Abstract

The Competencies and Academic Standards Exchange (CASE) Service specification is the definition of how systems achieve the exchange of information about learning standards and/or competencies. The key aim is to replace the current ways of documenting a learning standard and competency, typically a PDF or HTML document, by one which is machine readable both syntactically and semantically. Further, using this new specification it will be possible to electronically exchange these definitions so that applications, systems and tools can readily access this data.

1. Introduction

The Competencies and Academic Standards Exchange (CASE) specification defines how systems exchange and manage information about learning standards and/or competencies in a consistent and referenceable way. The key aim is to replace the current ways of documenting and referencing learning standards and competencies, which are typically published as a PDF or HTML document intended to be read by humans, by one which is also machine readable both syntactically and semantically. This allows for "Common Alignments" for content and referenceable unique identifiers for use in certificates and transcripts. Further, using this new specification it will be possible to electronically exchange these definitions so that applications, systems and tools can readily access and manage this data. This includes LMSs, Assessment tools, Curriculum Management applications, certificate and competency based evaluation systems and any other tool, process or content that would need to align to or reference a competency or framework.

This document describes the JSON-LD document formats for CASE 1.0.

1.1 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", "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.

1.2 Document Set

The documents that make up this specification are:

2. JSON-LD Binding

Service Providers that support the CASE JSON-LD Binding provide [JSON-LD] documents for each of the data model classes listed here:

CFAssociationGrouping
CFConcept
CFDocument
CFItem
CFItemType
CFLicense
CFPackage
CFRubric

2.1 Context

This binding uses the @context property to map short-form aliases to the URIs required by CASE documents. The @context property is REQUIRED. The @context property MAY be a string (URL) or array of strings (URLs). The value if it is a single string, or the first value if it is an array of strings, MUST be the URL https://purl.imsglobal.org/spec/case/v1p0/context/imscasev1p0_context_v1p0.jsonld. This URL resolves to the @context described in 1EdTech Competencies and Academic Standards Exchange (CASE) Service Version 1.0: JSON-LD Context.

Example 1: Usage of the @context property

{
    "@context": "https://purl.imsglobal.org/spec/case/v1p0/context/imscasev1p0_context_v1p0.jsonld",
    "type": "CFAssociationGrouping",
    "uri": "https://sandbox.casenetwork.imsglobal.org/uri/19655fb6-7aaf-11ea-a525-0242ac1c0003",
    "identifier": "19655fb6-7aaf-11ea-a525-0242ac1c0003",
    "lastChangeDateTime": "2020-04-09T22:11:45+00:00",
    "title": "Peer Categories",
    "description": "The associations in this group are between peer items with a category"
}

2.2 @id

The CASE JSON-LD Context file maps the alias uri to the JSON-LD @id property.

The uri property is REQUIRED for all of the documents described below. The uri MUST be a URL and, when dereferenced, results in a document containing machine readable information about the uri (@id).

When uri is used as the @id, it must be a canonical URL that MUST NOT change when the CASE standard if revised (i.e. v1p1 or v2p0). It SHOULD NOT change if the host server changes (e.g. if the framework is mirrored on another server). The URL MUST return the CASE resource as valid JSON-LD (as defined by this binding document) when the Accept header indicates "application/ld+json" is wanted. The URL MAY return other content and other content-type when the Accept header does not indicate "application/ld+json" is wanted.

2.3 @type

The CASE JSON-LD Context file maps the alias type to the JSON-LD @type property. The type property is REQUIRED for all of the classes covered by this binding except AssociationLink. The property MAY be a single string (IRI) or an array of strings (IRIs). The value if it is a string, or first value if it is an array of strings, MUST be the name of the class as defined in the specification [CASE-10].

Example 4: Usage of the @type property

{
    "@context": "https://purl.imsglobal.org/spec/case/v1p0/context/imscasev1p0_context_v1p0.jsonld",
    "type": "CFAssociationGrouping",
    "uri": "https://sandbox.casenetwork.imsglobal.org/uri/19655fb6-7aaf-11ea-a525-0242ac1c0003",
    "identifier": "19655fb6-7aaf-11ea-a525-0242ac1c0003",
    "lastChangeDateTime": "2020-04-09T22:11:45+00:00",
    "title": "Peer Categories",
    "description": "The associations in this group are between peer items with a category"
}

2.4 Associations

Associations between CFDocuments and between CFItems MAY be included in the CFDocument and CFItem. The set of associations is represented by the associationSet property which is a set of AssociationLink class, not by the CFAssociation class defined in [CASE-INFO-10].

Because the associations between two CFItems may be included in both CFItems, this binding extends the allowable values of CFAssociationTypeEnum to include reciprical relationships.

2.4.1 associationSet Property

CFDocument and CFItem have a new property associationSet which is an array of AssociationLink objects.

2.4.2 AssociationLink Class

Property	Type	Definition
type	string	The JSON-LD `@type` "AssociationLink".
associationType	CFAssociationTypeEnum	The type of association. This uses an enumerated vocabulary.
identifier	UUID	An unambiguous, synthetic, globally unique identifier for the CFAssociation. This is the primary way in which the exchange identification is achieved.
uri	URL	The `uri` of the link target.
title	string	A human readable title for the associated object.

2.4.3 CFAssociationTypeEnum

Value	Description
exactMatchOf	Equivalent to. Used to connect derived CFItem to CFItem in original source CFDocument.
exemplar	The target of the association is an example of best practice for the definition of the item.
hasPart	The target of the association is included either physically or logically in the item.
hasPredecessor	The target of the association comes before the item.
hasSkillLevel	The target of the association is understood to define a given skill level i.e. Reading Lexile 100, Depth Knowledge 2, or Cognitive Level (Blooms Taxonomy).
isChildOf	To represent the structural relationship in a taxonomy between parent and child. The item is a child of the target of the association.
isParentOf	To represent the structural relationship in a taxonomy between parent and child. The item is a parent of the target of the association.
isPartOf	The item is included either physically or logically in the target of the association.
isPeerOf	The item is a peer of the target of the association.
isRelatedTo	The item is related to the target of the association in some way that is not better described by another association type.
precedes	The item comes before the target of the association in time or order.
replacedBy	The item has been supplanted by, displaced by, or superseded by the target of the association.
replaces	The item supplants, displaces, or supersedes the target of the association.
skillLevelFor	The item is understood to define a given skill level i.e. Reading Lexile 100, Depth Knowledge 2, or Cognitive Level (Blooms Taxonomy) for the target of the association.

2.5 CFPackage

The base CFPackage class does not have a uri property to act as the JSON-LD @id. Therefore this binding adds a new uri property to CFPackage with all the same attributes described in @id.

note

The CFPackage uri must be different than the CFDocument uri.

3. Extending the Binding

In addition to the standard properties for CFSubject, the [JSON-LD] document includes the @context and type properties.

Example 13: CFSubject

{
    "@context": "https://purl.imsglobal.org/spec/case/v1p0/context/imscasev1p0_context_v1p0.jsonld",
    "type": "CFSubject",

B. Revision History

B.1 Version History

Version No.	Release Date	Comments
1EdTech Candidate Final Release 1.0	May 19, 2021	Based on member feedback the following changes were made: `@context` and `type` can be a single string or an array of strings. Allow additional properties in the JSON-LD documents. Use the existing `uri` property as the `@id` where available (i.e. all but CFPackage) Removed section on Internal Links since LinkURI no longer needs a `targetId` property. Renamed the `targetId` property of AssociationLink to `uri`. Relaxed constraint on AssociationLink `uri` property so that the JSON-LD representation of a CFItem can be associated with an external CFItem on a provider that does not support JSON-LD. Extended the allowable values for CFAssociationTypeEnum to include reciprical values. Add CFSubject sample.
1EdTech Candidate Final Release 1.0	August 28, 2020	Based on member and invited expert feedback the following changes were made: Removed AssociationSet class and rewrote the Associations section. Defined `targetId` and `uri` as `@id` properties in the @context file [CASE-CONTEXT-10] `"targetId": { "@id": "case:targetId", "@type": "@id" }, "uri": { "@id": "case:uri", "@type": "@id" }` Added optional `type` property to all JSON Schema definitions Updated all the examples to include `type`
1EdTech Candidate Final Release 1.0	June 18, 2020	First release of the JSON-LD Binding for CASE Version 1.0.
