      • negotiation pulled out into a sibling protocol - (nobody using negotation? Subhasis referenced use.)
        • propose message moves to different family.
      • Document the short-circuted use of the protocol that starts at issuance directly, depending on needs of credential type.
      • we need to be careful not to match protocol to UX human steps on a 1 to 1 basis
      • abandoned state - if a user declines to present, what should happen between the holder and verifier?
        • problem report sent (or no message, see below) on decline - should be documented
      • offers that sit for a long time at the holder
        • documenting a timeout for the offer.
        • use of timing in thread decorator
      • Removal of any reference to payments.explicit 'no' messages instead of a problem report when it's an explicit no, instead of an error.
      • document use of timeout for offers (didcomm v2 friendly, perhaps a field within the protocol.

      • different protocols for different credential types? (needs discussion)
        • make sibling protocols for each credential type instead of being universal?
      • preview model doesn't work for vc data model creds. could allow an unsigned version of the credential being issued.
      • nobody using negotation? Subhasis referenced use.
      • cred def reference - did:indy and language that makes clear DIDs can (should?) be used.
        • requirements for DID methods that resolve to cred related assets
      • return of supplements
        • make sibling protocols for each credential type instead of being universal?

Future Topics

...

  • decorator for redirection after proofs. - existing?
  • in the Aug 9 call there was talk about EUDI compatibility. Maybe tracking the progress every now and then in these calls? Has there been any discussion about adding SD-JWT and OID4VC stuff to Aries Interop test suite?
