  • Wishlist / Goals?

    • Features that may not be necessary - patrik

    • reverting .1 and .2

    • abandoned state - if a user declines to present, what should happen between the holder and verifier?

      • problem report sent 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.

    • 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.

      • requirements for DID methods that resolve to cred related assets

    • return of supplements

    • make sibling protocols for each credential type instead of being universal?

    • Different protocols for different sections?

        • we need to be careful not to match protocol to UX on a 1 to 1 basis

• Twilio’s WebRTC offering is being retired (https://www.twilio.com/en-us/changelog/programmable-video-eol-notice)  Anyone interested in collaborating on a WebRTC/DIDCommV2 protocol ?

• 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?
