerings based on market relevance and skills most sought by employers
  2. Issuer creates and issues skills-aligned digital badges (or OB assertions within CLR assertion) for targeted achievements within the aforementioned degree and non-degree offerings
  3. Learner receives and can share CLR, which includes all earned digital credentials and a full listing of market relevant skills for each

Post-Conditions/Success Criteria

Points of Failure

2.6 Issuer Asserting All Student Achievements Comprehensively as a CLR

Categories: Higher Ed, K12

As an Issuer, I need to make a single, bulk CLR assertion for a student's full academic record with my institution. This may include degree completion and any underlying or related credentials such as courses, certificates, competencies, etc.

Goal of the Primary Actor: Assert/confer a full record for a student who has completed their program of study. Full manifest, similar to final academic transcript but also including complementary achievements that don't appear on the transcript, such as badges, competencies and skills.

Actors

Preconditions for this Use Case

Flow of Events

  1. student completes program of study
  2. issuer assets all academic achievements for this learner via a comprehensive CLR assertion
  3. consuming system, such as LER, represents all achievements in comprehensive assertion in student's learner record
  4. student makes achievements in record discoverable/shares
  5. hiring managers with relevant needs discover student based on their comprehensive achievement data.

Post-Conditions/Success Criteria

Points of Failure

2.7 Issuer Asserting Partial Transcript at Intermediate Points in Learning Journey

Categories: Higher Ed, K12

As an Issuer that operates under a more traditional semester or term model, I need to make batch-level CLR assertions per student at the end of each semester/term to augment their record with their semester/term achievements. I will make similar assertions at the end of each semester/term until the student completes their program of study.

Goal of the Primary Actor: Update Learning and Employment Record in batches tied to my semester/term schedule.

Actors

Preconditions for this Use Case

Flow of Events

  1. Learner is enrolled in multiple courses and earns achievements within them (i.e., competency-level) and at their completion
  2. Issuer makes CLR assertion at the end of each semester/term for each learner - can consist of multiple levels of achievement including course completion and related/child achievements like certificates earned, competencies mastered
  3. Learner wallet system for a student receives semester/term assertion and displays achievements to the student

Post-Conditions/Success Criteria

Points of Failure

2.8 Issuer Asserting Student Up to Date Partial Transcript of Achievements as CLR on Request

Categories: Higher Ed, K12

As an Issuer that uses a non-standard enrollment or term approach, I need to assert student achievements individually to augment their record with timely achievement/credential data as they occur, without limiting myself to using other data models/specifications or requiring my school to engineer for multiple data models. I also prefer the robustness of the CLR data model to other alternatives.

Goal of the Primary Actor: Assert achievements individually using CLR data specification to incrementally update student wallets/LERs with their achievements and credentials as soon as they are earned or on student request. Students will not have to wait until the end of each semester or program completion for their CLR-based achievements to be represented and leverage them in pursuing career goals incrementally.

Example: a student in our Cybersecurity Bachelor's program may earn CISSP certification at program midpoint and be able to gain entry-level employment in the cyber field long before completing their full degree. Incremental assertion of achievements and credentials can help enable this.

Actors

Preconditions for this Use Case

Flow of Events

  1. Learner is enrolled in multiple courses and earns achievements within them (i.e., competency-level) and at their completion
  2. Issuer makes CLR assertion for each discrete achievement as they occur or as the student requests them
  3. Learner wallet system for a student receives semester/term assertion and displays achievements to the student

Points of Failure

2.9 Internal Organizational Staff Development and Promotion

Categories: Employment, Training Providers

As a staff member at an employer, such as a University, Pat would like recognition and verification of all the credentials they acquired within the certificate and micro-credential bearing professional development activities they have undertaken during their ten years as an employee. These include LinkedIn Learning courses, MOOCs, technical training programs like AWS Academy, and locally offered in-person training (e.g. Inclusive Hiring practices).

Goal of the Primary Actor: In pursuit of a promotion to a management position, Pat wants to submit evidence of professional growth that has occurred since graduating with their bachelor's degree 10 years ago. The job posting requires a “Masters degree or equivalent skills and experience” and Pat would like to claim qualification under the latter case.

Actors

Preconditions for this Use Case

Flow of Events

  1. Pat identifies relevant verifiable credentials from within the CLR, and packages them as a self-signed CLR
  2. Pat transmits the self-signed CLR to the hiring manager for review.
  3. Hiring Manager receives application materials and reviews self-signed CLR and credentials it contains
  4. University HR verifies credential claims prior to making a job offer

2.10 Upskilling with Higher Ed Professional/Continuing Education (via Georgia Tech - Matt Lisle)

Issue 2: This use case has not been reviewed and appears to be a functional duplicate of the above
Issue 3: This use case has not been categorized

Categories: @@@TBD

As a working professional, Jane wants to advance her career by earning a credential that proves that she has obtained specific skills.

Jane is an employee at Local Company. To increase her chances of gaining a promotion at work, she would like to earn the Advanced Problem Solving Certificate at Georgia Tech Professional Education. This certificate requires completing a series of 4 in-person courses at Georgia Tech, each of which takes approximately 2-3 days. Upon completion, Jane would like to present a printed certificate to her employer as proof of completion. She would also like to add digital micro-credentials to her digital wallet for each of the 4 short courses, and a digital credential that represents her completion of the entire 4-course program. Eventually, Jane could share her digital credentials with her employer and they would automatically be ingested into Local Company's talent management system as part of Jane's employee record. These digital records would also be verifiable and tamper-proof. However, Local Company's current systems still necessitate the printable certificate.

Goal of the Primary Actor: Jane wants to earn an Advanced Problem Solving Certificate in order to advance her career.

Actors

Preconditions for this Use Case

Flow of Events

  1. Jane completes course 1.
  2. Upon completion of the in-person course, a GTPE employee marks Jane as complete in the GTPE learning management system.
  3. The GTPE learning management system presents a deep link specific to Jane that allows her to claim the credential.
  4. Jane imports the course credential into her wallet.
  5. As Jane progresses through the courses, GTPE updates the credential with additional achievementCredentials.
  6. Jane's digital wallet checks for updates on the GTPE credential whenever JAnes views the credential. Her progress through the courses is pulled into the wallet from the updated credential.
  7. Upon completing 4 courses, the GTPE SIS issues the program certificate within the same CLR.
  8. Jane is also emailed a printable certificate (preferably in PDF format) with a unique serial number (or similar security).
  9. Jane presents the printed certificate to her employer
  10. Her employer manually records the certificate in Jane's employee record.
  11. Using her digital wallet, and shares some or all of her five digital credentials with her online network and future potential employers.

(The following steps occur in a future state when Local Company's internal HR systems can ingest digital credentials)

  1. Jane opens her digital wallet, and shares the program-level digital credential with her employer.
  2. The employer verifies the credentials and ingests them into Jane's employee record.
  3. When a promotion opportunity arises at Local Company, Jane is flagged as a qualified candidate due -- in part -- to her Advanced Problem Solving certificate.

Post-Conditions/Success Criteria

Points of Failure

Variations

3. Getting Started

This section is non-normative.

3.1 Implementation Guide

The Open Badges Implementation Guide v3.0 contains non-normative information on how to implement [OB-30] and [CLR-20]. The Guide includes getting started information, best practices, key terms, and other useful inforation.

3.2 Conformance and Certification

Comprehensive Learner Record Standard Conformance and Certification Guide v2.0 - Specifies the conformance tests and certification requirements for this specification.

4. CLR Standard Document Formats

ClrCredentials can be exchanged as documents as defined in this section, or using the CLR Standard API. Documents can be exchanged as a text file, as a web resource, or embedded in an image. The contents of a CLR document MUST meet the following criteria:

4.1 File Format

If the credential is signed using the § 7.2 JSON Web Token Proof Format (VC-JWT) the contents of the file MUST be the Compact JWS string formed as a result of signing the ClrCredential with VC-JWT. The file extension SHOULD be ".jws" or ".jwt".

If an embedded proof method is used instead, the contents of the file MUST be the JSON representation of the ClrCredential. The file extension SHOULD be ".json".

4.2 Web Resource

If the credential is signed using the § 7.2 JSON Web Token Proof Format (VC-JWT) the contents of the response MUST be the Compact JWS string formed as a result of signing the ClrCredential with VC-JWT. The Content-Type SHOULD be text/plain.

If an embedded proof method is used instead, the contents of the response MUST be the JSON representation of the ClrCredential. The Content-Type SHOULD be application/json or application/ld+json.

4.3 Image Format

Comprehensive Learner Records (CLRs) may be exchanged as image files with CLRs encoded within. This allows CLRs to be portable wherever image files may be stored or displayed.

"Baking" is the process of taking a ClrCredential and embedding it into the image, so that when a user displays the image on a page, software that is CLR-aware can automatically extract that ClrCredential data and perform the checks necessary to see if a person legitimately earned the achievements within the CLR. The image must be in either [PNG] or [SVG] format in order to support baking.

4.3.1 PNGs

4.3.1.1 Baking

An iTXt chunk should be inserted into the PNG with keyword clrcredential.

If the credential is signed using the § 7.2 JSON Web Token Proof Format (VC-JWT) the text value of the chunk MUST be the Compact JWS string formed as a result of signing the ClrCredential with VC-JWT. Compression MUST NOT be used.

Example 1: An example of creating a chunk with VC-JWT proof (assuming an iTXt constructor) 
var chunk = new iTXt({
  keyword: 'clrcredential',
  compression: 0,
  compressionMethod: 0,
  languageTag: '',
  translatedKeyword: '',
  text: 'header.payload.signature'
});

If an embedded proof method is used instead, the text value of the chunk MUST be the JSON representation of the ClrCredential. Compression MUST NOT be used.

Example 2: An example of creating a chunk with embedded proof (assuming an iTXt constructor) 
var chunk = new iTXt({
  keyword: 'clrcredential',
  compression: 0,
  compressionMethod: 0,
  languageTag: '',
  translatedKeyword: '',
  text: '{
          "@context": [
            "https://www.w3.org/ns/credentials/v2",
            "https://purl.imsglobal.org/spec/clr/v2p0/context-2.0.1.json",
            "https://purl.imsglobal.org/spec/ob/v3p0/context-3.0.3.json",
            "https://purl.imsglobal.org/spec/ob/v3p0/extensions.json"
          ],
          "id": "http://example.edu/credentials/3732",
          "type": ["VerifiableCredential", "ClrCredential"],
          "issuer": {
            "id": "https://example.edu/issuers/565049",
            "type": "Profile",
            "name": "Example University"
          },
          "validFrom": "2010-01-01T00:00:00Z",
          "credentialSubject": {
            "id": "did:example:ebfeb1f712ebc6f1c276e12ec21"
          },
          "proof": { }
        }'
});

An iTXt chunk with the keyword clrcredential MUST NOT appear in a PNG more than once. When baking an image that already contains credential data, the implementor may choose whether to pass the user an error or overwrite the existing chunk.

4.3.1.2 Extracting

Parse the PNG datastream until the first iTXt chunk is found with the keyword clrcredential. The rest of the stream can be safely discarded. The text portion of the iTXt chunck will either be the JSON representation of a § B.1.1 ClrCredential or the Compact JWS string that was the result of signing the ClrCredential with § 7.2 JSON Web Token Proof Format.

4.3.2 SVG

4.3.2.1 Baking

First, add an xmlns:clr attribute to the <svg> tag with the value "https://purl.imsglobal.org/clr/v2p0". Directly after the <svg> tag, add an <clr:credential> tag.

If the credential is signed using the § 7.2 JSON Web Token Proof Format (VC-JWT) add a verify attribute to the <clr:credential> tag. The value of verify attribute MUST be the Compact JWS string formed as a result of signing the ClrCredential with VC-JWT.

Example 3: An example of a well baked SVG with VC-JWT proof 
<?xml version="1.0" encoding="UTF-8"?>
<svg xmlns="http://www.w3.org/2000/svg"
  xmlns:clr="https://purl.imsglobal.org/clr/v2p0"
  viewBox="0 0 512 512">
  <clr:credential verify="header.payload.signature"></clr:credential>

  <!-- rest-of-image -->
</svg>

If an embedded proof method is used instead, omit the verify attribute, and the JSON representation of the ClrCredential MUST go into the body of the tag, wrapped in <![CDATA[...]]>.

Example 4: An example of a well baked SVG with embedded proof 
<?xml version="1.0" encoding="UTF-8"?>

  <!-- rest-of-image -->
</svg>

There MUST be only one <clr:credential> tag in an SVG. When baking an image that already contains ClrCredential data, the implementor may choose whether to pass the user an error or overwrite the existing tag.

4.3.2.2 Extracting

Parse the SVG until you reach the first <clr:credential> tag. The rest of the SVG data can safely be discarded.

5. CLR Standard API

CLRs can be exchanged using the API (application programming interface) defined here, or as documents.

This specification defines a RESTful API protocol to be implemented by applications serving in the roles of Client and Resource Server. The API uses OAuth 2.0 for authentication and granular resource-based permission scopes. Please see the Comprehensive Learner Record Standard Conformance and Certification Guide v2.0 for a list of which endpoints must be implemented for certification.

Note: Non-individual access

The API defined here is intended for Clients and servers that give individual users control over access to their resources. While system-to-system bulk transfers using OAuth 2.0 Client-Credentials Grant are expected to occur, it is out of scope for this version of the specification to define. Future versions of this specification may add explicit support for OAuth 2.0 Client-Credentials Grant.

In addition to the documentation in this section, there are OpenAPI files for the CLR Standard API in both JSON and YAML format:

5.1 Architecture

Diagram showing the major components of the Open Badges API
Figure 1 Diagram showing the major components of the Open Badges API

There are five key components to the API architecture.

User
This is the user that owns the resources (ClrCredentials) that are on the resource server. Also called a Resource Owner.
Web Browser
This is the web browser the user interacts with.
Client
This is the web application that interacts with the resource server on behalf of the user. Also called Consumer in the IMS Global Security Framework v1.1.
Authorization Server
This is a server that implements the OAuth 2.0 endpoints on behalf of the resource server. In many systems, the authorization server and the resource server are combined.
Resource Server
This is the server that has the protected resources (ClrCredentials). Also called Provider in the IMS Global Security Framework v1.1.

The role of each component during Registration, Obtaining Tokens, and Authenticating with Tokens are described below.

5.2 Secure REST Endpoints

These endpoints are used to exchange ClrCredentials and Profile information.

All secure endpoint requests MUST be made over secure TLS 1.2 or 1.3 protocol.

All of the Secure REST Endpoints are protected by OAuth 2.0 access tokens as described in § 6. CLR Standard API Security.

Scopes

Each endpoint requires an access token with a specific CLR Standard scope as shown below.

Operation Scope
getCredentials https://purl.imsglobal.org/spec/clr/v2p0/scope/credential.readonly - Permission to read ClrCredentials for the authenticated entity.
upsertCredential https://purl.imsglobal.org/spec/clr/v2p0/scope/credential.upsert - Permission to create or update ClrCredentials for the authenticated entity.
getProfile https://purl.imsglobal.org/spec/clr/v2p0/scope/profile.readonly - Permission to read the profile for the authenticated entity.
putProfile https://purl.imsglobal.org/spec/clr/v2p0/scope/profile.update - Permission to update the profile for the authenticated entity.

5.2.1 getCredentials

Get issued ClrCredentials from the resource server for the supplied parameters and access token.

Request

GET /ims/clr/v2p0/credentials?limit={limit}&offset={offset}&since={since}

Request header, path, and query parameters
Parameter Parameter Type Description Required
limit
(query)
 PositiveInteger The maximum number of ClrCredentials to return per page. Optional
offset
(query)
 NonNegativeInteger The index of the first ClrCredential to return. (zero indexed) Optional
since
(query)
 DateTime Only include ClrCredentials issued after this timestamp. Optional
Responses
Allowed response codes and content types
Status Code Content-Type Header Content Type Content Description Content Required
200 application/json GetClrCredentialsResponse The set of ClrCredentials that meet the request parameters. Paging applies to the total number of ClrCredentials in the response. Required
400 application/json Imsx_StatusInfo As defined in [rfc9110], indicating that the server cannot or will not process the request due to something that is perceived to be a client error. Required
401 application/json Imsx_StatusInfo As defined in [rfc9110], indicating that the request has not been applied because it lacks valid authentication credentials for the target resource. Required
403 application/json Imsx_StatusInfo As defined in [rfc9110], indicating that the server understood the request but refuses to fulfill it. The exact reason SHOULD be explained in the response payload. Required
405 application/json Imsx_StatusInfo As defined in [rfc9110], indicating that the server does not allow the method. Required
500 application/json Imsx_StatusInfo As defined in [rfc9110]. Implementations SHOULD avoid using this error code - use only if there is catastrophic error and there is not a more appropriate code. Required
DEFAULT application/json Imsx_StatusInfo The request was invalid or cannot be served. The exact error SHOULD be explained in the response payload. Required
Example 5: Sample getCredentials Request

5.2.2 upsertCredential

Create or replace a ClrCredential on the resource server, appending it to the list of credentials for the subject, or replacing an existing entry in that list. The resource server SHOULD use the credential equality and comparison algorithm to compare and determine initial equality. The response code makes clear whether the operation resulted in a replacement or an insertion.

Note
This specification does not dictate the behavior of Hosts in the cases where the submitted credential is older than or the same as the existing one according to the credential equality and comparison algorithm.

5.4 Paging

Pagination of getCredentials results is controlled by two query string parameters appended to the request. The response includes the following pagination headers.

Response Header Description Required
X-Total-Count: <total_count> The resource server MUST include an X-Total-Count response header if the total result count is known. If the total result count is not known, the total count header MUST be ommitted. Conditionally Required for 200 OK Response
Link: <pagination_links> The resource server MUST include a Link response header if the list of credentials in the response is incomplete; and MAY include the Link header if the response is complete. Conditionally Required for 200 OK Response

If present, the Link header MUST support all of the following link relations (rel values):

Relation Description
next The link relation for the immediate next page of results. This MUST appear when the current list response is incomplete.
last The link relation for the last page of results. This MUST always appear.
first The link relation for the first page of results. This MUST always appear.
prev The link relation for the immediate previous page of results. This MUST appear when the offset is greater than zero.

5.5 Retry Behavior

Resource Servers MAY implement a Retry-After header to indicate a period of time to wait before attempting the request again.

If no Retry-After header is present and the response is non-2XX, it is recommended to retry the request in 30 minutes for an additional two attempts. After which, it MAY be desirable to alert the user that there is an issue with the connection (e.g. perhaps they need to reauthenticate or manually trigger the request when they believe services are back up).

6. CLR Standard API Security

The CLR Stardard API endpoints must use the methods outlined in Section 4, "Securing Web Services" of the IMS Global Security Framework v1.1. Clients and servers that give individual users control over access to their resources MUST use the OAuth 2.0 Authorization Code Grant method. A partial list of examples are shown in the table below:

Example Grant Method to Use
A university system maintains an achievement hub that students and alumni can use to retrieve their personal extended transcript. One of the students is using a digital wallet to assemble a personal portfolio. The student uses the wallet application to get their extended transcript from the university system's achievement hub. The client is the wallet application and the server is the achievement hub. OAuth 2.0 Authorization Code Grant because the learner is accessing their own individual resources.
A learner has used a digital wallet to assemble a comprehensive record of their achievements. The learner uses the wallet application to "submit" their CLR to a potential employer. The client is the wallet application and the server is the employer's career tracking system.
Note: Non-individual access

The API defined here is intended for Clients and servers that give individual users control over access to their resources. While system-to-system bulk transfers using OAuth 2.0 Client-Credentials Grant are expected to occur, it is out of scope for this version of the specification to define. Future versions of this specification may add explicit support for OAuth 2.0 Client-Credentials Grant.

6.1 Using OAuth 2.0 Authorization Code Grant

In scenarios where the learner or another third party is the resource owner, there will not be a pre-established trust relationship. Therefore the client credentials approach is insufficient. Instead you MUST use of OAuth 2.0 Authorization Code Grant.

Making a secured CLR Standard API request using authorization code grant comprises three steps:

  1. § 6.1.1 ACG - Registration - Share configuration information between the client and the server.
  2. § 6.1.2 ACG - Obtaining Tokens - Obtain an authorization code using a choreography between the client, web browser, user, and authorization server. Then request an access token by sending a request, using the previously obtained authorization code, to the Access Token service endpoint.
  3. § 6.1.3 ACG - Authenticating with Tokens - Use the access token in the Authorization header of the API request

6.1.1 ACG - Registration

To get started, the client and authorization server must share the four pieces of information shown below. Clients and servers that implement the Authorization Code Grant (ACG) method of resource access MUST implement § 6.4 Dynamic Client Registration to share this information.

client_id
This is the public identifier for the communication exchange. Also called a Secret in the IMS Global Security Framework v1.1.
client_secret
This is the shared secret for the communication exchange. Also called a Secret in the IMS Global Security Framework v1.1.
List of Scopes
The list of scopes that identify the set of endpoints for which access permission is being requested.
OAuth 2.0 Access Token Service Endpoint
The endpoint from which the approved, requesting client can obtain an access token.

If the client and authorization server support Token Revocation, they should also share:

OAuth 2.0 Revocation Service Endpoint
The endpoint a client can use to revoke an access token.

6.1.2 ACG - Obtaining Tokens

Obtaining an access token using an authorization code has two steps:

Once obtained, the client can freely re-use the access token up until the token's expiry time, so that the client need not repeat steps of obtaining an authorization code and requesting an access token for every API request. Token refresh is also available (see § Token Refresh Request).

ACG - Authorization Request

After the client application is registered with the authorization server as described in § 6.4 Dynamic Client Registration, the client application then MAY initiate an authorization request as described in Section 4.2 of the IMS Global Security Framework v1.1 by redirecting the user to the authorizationUrl as declared in the resource server's Service Description Document (SDD).

In the OAuth 2.0 Security Best Practices document [OAUTH2-SBP] the use of Proof Key for Code Exchange (PKCE) [RFC7636] is recommended in order to (with the help of the authorization server) detect and prevent attempts to inject (replay) authorization codes into the authorization response. When using 1EdTech specifications, PKCE MUST be used to protect Authorization Code Grant based access. The PKCE has two stages:

  • First the client MUST supply a code_challenge and code_challenge_method in the request for an authorization code. The authorization server is responsible for associating the code_challenge with the issued authorization code.
  • Then the client MUST supply the code_verifier in the Access Token Request, and the authorization server verifies the code_verifier.

    • Parameter Name Type Description Required
    response_type String Value MUST be set to "code". Required
    client_id String The client application identifier. MUST be the client_id provided in the Dynamic Client Registration § Register with Authorization Server response. Required
    redirect_uri URL The client application's redirection endpoint. MUST match one of the redirect_uris in the § 6.1.1 ACG - Registration request. Although this is optional in the IMS Global Security Framework v1.1, it is REQUIRED by this specification. Required
    scope String The scope of the authorization request. The authorization server is responsible for validating the scopes identified in the request and the response MUST include a scope parameter which confirms this list or comprises a subset of the services requested. Required
    state String An opaque value used by the client application to maintain state between the request and callback. The authorization server includes this value when redirecting the web browser back to the client. This parameter MUST be used for preventing cross-site request forgery. Required
    code_challenge String This is BASE64URL-ENCODE(SHA256(ASCII(code_verifier))). Required
    code_challenge_method String This MUST have a value of "S256" to indicate the SHA256 code verifier transformation method is used. Required

    All of the authorization request parameters are encoded in the authorization request as query string parameters. The request MUST be made by redirecting the browser to the OAuth 2.0 Authorization endpoint. The request MUST use HTTPS with TLS 1.2 or 1.3 protocol.

    Example 15: Sample ACG authorization request (line breaks for clarity) 
    HTTP/1.1 302 Found
Location: https://auth.example.com/authorize?
    client_id=4ad36680810420ed
    &response_type=code
    &scope=https%3A%2F%2Fpurl.imsglobal.org%2Fspec%2Fclr%2Fv2p0%2Fscope%2Fcredential.readonly%20offline_access
    &redirect_uri=https%3A%2F%client.example.com%2FAuthorize
    &state=26357667-94df-4a14-bcb1-f55449ddd98d
    &code_challenge=XeDw66i9FLjn7XaecT_xaFyUWWfUub02Kw118n-jbEs
    &code_challenge_method=S256
    ACG - Authorization Response

    If the redirect_uri matches a known client_id, the authorization server SHOULD present a UI asking the user to authenticate themself and grant the access request. The authorization server SHOULD display the client_name, client_uri, logo_uri, tos_uri, and policy_uri collected during Dynamic Client Registration to the user to help them decide whether to grant the access request.

    If the user authorizes the client application to access their resources with the requested scopes, the authorization server MUST redirect the browser back to the redirect_uri with the code, scope, and state query string parameters.

    The Authorization Code MUST be used only once. A lifetime for the authorization code of 600 seconds (10 minutes) is RECOMMENDED. If an authorization code is used more than once, the authorization server MUST deny the request and SHOULD revoke (when possible) all tokens previously issued based on that authorization code. The authorization code is bound to the client identifier and redirection URI.

    Parameter Name Type Description Required
    code String The authorization code. Required
    scope String The authorized scope for the access request (this MAY be a subset of the scopes in the request). The value is a space delimited set of scopes. Required
    state String The opaque value supplied by the client to maintain state between the request and callback. Required
    Example 16: Sample ACG authorization response (line breaks for clarity) 
    HTTP/1.1 302 Found
Location https://client.example.com/Authorize?
    code=dcf95d196ae04d60aad7e19d18b9af755a7b593b680055158b8ad9c2975f0d86
    &scope=https%3A%2F%2Fpurl.imsglobal.org%2Fspec%2Fclr%2Fv2p0%2Fscope%2Fcredential.readonly%20offline_access
    &state=26357667-94df-4a14-bcb1-f55449ddd98d
    Authorization Error Response

    If the authorization server does not recognize the client applications's redirection endpoint from a prior connection with this client application, the authorization server SHOULD inform the user of the error and MUST NOT automatically redirect to the web browser to the invalid redirection URI.

    If the user denies the authorization request or if the request fails for reasons other than a missing or invalid redirection URI, the authorization server informs the client by adding the following parameters to the query component of the redirection URI.

    Parameter Name Type Description Required
    error AuthorizationError A single ASCII [RFC20] error code from the AuthorizationError vocabulary. Required
    error_description String Human-readable ASCII [RFC20] text providing additional information, used to assist the client developer in understanding the error that occurred. Values for the "error_description" parameter MUST NOT include characters outside the set %x20-21 / %x23-5B / %x5D-7E.
    error_uri URI A URI identifying a human-readable web page with information about the error, used to provide the client developer with additional information about the error. Values for the "error_uri" parameter MUST conform to the URI-reference syntax and thus MUST NOT include characters outside the set %x21 / %x23-5B / %x5D-7E.
    state String The opaque value supplied by the client to maintain state between the request and callback. Required
    Example 17: Sample authorization error response 
    HTTP/1.1 302 Found
Location: https://client.example.com/cb?error=access_denied&state=xyz
    ACG - Access Token Request

    With the supplied code, the client application SHOULD attempt to exchange the code for an access_token. The client application makes an authorization grant POST request to the tokenUrl as declared in the resource server's Discovery Document. The HTTP POST request MUST include a Basic authorization header with the client_id and client_secret provided in the registration response. The body of the token request MUST include the following form fields:

    Field Name Type Description Required
    grant_type String Value MUST be set to "authorization_code". Required
    code String The authorization code received from the authorization server. Required
    redirect_uri URL The client application's redirection endpoint. Required
    scope String The scope of the access request. Required
    code_verifier String The PKCE code verifier. Required
    Example 18: Sample ACG token request (line breaks for clarity) 
    POST /token HTTP/1.1
Host: auth.example.com
Authorization: Basic NDE2ZjI1YjhjMWQ5OThlODoxNWQ5MDA4NTk2NDdkZDlm
Content-Type: application/x-www-form-urlencoded

grant_type=authorization_code
    &code=7c7a73263ee14b2b48073d0615f286ec74f6636689046cb8dbede0b5e87a1338
    &redirect_uri=https%3A%2F%client.example.com%2FAuthorize
    &scope=https%3A%2F%2Fpurl.imsglobal.org%2Fspec%2Fclr%2Fv2p0%2Fscope%2Fcredential.readonly+offline_access
    &code_verifier=mYUQfKNgI1lSbY8EqtvNHLPzu0x%2FcVKO3fpWnX4VE5I%3D
    ACG - Access Token Response

    If the authorization server grants this request (see Section 5.1 in [RFC6749] for the detailed description), it returns HTTP 200 OK status code with content type "application/json" consisting of a JSON object containing the access token and its expiry lifetime (1EdTech recommends a default expiry lifetime of 3600 seconds, one hour, for access tokens), optionally a refresh token, and confirms the set of scopes supported by the access token:

    Property Name Type Description Required
    access_token String The access token issued by the authorization server. Required
    token_type String The type of the token issued. The case insensitive value MUST be "bearer". Required
    scope String The scope of the access token. This is a space-separated list of scopes. Required
    expires_in PositiveInteger The lifetime in seconds of the access token. For example, the value "3600" denotes that the access token will expire in one hour from the time the response was generated. 1EdTech recommends a default expiry lifetime of 3600 seconds, one hour, for access tokens. If omitted, the authorization server SHOULD provide the expiration time via other means or document the default value. Optional
    refresh_token String The refresh token, which can be used to obtain new access tokens using the same authorization grant as described in § Token Refresh Request. Optional
    Example 19: Sample ACG token response 
    HTTP/1.1 200 OK
Cache-Control: no-store, no-cache, max-age=0
Pragma: no-cache
Content-Type: application/json; charset=UTF-8

{
    "access_token": "863DF0B10F5D432EB2933C2A37CD3135A7BB7B07A68F65D92",
    "refresh_token": "tGzv3JOkF0XG5Qx2TlKWIA",
    "expires_in": 3600,
    "token_type": "Bearer",
    "scope": "https://purl.imsglobal.org/spec/clr/v2p0/scope/credential.readonly offline_access"
}
    Access Token Error Response

    The authorization server MAY decide not to issue an access token. This could be because the request scopes are invalid, the credentials from the client may be invalid, etc. In this case the authorization server MUST return an HTTP 400 Bad Request status code with content type "application/json" consisting of a JSON object describing the error in the response body. The properties used to describe the error are:

    Property Name Type Description Required
    error TokenError A single ASCII [RFC20] error code]. See Section 5.2 of [RFC6749]. Required
    error_description ASCIIString Human-readable ASCII [RFC20] text providing additional information, used to assist the client developer in understanding the error that occurred. Values for the "error_description" parameter MUST NOT include characters outside the set %x20-21 / %x23-5B / %x5D-7E. Optional
    error_uri URI A URI identifying a human-readable web page with information about the error, used to provide the client developer with additional information about the error. Values for the "error_uri" parameter MUST conform to the URI-reference syntax and thus MUST NOT include characters outside the set %x21 / %x23-5B / %x5D-7E. Optional
    Example 20: Sample access token error response 
    HTTP/1.1 400 Bad Request
Content-Type: application/json;charset=UTF-8
Cache-Control: no-store
Pragma: no-cache

{
    "error": "invalid_request"
}

6.1.3 ACG - Authenticating with Tokens

After obtaining an access_token and optionally a refresh_token using the method above, a client application MAY issue request that access resources controlled by the user on the resource server using the access_token in the HTTP Authorization header [RFC2617] with a Bearer Token [RFC6750]. For example, a "getCredentials" would look like this:

Example 21: Sample getCredentials request 
GET ims/clr/v2p0/credentials
Host: example.edu
Authorization: Bearer 863DF0B10F5D432EB2933C2A37CD3135A7BB7B07A68F65D92
Accept: application/ld+json

6.2 Token Refresh

The recommended value of the access token's expires_in attribute is 3600 i.e. one hour. This means that the validity of the access token expires one hour after the time it was issued.

When requesting an access token as part of the Authorization Code Grant process, an authorization server MAY return a 'Refresh Token'. The refresh token can be used to obtain an access token using the same authorization grant: this is described in Section 6 of [RFC6749]. The use of the Refresh Token avoids the choreography for obtaining the credentials to gain access to the authorization server.

An Authorization Server is NOT REQUIRED to support token refresh.

Token Refresh Request

If the access_token is expired or about to expire, and the client application received a refresh_token, the client application can use OAuth 2.0 Token Refresh to get a new access_token and refresh_token.

The client makes a refresh POST request to the token endpoint by adding the following parameters using the "application/x-www-form-urlencoded" format in the HTTP request entity-body:

Parameter Name Type Description Required
grant_type String Value MUST be set to "refresh_token". Required
refresh_token String The refresh token issued to the client. Required
scope String The scope of the access request. The requested scope MUST NOT include any scope not originally granted by the user, and if omitted is treated as equal to the scope originally granted by the user. Required
Example 22: Sample ACG token refresh request 
POST /token HTTP/1.1
Host: auth.example.com
Authorization: Basic czZCaGRSa3F0MzpnWDFmQmF0M2JW
Content-Type: application/x-www-form-urlencoded

grant_type=refresh_token&refresh_token=tGzv3JOkF0XG5Qx2TlKWIA&scope=https%3A%2F%2Fpurl.imsglobal.org%2Fspec%2Fclr%2Fv2p0%2Fscope%2credential.readonly

Token Refresh Response

If valid and authorized, the authorization server issues a new access token and optionally a new refresh token as described earlier in § ACG - Access Token Response. If the request failed verification or is invalid, the authorization server returns an error response as described earlier in § Access Token Error Response.

6.3 Token Revocation

There may be deployments in which revocation of an access token is useful. The Token Revocation process is based upon [RFC7009]. The client requests the revocation of a particular token by making an HTTP POST request (using TLS) to the token revocation endpoint URL. Note that [RFC7009] states that implementations MUST support the revocation of refresh tokens and SHOULD support the revocation of access tokens.

Token Revocation Request

The client constructs the request by including the following parameters using the "application/x-www-form-urlencoded" format in the HTTP request entity-body:

Parameter Name Type Description Required
token String The token that the client wants to get revoked. Required
token_type_hint String MUST be set to either "access_token" or "refresh_token". Required
Example 23: Sample token revocation request 
POST /revoke HTTP/1.1
Host: server.example.com
Authorization: Basic czZCaGRSa3F0MzpnWDFmQmF0M2JW
Content-Type: application/x-www-form-urlencoded

token=45ghiukldjahdnhzdauz&token_type_hint=refresh_token

Token Revocation Response

The authorization server responds with HTTP 200 OK status code if the token has been revoked successfully or if the client submitted an invalid token.

When the request for revocation is rejected, the authorization server returns an error response as described earlier in § Access Token Error Response with an error code of "unsupported_token_type".

6.4 Dynamic Client Registration

Clients and servers that implement the Authentication Code Grant (ACG) method of resource access MUST implement the OAuth 2.0 Dynamic Client Registration Protocol [RFC7591]. There are two steps in this process:

  1. Request the Service Description Document (SDD) from the resource server
  2. Register with the authorization server
Sequence diagram for registration when using ACG flow
Figure 3 Sequence diagram for dynamic client registration when using ACG flow

The client only needs to register a client_id with the authorization server once. Each user will use the same client_id when they request their own authorization code.

Request the Service Description Document

To start the registration process, the user supplies the client with the resource server's base URL. When presented with an unknown resource server the client MUST request the resource server's Service Description Document (SDD) as shown in § 5.3.1 getServiceDescription.

Upon receiving a SDD from a resource server, the client SHOULD respect the Cache-Control and Expires headers if present in the response and configure local cache to match the directives it declares. If directives include one of no-cache, no-store, the client SHOULD NOT cache the data for future interactions. If directives include max-age or if an Expires header is present, the client SHOULD cache the SDD data, if valid, up to the expiration indicated, either at the time indicated by the Expires header or max-age seconds from request time.

An Etag header MAY be offered with the SDD response. If so, after a resource's declared expiration, a client MAY include an If-None-Match header containing the value of the Etag to check if the resource is still fresh. If so the resource server may return a 304 Not Modified response status code, and a new Expires or Cache-Control header MAY be included, which the client SHOULD use to update the cache expiration.

Register with Authorization Server

With the Client Registration URL in hand (from the x-imssf-registrationUrl property of the SDD), the client SHOULD post a registration request to the authorization server. The registration request MUST comply with OAuth 2.0 Dynamic Client Registration Protocol [RFC7591]. The registration request MUST NOT require an Initial Access Token. Use of the 'Software Statement' is NOT RECOMMENDED. The client registration request is sent to the Client Registration URL. The request MUST be sent using HTTPS with TLS 1.2 or 1.3 protocol.

The properties of the JSON body MUST be implemented as described in the following table. All URLs MUST use HTTPS (e.g. https://example.com/logo.png) and all URLs MUST have the same hostname. All required properties MUST be present in the registration request in order for it to be accepted by the authorization server. Arrays MUST be used even when a single value is to be sent.

Name Type Description Required
client_name String The human-readable name of the client application. Required
client_uri URL A page that describes the client application. Required
logo_uri URL The logo of the client application. If present, the authorization server SHOULD display this image to the end-user during approval. The value of this field MUST point to a valid image file. Required
tos_uri URL The human-readable Terms of Service for the client application that describes a contractural relationship between the end-user and the client that the end-user accepts when authorizing the client. Required
policy_uri URL The human-readable Privacy Policy for the client application that describes how the deployment organization collects, uses, retains, and discloses personal data. Required
software_id String A unique idenfitier assigned by the client application developer or software published used by registration endpoints to identify the client application to be dynamically registered. As described in [rfc7591], it SHOULD remain the same for all instances of the client application software. Required
software_version String A version identifier string for the client application software identifies by software_id. The value of software_version SHOULD change on any update to the client application software identified by the same software_id. Required
redirect_uris URL[] Array of redirection URI strings for use in the OAuth 2.0 flow. Required
scope String In the registration request, this is a string containing a space-separated list of scope values that this client application may include when requesting access tokens. If omitted, the authorization server MAY register a client application with a default set of scopes. In the registration response, this is a list of scopes the authorization server supports.

The list of scopes that can be requested are described below:

https://purl.imsglobal.org/spec/clr/v2p0/scope/credential.readonly
Permission to read CLRs for the user on the resource server platform.
https://purl.imsglobal.org/spec/clr/v2p0/scope/credential.upsert
Permission to create or update CLRs for the user on the resource server platform.
https://purl.imsglobal.org/spec/clr/v2p0/scope/profile.readonly
Permission to read the profile for the user on the resource server platform.
https://purl.imsglobal.org/spec/clr/v2p0/scope/profile.update
Permission to update the profile for the user on the resource server platform.
offline_access
Permission to issue a refresh_token along with the access_token.
Required
token_endpoint_auth_method String String indicator of the requested authentication method for the token endpoint. In this specification only "client_secret_basic" is allowed:
  • "client_secret_basic": The client application uses the HTTP Basic authentication method as defined in OAuth 2.0.
If omitted, the default is "client_secret_basic". 		Optional
grant_types String[] Array of OAuth 2.0 grant type strings. In this specification only "authorization_code" and refresh_token" are allowed:
  • "authorization_code": The authorization code grant type defined in OAuth 2.0.
  • "refresh_token": The refresh token grant type defined in OAuth 2.0.
If omitted, the default behavior is that the client will use only the "authorization_code" grant type. 		Optional
response_types String[] Array of OAuth 2.0 response type strings. In this specification only "code" is allowed:
  • "code": The authorization code response type defined in OAuth 2.0.
If omitted, the default is that the client will use only the "code" response type. 		Optional
contacts String[] Array of strings representing ways to contact people responsible for this client, typically email addresses. The authorization server MAY make these contact addresses available to end-users for support requests for the client application. Privacy constraints MUST be supported as applicable. Optional
Example 24: Sample registration request

}

If the authorization server accepts the registration request, it will store the information provided in the request and respond HTTP 201 Created with a registration response that includes a set of client credentials for the client application to use when requesting access tokens. All the information provided by the client application MUST be returned to the client application, including modifications to the properties as the authorization server deems necessary. An example response looks like this:

Example 25: Sample registration response

error ASCIIString Human-readable ASCII text description of the error used for debugging. Optional

7. Proofs (Signatures)

This section describes mechanisms for ensuring the authenticity and integrity of CLR Standard documents and payloads. At least one proof mechanism, and the details necessary to evaluate that proof, MUST be expressed for a credential to be a verifiable credential; that is, to be verifiable.

7.1 Proof Formats

The proof formats included in this specification fall into two categories:

Note
The issuer MAY use multiple proofs. If multiple proofs are provided, the verifier MAY use any one proof to verify the credential.

A third category of proof format called Non-Signature Proof is not covered by this specification. This category includes proofs such as proof of work.

7.2 JSON Web Token Proof Format

This proof format relies on the well established JWT (JSON Web Token) [RFC7519] and JWS (JSON Web Signature) [RFC7515] specifications. A JSON Web Token Proof is a JWT signed and encoded as a Compact JWS string. The proof format is described in detail in [VC-JOSE-COSE], refered from Section 5.13 "Securing Mechanism Specifications" of Verifiable Credentials Data Model v2.0. That description allows several options which may inhibit interoperability. This specification limits the options while maintaining compatibility with [VC-DATA-MODEL-2.0] to help ensure interoperability.

Note
At the time of the completion of this specification, the JSON Web Token Proof Format of [VC-DATA-MODEL-2.0] was undergoing a revision process. [VC-JOSE-COSE] will collect and display the result of this revision. The modifications resulting from the incompatibility of the revision with what is contained in this document will be added in future revisions.

7.2.1 Terminology

Some of the terms used in this section include:

  • JWT - "JSON Web Token (JWT) is a compact, URL-safe means of representing claims to be transferred between two parties. The claims in a JWT are encoded as a JSON object that is used as the payload of a JSON Web Signature (JWS) structure or as the plaintext of a JSON Web Encryption (JWE) structure, enabling the claims to be digitally signed or integrity protected with a Message Authentication Code (MAC) and/or encrypted." [RFC7519]
  • JWS - "JSON Web Signature (JWS) represents content secured with digital signatures or Message Authentication Codes (MACs) using JSON-based data structures. Cryptographic algorithms and identifiers for use with this specification are described in the separate JSON Web Algorithms (JWA) specification and an IANA registry defined by that specification." [RFC7515]
  • JWK - "A JSON Web Key (JWK) is a JavaScript Object Notation (JSON) data structure that represents a cryptographic key." [RFC7517]
  • Compact JWS - "A compact representation of a JWS." [RFC7515]

7.2.2 Overview

A JWS is a signed JWT with three parts separated by period (".") characters. Each part contains a base64url-encoded value.

  • JOSE Header - Describes the cryptographic operations applied to the JWT and optionally, additional properties of the JWT. [RFC7515]
  • JWT Payload - The JSON object that will be signed. In this specification, the JWT Payload includes the ClrCredential.
  • JWS Signature - The computed signature of the JWT Payload.

The JOSE Header, JWT Payload, and JWS Signature are combined to form a Compact JWS. To transform a credential into a Compact JWS takes 4 steps:

  1. Create the JOSE Header, specifying the signing algorithm to use
  2. Create the JWT Payload from the credential to be signed
  3. Compute the signature of the JWT Payload
  4. Encode the resulting JWS as a Compact JWS

The resulting JWS proves that the issuer signed the JWT Payload turning the credential into a verifiable credential.

When using the JSON Web Token Proof Format, the proof property MAY be ommitted from the ClrCredential. If a Linked Data Proof is also provided, it MUST be created before the JSON Web Token Proof Format is created.

7.2.3 Create the JOSE Header

The JOSE Header is a JSON object with the following properties (also called JOSE Headers). Additional JOSE Headers are NOT allowed.

Property / JOSE Header Type Description Required?
alg String The signing algorithm MUST be "RS256" as a minimum as defined in [RFC7518]. Support for other algorithms is permitted but their use limits interoperability. Later versions of this specification MAY add OPTIONAL support for other algorithms. See Section 6.1 RSA Key of the IMS Global Security Framework v1.1. Required
kid URI A URI that can be dereferenced to an object of type JWK representing the public key used to verify the signature. If you do not include a kid property in the header, you MUST include the public key in the jwk property.
Be careful not to accidentally expose the JWK representation of a private key. See RFC7517 for examples of private key representations. The JWK MUST never contain "d".
 Optional
jwk JWK A JWK representing the public key used to verify the signature. If you do not include a jwk property in the header, you MUST include the kid property.
Be careful not to accidentally expose the JWK representation of a private key. See RFC7517 for examples of private key representations. The JWK MUST never contain "d".
 Optional
typ String If present, MUST be set to "JWT". Optional
Example 26: Sample JOSE Header with reference to a public key in a JWKS 
{
  "alg": "RS256",
  "kid": "https://example.edu/keys#key-1",
  "typ": "JWT"
}

7.2.4 Create the JWT Payload

If you are going to use both external and embedded proof formats, add the embedded proofs prior to creating the JWT Payload.

7.2.4.1 Sign Nested Credentials

A ClrCredential has nested verifiable credentials. The Verifiable Credentials Data Model v1.1 specification does not specify how to encode a JWT Payload when the credential has nested credentials (it does have an example of an encoded presentation with a nested credential). To help ensure interoperability, this specification defines how to encode the JWT Payload with nested credentials.

The JSON Web Token Proof for each nested credential MUST be created prior to creating the JWT Payload for the parent credential. Because the JSON Web Token Proof for each nested credential is a Compact JWS string rather than a JSON object, the data model for a ClrCredential with VC-JWT proof is ClrCredentialJwtPayload.

  1. Create a JSON object using the ClrCredentialJwtPayload data model.
  2. Copy all of the claims from the parent credential to the new JSON object except for the nested credentials.
  3. Process each nested credential:
    • If the nested credential is already signed with a JSON Web Token Proof, simply add the Compact JWS string to the new JSON object.
    • If the nested credential is not signed with a JSON Web Token Proof, sign it with a JSON Web Token Proof and add the resulting Compact JWS string to the new JSON object.
  4. Use the new JSON object to form the JWT Payload.
Example 27: Sample ClrCredential prior to signing the nested AchievementCredentials 
{
  ...
  "credentialSubject": {
    "verifiableCredential": [
      {
        "id": "assertion1",
        ...
      },
      {
        "id": "assertion2",
        ...
      }
    ]
  }
}
Example 28: Sample ClrCredential after signing the nested AchievementCredentials 
{
  ...
  "credentialSubject": {
    "verifiableCredential": [
      "header.payload.signature",
      "header.payload.signature"
    ]
  }
}
7.2.4.2 JWT Payload Format

The JWT Payload is the JSON object with the following properties (JWT Claims). Additional standard JWT Claims Names are allowed, but their relationship to the credential is not defined.

Property / Claim Name Type Description Required?
exp NumericDate The validUntil property of the ClrCredential. Required if the ClrCredential has an validUntil. Optional
iss URI The issuer.id property of the ClrCredential. Required
jti URI The id property of the ClrCredential. Required
nbf NumericDate The validFrom property of the ClrCredential. Required
sub URI The credentialSubject.id property of the ClrCredential. Required
vc ClrCredential The ClrCredential being signed. Required

7.2.5 Create the Proof

Note: Sign and Encode the JWS

1EdTech strongly recommends using an existing, stable library for this step.

This section uses the follow notations:

  • JOSE Header - denotes the JSON string representation of the JOSE Header.
  • JWT Payload - denotes the JSON string representation of the JWT Payload.
  • BASE64URL(OCTETS) - denotes the base64url encoding of OCTETS per [RFC7515].
  • UTF8(STRING) - denotes the octets of the UTF-8 [RFC3629] representation of STRING, where STRING is a sequence of Unicode [UNICODE] characters.
  • The concatenation of two values A and B is denoted as A || B.

The steps to sign and encode the credential as a Compact JWS are shown below:

  1. Encode the JOSE Header as BASE64URL(UTF8(JOSE Header)).
  2. Encode the JWT Payload as BASE64URL(JWT Payload).
  3. Concatenate the encoded JOSE Header and the encoded JSW Payload as A | "." | B.
  4. Calculate the JWS Signature for C as described in [RFC7515].
  5. Encode the signature as BASE64URL(JWS Signature).
  6. Concatenate C and E as C | "." | E.

The resulting string is the Compact JWS representation of the credential. The Compact JWS includes the credential AND acts as the proof for the credential.

7.2.6 Verify a ClrCredential

Verifiers that receive a ClrCredential in Compact JWS format MUST perform the following steps to verify the embedded credential.

  1. Base64url-decode the JOSE Header.

  2. If the header includes a kid property, Dereference the kid value to retrieve the public key JWK.

  3. If the header includes a jwk property, convert the jwk value into the public key JWK.

  4. Use the public key JWK to verify the signature as described in "Section 5.2 Message Signature or MAC Validation" of [RFC7515]. If the signature is not valid, the credential proof is not valid.

    Note: Verifying the JWS Signature

    1EdTech strongly recommends using an existing, stable library for this step.

  5. Base64url-decode the JWT Payload segment of the Compact JWS and parse it into a JSON object.

  6. Convert the value of the JWT Payload to a ClrCredential and continue with § 7.2.6.1 Verify a Credential VC-JWT Signature.

    Note
    Credentials created following Verifiable Credentials Data Model v1.1 ([VC-DATA-MODEL]) store the OpenBadgeCredential in the vc claim of the JWT Payload. In this case, the contents of the vc claim must be converted to an ClrCredential and continue with § 7.2.6.1 Verify a Credential VC-JWT Signature.
7.2.6.1 Verify a Credential VC-JWT Signature
  • The JSON object MUST have the iss claim, and the value MUST match the id of the issuer of the ClrCredentialJwtPayload object. If they do not match, the credential is not valid.
  • The JSON object MUST have the sub claim, and the value MUST match the id of the credentialSubject of the ClrCredentialJwtPayload object. If they do not match, the credential is not valid.
  • The JSON object MUST have the nbf claim, and the NumericDate value MUST be converted to a DateTime, and MUST equal the validFrom of the ClrCredentialJwtPayload object. If they do not match or if the validFrom has not yet occurred, the credential is not valid.
  • The JSON object MUST have the jti claim, and the value MUST match the id of the ClrCredentialJwtPayload object. If they do not match, the credential is not valid.
  • If the JSON object has the exp claim, the NumericDate MUST be converted to a DateTime, and MUST be used to set the value of the validUntil of the ClrCredentialJwtPayload object. If the credential has expired, the credential is not valid.
Note
Credentials created following Verifiable Credentials Data Model v1.1 ([VC-DATA-MODEL]) have different names for attributes used in this process. Concretely, they have issuanceDate and expirationDate instead of validFrom and validUntil, respectively

7.3 Linked Data Proof Format

This standard supports the Linked Data Proof format. In order to opt for this format you MUST use the Data Integrity EdDSA Cryptosuites v1.0 suite.

Note
Whenever possible, you should use a library or service to create and verify a Linked Data Proof.

7.3.1 Create the Proof

Perform these steps to attach a Linked Data Proof to the credential:

  1. Create an instance of Multikey as shown in Section 2.1.1 DataIntegrityProof of [VC-DI-EDDSA].
  2. Using the key material, sign the credential object as shown in Section 7.1 Proof Algothim of [DATA-INTEGRITY-SPEC] to produce a Proof as shown in Section 2.2.1 DataIntegrityProof of [VC-DI-EDDSA] with a proofPurpose of "assertionMethod".
  3. Add the resulting proof object to the credential proof property.

7.3.2 Verify a ClrCredential Linked Data Signature

Verify the Linked Data Proof signature as shown in Section 7.2 Proof Verification Algorthim of [DATA-INTEGRITY-SPEC].

7.4 Key Management

Issuers will need to manage asymmetric keys. The mechanisms by which keys are minted and distributed is outside the scope of this specification. See Section 6. Key Management of the IMS Global Security Framework v1.1.

7.5 Dereferencing the Public Key

All the proof formats in this specification, and all Digital Integrity proofs in general, require the verifier to "dereference" the public key from a URI. Dereferencing means using the URI to get the public key in JWK format. This specification allows the use of an HTTP URL (e.g. https://1edtech.org/keys/1) or a DID URL (e.g. did:key:123), but only requires HTTP URL support.

8. Verification and Validation

Verification is the process to determine whether a verifiable credential is an authentic and timely statement of the issuer or presenter respectively. This includes checking that: the credential conforms to the specification; the proof method is satisfied; and, if present, the status check succeeds. Verification of a credential does not imply evaluation of the truth of claims encoded in the credential.

Validation is the process of assuring the verifiable credential meets the needs of the verifier and other dependent stakeholders. Validating verifiable credentials is outside the scope of this specification.

Note
The 1EdTech Validator performs verification as described here.

8.1 ClrCredential Verification

This section applies to Verifiable Credentials with a type of "ClrCredential".

  1. Check that the ClrCredential conforms to the specification:

    • If the ClrCredential has a credentialSchema property, and the type of the CredentialSchema object is "1EdTechJsonSchemaValidator2019", check that the credential conforms to JSON Schema as shown in 1EdTech JSON Schema Validator 2019. If it does not, the credential does not conform to the specification.
    • Check that the credentialSubject is identified by an id and/or an identifier. If neither is present, the credential does not conform to the specification.
    Note
    ClrCredentials created following Verifiable Credentials Data Model v1.1 ([VC-DATA-MODEL]) have different names for attributes used in this process. Concretely, they have issuanceDate and expirationDate instead of validFrom and validUntil, respectively. The data model of these credentials and their corresponding JSON schemas, are described at § B.11 Verification Support Data Models and § B.9 Derived Types, respectively.

  2. Check that the proof method is satisfied:

    Note
    The ClrCredential may have a VC-JWT proof and one or more Linked Data proofs. In this case, the Linked Data proofs will be attached to the ClrCredential in the vc claim of the signed JWT Payload. You may accept any one proof for verification. You do not need to verify all the signatures.

  3. Refresh the ClrCredential:

    Note
    Refresh must be completed after checking the proof so that the verifier is not spoofed into receiving a refreshed ClrCredential from a bad actor.
    • If the refreshService property is present, and the type of the RefreshService object is "ImsCredentialRefresh", refresh the credential as shown in 1EdTech Credential Refresh Service and then repeat steps 1 and 2. If the refresh is not successful, continue the verification process using the original ClrCredential.
      Note
      Only perform Refresh once. That is, do not complete Refresh a second time even if the refreshed ClrCredential also has a refreshService defined.

  4. Check the status:

    • A Credential is revoked if the credentialStatus property is present, and the type of the CredentialStatus object is "1EdTechRevocationList", and if the ClrCredential has been revoked as shown in 1EdTech Revocation List Status Method.
    • If the current date and time is before the validFrom, the ClrCredential is not yet valid.
    • If the current date and time is after the validUntil, the ClrCredential is expired.
    Note
    ClrCredentials created following Verifiable Credentials Data Model v1.1 ([VC-DATA-MODEL]) have different names for attributes used in this process. Concretely, they have issuanceDate and expirationDate instead of validFrom and validUntil, respectively. The data model of these credentials and their corresponding JSON schemas, are described at § B.11 Verification Support Data Models and § B.9 Derived Types, respectively.

  5. Optionally verify the subject (recipient):

    Note
    This step is optional, but RECOMMENDED when the ClrCredential has been exchanged with the verifier as one of the § 4. CLR Standard Document Formats.
    • A ClrCredential is about a person called the recipient. The recipient is identified in the credentialSubject (see ClrSubject) by id and/or one or more identifier (see IdentityObject). The id or identifier value to use for verification must be shared with the verifier in an out-of-band process such as by email. This is called the known value.
    • To verify the recipient using a known id, simply compare the known id with the id in the ClrSubject. If they are equal then the recipient is verified.
    • To verify the recipient using a known identifier such as email address follow these steps shown in § 8.2 Verify the Recipient Using an Identifier. If you find a match then the recipient is verified.
    • If no match is found, the recipient is not verified.

  6. Verify nested verifiable credentials:

    • A ClrCredential usually contains nested verifiable credentials in the credentialSubject. A ClrCredential may also contain nested EndorsementCredentials. If the nested verifiable credential has a type of "AchievementCredential" or "OpenBadgeCredential", verify the nested credential as shown in section "OpenBadgeCredential Verification" of the Open Badges Specification v3.0. If the nested verifiable credential has a type of "EndorsementCredential", verify the nested credential as shown in section "EndorsementCredential Verification" of the Open Badges Specification v3.0.

If all the above steps pass, the ClrCredential may be treated as verified.

8.2 Verify the Recipient Using an Identifier

The known identifier MUST be a plaintext string value. The known identifier type MUST be one of the types in IdentifierTypeEnum or an extension type. For example, if the known identifier is an email address, the known identifier type is emailAddress.

The ClrCredential issuer may include multiple identifiers that can be used for verification. The verifier should compare the known identifier (e.g. known email address) with all the identifiers included by the issuer until a match is found.

  1. If identifier.identityType does not match the known identifier type, skip to the next identifier.
  2. If identifier.hashed is true, calculate the known identifier IdentityHash using the known identifier and the identifier.salt. If the known identifier IdentityHash matches the identifier.identityHash, the recipient is verified.
  3. If identifier.hashed is false, and if the known identifier matches the identifier.identityHash, the recipient is verified.

9. Credential equality and comparison algorithm

Credential equality and comparison is the process to determine whether a verifiable credential is semantically equivalent to another one.

A Host SHOULD treat a credential as the same as another when both the issuer id and the ClrCredential id are equal after unescaping of any percent encoded characters [RFC3986] followed by truncation of leading and trailing whitespace.

If the two credentials are equal according to the above, then the credential with the newer validFrom is the more up-to-date representation and could be interpreted as a replacement of the prior issued credential.

9.1 Examples

9.1.1 Equality

Credentials A and B are equal since they have the same id and the same issuer.id.

The credential C is the up-to-date representation because it has a more recent validFrom (2010-03-01T00:00:00Z).

10. Verifiable Credentials Extensions

The Verifiable Credentials Data Model v1.1 standard defines several types of extensions to enable "permissionless innovation". Conformant extensions are tracked in the Verifiable Credentials Extension Registry.

This standard references four VC Extensions:

Note
The 1EdTech extensions are designed to work with any verifiable credential and may be contributed to the [VC-EXTENSION-REGISTRY] in the future.

A. Serialization

The data model as described in Appendix § B. Data Models is the canonical structural representation of an Comprehensive Learner Record verifiable credential (ClrCredential). All serializations are representations of that data model in a specific format. This section specifies how the data model is realized in JSON-LD and plain JSON.

A.1 JSON

The data model can be encoded in Javascript Object Notation (JSON) [RFC8259] by mapping property types in the Data Model to JSON types as follows:

A.2 JSON-LD

[JSON-LD] is a JSON-based format used to serialize Linked Data. The syntax is designed to easily integrate into deployed systems already using JSON, and provides a smooth upgrade path from JSON to [JSON-LD]. It is primarily intended to be a way to use Linked Data in Web-based programming environments, to build interoperable Web services, and to store Linked Data in JSON-based storage engines.

Instances of the data model are encoded in [JSON-LD] in the same way they are encoded in JSON (Section § A.1 JSON), with the addition of the @context property. The JSON-LD context is described in detail in the [JSON-LD] specification and its use is elaborated on in Section § C. Extending and Profiling this Standard.

Multiple contexts MAY be used or combined to express any arbitrary information about verifiable credentials in idiomatic JSON. The JSON-LD context for all verifiable credentials, available at https://www.w3.org/ns/credentials/v2, is a static document that is never updated and can therefore be downloaded and cached client side. The associated vocabulary document for the Verifiable Credentials Data Model is available at https://www.w3.org/2018/credentials. The JSON-LD context for Comprehensive Learner Record verifiable credentials is available at https://purl.imsglobal.org/spec/clr/v2p0/context-2.0.1.json. The associated vocabulary document for the Comprehensive Learner Record Data Model is available at https://purl.imsglobal.org/spec/clr/v2p0/context/clr_v2p0.html. Comprehensive Learner Record verifiable credentials MUST be serialized with both JSON-LD contexts.

Note
Though this specification requires that a @context property be present, it is not required that the value of the @context property be processed using JSON-LD. This is to support processing using plain JSON libraries, such as those that might be used when the verifiable credential is encoded as a JWT. All libraries or processors MUST ensure that the order of the values in the @context property is what is expected for the specific application. Libraries or processors that support JSON-LD can process the @context property using full JSON-LD processing as expected.
Example 33: JSON-LD @context serialization 
"@context": [
  "https://www.w3.org/ns/credentials/v2",
  "https://purl.imsglobal.org/spec/clr/v2p0/context-2.0.1.json",
  "https://purl.imsglobal.org/spec/ob/v3p0/context-3.0.3.json"
]

A.2.1 Compacted document form

[JSON-LD11-API] defines a compaction process for [JSON-LD11] documents, applying a context to shorten several fields of the document. The purpose of compaction is making the document to be represented in a form that is tailored to the use of the JSON-LD document directly as JSON.

One of the transformations made by this compaction process is representing properties with only one value as string or maps, while properties with multiple values are represented as an array of strings or maps.

The JSON-LD binding for Comprehensive Learner Record verifiable credentials (ClrCredential) MAY use singular values compaction in some attributes in the data model, such they can be expressed as a string – when having only one value – or an array of strings – when having multiple values.

The properties that may be compacted are listed in the following table:

Class Property
Achievement type
AchievementCredential type
AchievementCredential credentialSchema
AchievementCredential proof
AchievementCredential termsOfUse
AchievementSubject type
Address type
Alignment type
ClrCredential type
ClrCredential credentialSchema

EndorsementSubject type
Evidence type
Profile type
Related type
Result type
ResultDescription type
RubricCriterionLevel type
VerifiableCredential type
VerifiableCredential proof
VerifiableCredential credentialSchema
VerifiableCredential termsOfUse
A.2.1.1 Schemas

When using the compacted document form, the resulting document MAY not pass canonical JSON Schema files. This MAY end up in an unsuccessful verification of the credential, specially when the CredentialSchema property is used. To solve this, JSON Schema files compatible with [JSON-LD11-API] compaction process are available online:

Implementations using CredentialSchema MAY rely on this JSON schema files as valid values.

B. Data Models

B.1 ClrCredential Data Models

The data models in this section are specific to Comprehensive Learner Record Standard v2.0.

B.1.1 ClrCredential

A ClrCredential is a CLR with all the properties needed to conform with a Verifiable Credential as defined in the [VC-DATA-MODEL-2.0].

Property Type Description Multiplicity
@context Context The value of the @context property MUST be an ordered set where the first three items are the URLs https://www.w3.org/ns/credentials/v2, https://purl.imsglobal.org/spec/clr/v2p0/context-2.0.1.json, https://purl.imsglobal.org/spec/ob/v3p0/context-3.0.3.json. [1..*]
type IRI The value of the type property MUST be an unordered set. One of the items MUST be the IRI VerifiableCredential, and one of the items MUST be the IRI ClrCredential. [1..*]
id URI Unambiguous reference to the credential. [1]
name String The name of the CLR. May be displayed by wallet user interfaces. [1]
description String Optional description of the CLR. May be displayed by wallet user interfaces. [0..1]
endorsement EndorsementCredential Allows endorsers to make specific claims about the ClrCredential, or any AssertionCredential, Achievement, or Profile referenced in the ClrCredential. These endorsements are signed with a Data Integrity proof format. [0..*]
endorsementJwt CompactJws Allows endorsers to make specific claims about the ClrCredential, or any AssertionCredential, Achievement, or Profile referenced in the ClrCredential. These endorsements are signed with the VC-JWT proof format. [0..*]
image Image Optional image representing the CLR. May be displayed by wallet user interfaces. If present, MUST represent a PNG or SVG image. MAY be a 'baked' image. [0..1]
partial Boolean True if CLR does not contain all the assertions known by the publisher for the learner at the time the CLR is issued. Useful if you are sending a small set of achievements in real time when they are achieved. If False or omitted, the CLR SHOULD be interpreted as containing all the assertions for the learner known by the publisher at the time of issue. [0..1]
credentialSubject ClrSubject The learner that is the subject of this CLR credential. [1]
awardedDate DateTimeZ Timestamp of when the credential was awarded. validFrom is used to determine the most recent version of a Credential in conjunction with issuer and id. Consequently, the only way to update a Credental is to update the validFrom, losing the date when the Credential was originally awarded. awardedDate is meant to keep this original date. [0..1]
issuer Profile A description of the individual, entity, or organization that issued the credential. [1]
validFrom DateTimeZ Timestamp of when the credential becomes valid. [1]
validUntil DateTimeZ If the credential has some notion of validity period, this indicates a timestamp when a credential should no longer be considered valid. After this time, the credential should be considered invalid. [0..1]
proof Proof If present, one or more embedded cryptographic proofs that can be used to detect tampering and verify the authorship of the credential. [0..*]
credentialSchema CredentialSchema The value of the credentialSchema property MUST be one or more data schemas that provide verifiers with enough information to determine if the provided data conforms to the provided schema. [0..*]
credentialStatus CredentialStatus The information in CredentialStatus is used to discover information about the current status of a verifiable credential, such as whether it is suspended or revoked. [0..1]
refreshService RefreshService The information in RefreshService is used to refresh the verifiable credential. [0..1]
termsOfUse TermsOfUse The value of the termsOfUse property tells the verifier what actions it is required to perform (an obligation), not allowed to perform (a prohibition), or allowed to perform (a permission) if it is to accept the verifiable credentia [0..*]
This class can be extended with additional properties.

invalid_request The request is missing a required parameter, includes an invalid parameter value, includes a parameter more than once, or is otherwise malformed.
unauthorized_client The client is not authorized to request an authorization code using this method.
access_denied The resource owner or authorization server denied the request.
unsupported_response_type The authorization server does not support obtaining an authorization code using this method.
invalid_scope The requested scope is invalid, unknown, or malformed.
server_error The authorization server encountered an unexpected condition that prevented it from fulfilling the request. (This error code is needed because a 500 Internal Server Error HTTP status code cannot be returned to the client via an HTTP redirect.)
temporarily_unavailable The authorization server is currently unable to handle the request due to a temporary overloading or maintenance of the server. (This error code is needed because a 503 Service Unavailable HTTP status code cannot be returned to the client via an HTTP redirect.)

B.7.2 RegistrationError Vocabulary

This is the set of ASCII error code strings that may be returned in response to a client registration request. See [RFC7591].

Term Description

invalid_client_metadata The value of one of the client metadata fields is invalid and the server has rejected this request. Note that an authorization server MAY choose to substitute a valid value for any requested parameter of a client's metadata.
invalid_software_statement The software statement presented is invalid. This MUST only be returned if a Software Statement has been supplied in the registration request. Use of a Software Statement is NOT RECOMMENDED.
unapproved_software_statement The software statement presented is not approved for use by this authorization server. This MUST only be returned if a Software Statement has been supplied in the registration request. Use of a Software Statement is NOT RECOMMENDED.

B.7.3 TokenError Vocabulary

Term Description
invalid_request The request is missing a required parameter, includes an unsupported parameter value (other than grant type), repeats a parameter, includes multiple credentials, utilizes more than one mechanism for authenticating the client, or is otherwise malformed.
invalid_client Client authentication failed (e.g., unknown client, no client authentication included, or unsupported authentication method). The authorization server MAY return an HTTP 401 (Unauthorized) status code to indicate which HTTP authentication schemes are supported. If the client attempted to authenticate via the "Authorization" request header field, the authorization server MUST respond with an HTTP 401 (Unauthorized) status code and include the "WWW-Authenticate" response header field matching the authentication scheme used by the client.
invalid_grant The provided authorization grant (e.g., authorization code, resource owner credentials) or refresh token is invalid, expired, revoked, does not match the redirection URI used in the authorization request, or was issued to another client.
unauthorized_client The authenticated client is not authorized to use this authorization grant type.
unsupported_grant_type The authorization grant type is not supported by the authorization server.
unsupported_token_type The authorization server does not support the revocation of the presented token type. That is, the client tried to revoke an access token on a server not supporting this feature.
invalid_scope The requested scope is invalid, unknown, malformed, or exceeds the scope granted by the resource owner.

C. Extending and Profiling this Standard

This standard can be extended in three ways:

Extensions SHOULD be presented to the Comprehensive Learner Record project group for review and socialization.

Extensions MUST NOT be required.

Extensions WILL NOT be tested during conformance testing.

This standard can also be profiled. In general, profiling is used to:

C.1 Extending the Data Model

A data model extension may add new classes to the Data Model and/or new properties to existing extensible classes. Extensible classes are identified by the phrase, "This class can be extended with additional properties" shown at the bottom of the table of properties. For example, the Alignment class is extensible.

The extension SHOULD be documented with the following artifacts:

To use the extension implementers MUST do the following:

C.2 Extending Enumerated Vocabularies

All extensible enumerated vocabularies may be extended with custom terms. Extensible vocabularies are identified by the phrase, "This enumeration can be extended with new, proprietary terms" shown at the bottom of the table of terms. For example, the AchivementType enumeration is extensible.

Extended terms MUST start with the prefix "ext:". For example, ext:MyTerm.

The extended terms SHOULD be documented with the following artifacts:

To use the extended vocabulary implementers MAY do the following:

C.3 Extending the API

An API extension may add new endpoints (with or without new scopes) to the CLR Standard API and/or new responses to the existing endpoints.

The extension SHOULD be documented with the following artifacts:

C.4 Profiles

Profiling is the process by which an 1EdTech specification is tailored to meet the requirements of a specific community: the community could be a reflection of a market sector, a geographic location, etc. An example of such a community is the Norwegian K-12/Schools for whom a profile of the 1EdTech OneRoster 1.2 specification has been created. The process of profiling starts with the corresponding base specification and defines a set of new constraints to make the subsequent modified specification better fit the requirements of the target community. Once the profile has been defined, the next step is to create the corresponding Conformance Test Systems and Certification process for that profile: these will be modified versions of the equivalents created for the base specification. It is recommended that profiling is undertaken within 1EdTech so that the 1EdTech model driven specification tools can be used.

A profile is the product produced by the process of specification Profiling. A Profile of a 1EdTech specification consists of a set of new constraints. In general a 1EdTech specification enables a wide range education and learning workflows, processes and practices. A profile is designed to establish and impose best practices for the target community. A profile MUST only increase constraints i.e. it MUST NOT relax constraints in the base specification. For example the multiplicity of a property in the data model MAY be changed from [1..] (required and permitting many) to [1..1] (required and only one) but MUST NOT become [0..] (optional and permitting many). The most common profiling changes include more strict data typing, changes to enumerations, vocabulary changes, prohibition of endpoints and creation of new endpoints. A profile could make use of the extension capabilties to extend the specification to support new features. The key objective of a rofile is to remove, wherever possible, interoperability uncertainty e.g. by removing optionality.

It is strongly recommended that a profile of this standard is undertaken either by, or with the close support, of 1EdTech. However, no matter who is responsible for creating the profile artefacts (documents, schemas, etc.), it is strongly recommended that 1EdTech specification tools are used. This will ensure that the artefacts are consistent with the base specifications and that useful support documentation is automatically produced e.g. creation of a document that summarises the differences between the base specification and the profile.

E.2.1.11 AchievementCredential

AchievementCredentials are representations of an awarded achievement, used to share information about a achievement belonging to one earner. Maps to a Verifiable Credential as defined in the [VC-DATA-MODEL-2.0]. As described in § 7. Proofs (Signatures), at least one proof mechanism, and the details necessary to evaluate that proof, MUST be expressed for a credential to be a verifiable credential. In the case of an embedded proof, the credential MUST append the proof in the proof property.

E.2.1.15 Criteria

Descriptive metadata about the achievements necessary to be recognized with an assertion of a particular achievement. This data is added to the Achievement class so that it may be rendered when the achievement assertion is displayed, instead of simply a link to human-readable criteria external to the achievement. Embedding criteria allows either enhancement of an external criteria page or increased portability and ease of use by allowing issuers to skip hosting the formerly-required external criteria page altogether. Criteria is used to allow would-be recipients to learn what is required of them to be recognized with an assertion of a particular achievement. It is also used after the assertion is awarded to a recipient to let those inspecting earned achievements know the general requirements that the recipients met in order to earn it.

Note
Implementations SHOULD provide, at least, one of the id or narrative fields.

E.2.1.18 Evidence

Descriptive metadata about evidence related to the achievement assertion. Each instance of the evidence class present in an assertion corresponds to one entity, though a single entry can describe a set of items collectively. There may be multiple evidence entries referenced from an assertion. The narrative property is also in scope of the assertion class to provide an overall description of the achievement related to the assertion in rich text. It is used here to provide a narrative of achievement of the specific entity described. If both the description and narrative properties are present, displayers can assume the narrative value goes into more detail and is not simply a recapitulation of description.

E.2.1.23 Profile

A Profile is a collection of information that describes the entity or organization using Open Badges. Issuers must be represented as Profiles, and endorsers, or other entities may also be represented using this vocabulary. Each Profile that represents an Issuer may be referenced in many BadgeClasses that it has defined. Anyone can create and host an Issuer file to start issuing Open Badges. Issuers may also serve as recipients of Open Badges, often identified within an Assertion by specific properties, like their url or contact email address.

E.2.1.43 AchievementCredentialv1p1

AchievementCredentials are representations of an awarded achievement, used to share information about a achievement belonging to one earner. Maps to a Verifiable Credential as defined in the [VC-DATA-MODEL]. As described in § 7. Proofs (Signatures), at least one proof mechanism, and the details necessary to evaluate that proof, MUST be expressed for a credential to be a verifiable credential. In the case of an embedded proof, the credential MUST append the proof in the proof property.

E.2.1.49 Profilev1p1

A Profile is a collection of information that describes the entity or organization using Open Badges. Issuers must be represented as Profiles, and endorsers, or other entities may also be represented using this vocabulary. Each Profile that represents an Issuer may be referenced in many BadgeClasses that it has defined. Anyone can create and host an Issuer file to start issuing Open Badges. Issuers may also serve as recipients of Open Badges, often identified within an Assertion by specific properties, like their url or contact email address.
