Agenda

• Updates on merges and current PRs – priorities
  • Merges Since 0.7.4
  • Open PRs
  • Status of reaching full AIP 2.0
• Presentation and discussion on enabling OCA for Aries in general and in ACA-Py specifically
  • MRGs and OCA – how to link them
• Update on last week's discussion and ledger agnostic AnonCreds in Aries/ACA-Py:
  • How to enable object (DID and AnonCreds) resolution to improve ledger agnostic Aries protocols, and in particular, ledger-agnostic AnonCreds
    • Topics:
      • DID Resolution:
        • State of DID Resolution in ACA-Py – local and external resolvers, regex to define if and how to resolve a DID.
          • External resolvers – http and didcomm interfaces available
        • Work happening now on did:peer to make it fit the interface
        • Working happening at SICPA on a DID Registrar based on the DIF Spec - Issue to be added to discuss/track
          • EBSI plugin being created (Ethereum based, DIDs only)
          • Plugins needed for did:sov, did:indy, did:peer, did:key  and folks may be interested in adding more
        • Inconsistency in returned DIDDoc – suggests the need for a method in ACA-Py to "smooth out" the handling of DIDDocs - Issue to be added to request
      • AnonCreds Objects Handling
        • Currently tied to Indy – a "baseLedger" class with instances for Indy-SDK (indy-wallet storage only) and Indy VDR (indy-wallet or askar storage).
          • Handles writing as well, with Endorser handling.
        • Likely need to abstract to a similar, pluggable resolution and writing mechanisms - Issue(s) to be created.
          • Given an identifier in an AnonCreds object/context – resolve it.
          • Write AnonCreds objects using plugins to various target VDRs.
        • AFJ starting to talking about an AnonCredsResourceService
