20    "tag": "external-identifier",
21    "persist": true

When persist is set to true, both the credential and the credential meta-data will be held in the Registry.

When persist is set to false, only the following meta-data will be stored:

  • id

  • tag

  • credentialStatus (in the case of Revocation)

  • issuanceDate

For credentials issued using the OIDC flow, the persist attribute will be false.

The optional tag attribute can be used to reference the issued credential using a value of any string up to 1024 characters. By setting the tag to an external identifier, it gets stored in the credential meta-data and it can be used to Search for a Credential in the Registry.
