    • https://github.com/hyperledger/aries-rfcs/pull/591
    • We need new RFCs for the Indy AnonCreds, JSON-LD and BBS+ sub-targets to describe the credential exchange attachments for each
      • Daniel Hardman agreed to create the Indy one
      • Timo Glastra agreed to create the JSON-LD VC format one, with help from George Aristy
      • The BBS+ one will likely be an evolution of the JSON-LD one
      • Draft and review preparation to be done for next week's meeting.
    • Remove Credential Manifest as a sub-target
      • Timo Glastra is working on a minimal implementation of a replacement suitable for the issue-credential protocol and will include that in the new RFC mentioned above.
    • Presentation Exchange RFC – George Aristyto review/revise the RFC 0510-dif-pres-exch as needed, mainly to nail down the specific version of the PE spec to use.
    • DIDComm message envelope RFC – Troy Rondato provide an overview of his RFC 0587 PR, including, effort needed to add support to the frameworks, what a community update would look like, and how to use OOB (and DIDDoc?) to express what is supported by the sending agent.
      • Really hope to see Tomislav Markovski Andrew Whitehead Timo Glastra at the meeting to assess the impact on the three major open source Aries implementations.

Next Week
