Description

Per @martijnharing in #8 (2026-07-20), a credential format definition needs to specify at least:

  • Value of the credential format identifier
  • Content of the credential type field
  • Meaning of the path element and how it relates to specific fields in the credential / response
  • How value matching works
  • How the issuer identifier request applies
  • Format specific extensions (e.g. cryptographic algorithm values)
  • How the cryptographic binding parameter request applies
  • Structure of the response for this format
  • What the transaction data request means for this format
  • How the transaction transcript is included in the response

The extension point what credential formats must specify needs to be defined.
