Details

Endpoint: /createCredential
(no new endpoint - this endpoint is implemented via #7 )

Credential Schema:

{
    "id": "uuid",
    "@context": [
        "https://www.w3.org/2018/credentials/v1",
        "https://w3id.org/catenax/credentials/v1.0.0"
        ],
    "type": ["VerifiableCredential", "BpnCredential"],
    "issuanceDate": "{creation date - format: 2022-06-16T18:56:59Z}",
    "expirationDate": "{expiration date - format: 2022-06-16T18:56:59Z}",
    "issuer": "{did issuer}",
    "credentialSubject": {
        "id": "{did holder}",
        "holderIdentifier": "{bpn}",
        "bpn": "{bpn}",
    }
}

Explanation:

• id is the uuid of the newly created credential - the uuid is defined by the issuer component
• context is fix defined for the current used schema - we should already consider that the schema might get updated in future ideally we are flexible to have this scenario that the old schema is set to "INACTIVE" and a new schema is used for new created credentials
• type is fix defined for this specific credential
• issuanceDate calculated on runtime
• expirationDate calculated by the issuer component based on defined credential static data expiry date => always not > 12 month
• issuer holds the issuer did
• credentialSubject
  • id holds the customer/holder did
  • holderidentifier BPN number of the holder
  • bpn BPN number provided via POST Endpoint
