Agenda

Open Issue

  • Issue 102: AnonCreds object signed by the key of the publisher
    • Which is related to Issue 74: issuer_did and schema_issuer_did should be IDs?
  • Latest on the AnonCreds W3C Verifiable Credentials Data Model Standard
    • Is it wrong to format an AnonCreds credential in the W3C Format?
  • Any update on what "prover_did" is used for during AnonCreds processing.  Notably, does the value require any special characteristics when it is used in the AnonCreds code?
    • Any insight on why it was added in the first place?
    • If we were to deprecate it as an input, would we need to use something else to replace it in the AnonCreds code?
  • Help with dependabot pull request: 113
  • Checkin: anoncreds-rs implementation progress, requests
  • Open Discussion

Future Calls

To Dos:

  • Issue to be added and further investigation into what happens to the nonce(s) by Belsy.
  • Updates to the spec. re: revocation data model, prover_did and nonces uses
  • Backwards Compatibility
    • PRs in (#82, #105) that seem to change public data structures – ones that are handled outside of AnonCreds and/or by two or more participants (issuer, holder, verifier)
    • We want to retain compatibility with existing data – credentials that have been issued and the published AnonCreds objects on which they rely.
    • That extends to business logic – e.g. the handling of the objects not just by AnonCreds, AnonCreds Methods and Aries Frameworks, but also by business applications built on Aries.
    • Suggestion:
      • Include in the specification a statement about backward compatibility
        • Perhaps this is what Ankur had planned to do?
      • Formalize what data structures will be expected by AnonCreds
        • This is being done throughout the specification and verified against the current implementation.
      • As needed support sending and receiving data in "old" and "new" formats, but (for now) always sending "old" formats.
        • TBD if there are any such cases.
  • Ankur to add paragraph about philosophy of the AnonCreds API, styles
  • Review the Issuing and Presentation sections to exclude Legacy Indy impacts, and to formalize the Abstract API for writing/reading published objects
  • Cred Def Generation + PRIVATE_CRED_DEF -- non revocation, and plus revocation
  • Normative/Non-normative references
    • Collect from documents mentioned below (under action items) and from previous meetings
