Agenda

    • How to handle auto-endorse?
  • Describe Feature/Event Bus
    • Goal - webhooks to other parts of ACA-Py, Plugins to ACA-Py (vs. multiple external listeners)
      • A layer between event creation and subscribers to allow internal subscribers
      • Use case – plugin subscriber to push events to a Kafka queue.
      • Need to update the persistent queue work – make it a plugin?
      • How to convey how/when to use this to other developers
      • Integration test or walk-through of how to use.
• Issues: 
  • Too many!  Need to have a culling. 94
  • Hot ones?
    • Problem Reports
      • Key Case: Receiving PR within the Credential Exchange to do clean-up, etc.
        • Change the message family
      • Also important - sending Credential Exchange specific PR.
      • PR schema with the RFC.
    • JSON-LD Performance - contexts are not cached.
      • Once BBS PR is merged, does some replacements with re-route.
    • Aries Go Interop – base64url, recipientKeys/routingKeys, DIDDoc
      • Addressed in "small AIP 2" PR.  Or at least should be...
• Progressing on initiatives; priorities
  • Adding a JSON-LD, BBS+, PE Demo
    • What keys, what ledger?
