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

Core Profile Properties

Name	Type	Description
@context	string[]	REQUIRED. An ordered array of URLs. The array MUST start with https://www.w3.org/ns/credentials/v2, followed by https://originator-profile.org/ns/credentials/v1.
type	string[]	REQUIRED. It MUST be ["VerifiableCredential", "CoreProfile"].
issuer	string	REQUIRED. It MUST be the OP ID of the VC issuing organization.
credentialSubject	object	REQUIRED. A JSON-LD Node Object containing the following credentialSubject properties.

credentialSubject Properties

Name	Type	Description
id	string	REQUIRED. It MUST be the OP ID of the CP holding organization.
type	string	REQUIRED. It MUST be Core.
jwks	object	REQUIRED. It MUST be a JWK Set, which is the set of public keys of the CP-holding organizations.

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.
