Core Profile Data Model

Terminology​

For terms not explained in this document, please see Terminology.

  • Core Profile (CP)
  • Originator Profile (OP)
  • Originator Profile Identifier (OP ID)
  • OP VC Data Model Conforming Document (OP VC DM Compliance Document)
  • Profile Annotation (PA)

Core Profile (CP) Data Model​

The Core Profile MUST be an OP VC DM compliant document and includes the following properties:

Properties​

@context​

REQUIRED. An ordered array of URLs, which MUST start with https://www.w3.org/ns/credentials/v2, followed by https://originator-profile.org/ns/credentials/v1.

type​

REQUIRED. It MUST be ["VerifiableCredential", "CoreProfile"].

credentialSubject​

REQUIRED. JSON-LD Node Object

credentialSubject.id​

REQUIRED. It MUST be the OP ID of the CP holding organization.

credentialSubject.type​

REQUIRED. It MUST be Core.

credentialSubject.jwks​

REQUIRED. It MUST be a JWK Set, which is the set of public keys of the CP-holding organizations.

issuer​

REQUIRED. It MUST be the OP ID of the VC issuing organization.

Extensibility​

Issuers MUST NOT add properties to the Core Profile that are not defined in the OP VC Data Model and this document, and specification developers SHOULD strongly avoid adding properties to the Core Profile.

If you need to do this, consider extending and publishing the Web Media Profile or Profile Annotation.
