Discussion Topics

• The vc-di attachment – RFC 809, proposed changes in PR 828
  • Briefly discussed, but the PR submitter was not there and so didn't make progress. Perhaps next week.
• Adding the "stalled" RFC Status and reclassifying PRs – see Spreadsheet summarizing the proposed changes.
  • Goal is to make the published Aries RFCs easier to use.
  • Published Aries RFCs To Do list – Help welcome!
  • Progress:
    • Went through the spreadsheet, touching on each RFC with a proposed change of status, the purpose and reason for the change.
    • Identified a set (marked "Review") that are to be looked at before changing the status
    • Agreed that the next steps are:
      
      • Remove the ones to be reviewed from a change.  A new PR will be added that proposes any changes to the status of those RFCs, if needed.
      • Add the additional status changes proposed by James Ebert to the PR.
      • Merge the PR at that point.
  • We also looked again at the published Aries RFC site and the to do list of things to make the site better.
• Update: Adding DIDComm v2 Support to ACA-Py – First Impressions
  • Link – ACA-Py branch with DIDComm v2 changes: https://github.com/hyperledger/aries-cloudagent-python/compare/main...Indicio-tech:aries-cloudagent-python:feat/didcommv2-proof-of-concept
  • Link - New DIDComm Utilities Library: https://github.com/Indicio-tech/didcomm-messaging-python
  • Initial Progress - added code to ACA-Py to receive and unpack a DIDComm V2 message.
  • Best approach to the overall implementation still being fleshed out.
• Trust DID Web – did:tdw – brief overview based on this presentation used at IIW
  • An enhancement to did:web that provides a web-based DID Method with a verifiable history, authorized updates and portability (and more!) to a DID Method that has an implementation that is less than 1000 LOC in Typescript.
