AIP3

• HackMD from the last Aires WG meeting, regarding AIP 3.0 

From our last meeting:

• Introduction
• Our current spreadsheet https://docs.google.com/spreadsheets/d/15noWiG_zhhUpornhrZm9cLEjQ1aa6z9qgJgPCaaIbtY/edit?usp=sharing
• AIP3
  • HackMD from the last Aires WG meeting, regarding AIP 3.0 
  • Great document by Hakan, looking at past AIP definitions and beginning to consider AIP3 definition 
  • Connectionless DIDComm v2 still needs management of the 'connection' between agents.  How should agents handle this?
    • Is this worth detailing/discussing or is it just agent specific?
    • OOB/handshake/discovery RFP for Aries agents?
      
      • WACI and what the overlap and distinction would be between the AIP and WACI.
        • There is some nuance to cred formats you have to support (Indy, BBS+, LD).  
        • Can we use Discovery protocol to understand the level of WACI support?
          • perhaps we need more detailed information from the discovery protocol
          • per application protocol supported (formats, messages, crypto).
          • Some WACI information to consider https://identity.foundation/waci-presentation-exchange/#format-property.
      • Encryption envelope selection
• Bruce Conrad is working with students to implement DIDComm v2 in their Pico environment.  Might benefit from JFF work
