    • 08:38:15 From Kim Ebert : why wouldn't we send the OCA Bundle (or a pointer to it) with the credential at issuance or sharing
    • 08:39:11 From Daniel Bluhm : Would there be any indication on a ledger of the existence of the bundle on the resource server associated with a schema?
    • 08:42:43 From Daniel Bluhm : I'm assuming we'd need to do things like hashlinks to help ensure data resovled is data we intended to resolve
    • 08:46:13 From John Nathaniel Jr. : Must have a signature and a DID agreed.

Announcements

Deployments and Work Updates

Agenda

  • Updates on merges and current PRs – priorities
  • 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 (question) 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
