    • Charter Draft: https://docs.google.com/document/d/1F6RbR7xDaBt5CDJhqLJzR4c1pDJtyPGshp9fy6eVtSM/edit\
      • Changes in suggest mode

    • Discussion Topics:
      • Stated Purpose of Project
        • "create shared, reusable, interoperable, and scalable agents for developing critical decentralized trust solutions, including the use of verifiable credentials and communication technologies." 
        • intent is to be DID method, credential type, and communication protocol agnostic. ledgers are acceptable but not required
        • we expect these agents to represent organizations, people, and things, and take action by direct subject interaction and also subject approved automation
        • From ChatGPT based on the above:

          • ### Stated Purpose of the Hyperledger Aries Project

            The mission of the Hyperledger Aries Project aims to create shared, reusable, interoperable, and scalable agents for developing critical decentralized trust solutions, including verifiable credentials and communication technologies. It is designed to be agnostic regarding DID methods, credential types, and communication protocols, with ledgers being optional. These agents will represent organizations, people, and things, capable of taking actions through direct interaction or subject-approved automation, fostering robust and flexible decentralized trust solutions.

  • Unqualified DIDs 
    • https://hyperledger.github.io/aries-rfcs/latest/features/0793-unqualfied-dids-transition/
    • Progress?
      • ACA-Py working on 1.0, this will be the SECOND major release (0.12.1) of ACA-Py that has accomplished step 1
      • Ongoing successful testing with Credo.
    • did:indy handling
      • unqualified anoncreds objects being rejected
      • did:indy changes the unique identifier within the DID. both the old method and the new method should work.
      • Credo is using did:indy only, cannot resolve unqualified asset identifiers.
      • Rushed work to address within AnonCreds RS ( ? ) and ACA-Py. 
      • quicker fix in Credo, longer fix in everything.
    • PRs for adoption status welcome
  • OOB Invitation / DID Exchange CCU
  • DIDComm v2 adoption
    • ACA-Py progress shared last week
      • PR made for initial support. first round trip support.
    • Any other updates?
    • Credo has the beginnings of DIDComm v2, but does need some attention.
  • In person offline presentation
    • Transport
      • BLE DIDComm transport
      • ISO/mDL
    • Caching Strategies
      • Knowing what to cache
        • Credential Trust Establishment spec
      • Keeping things cached, and use cached state
        • verifier decides if it's new enough
        •  
      • revocation check
      • don't include proof of non-revocation if not asked
        • can't be ignored?
    • don't do indy edits on cred defs and schemas
      • is this already a rule? if not, it should be.
      • edit rule does exist. but why?

      • prove well known dids other than the current connection.
    • JSON-LD creds impl within ACA-Py no longer working with Credo 0.5.0
      • Sphereon library using for Presentation Exchange objects is not expecting quite the same things, additional fields.
      • Daniel working through and testing, will report / create issues on the appropriate repos.
      • Updates?
      • Fix merged into ACA-Py. 
        • funny interactions between the speheron libraries and credo about presentation exchange. - issues raised to Timo et. al.

  • Mediator Reconfig revisit
    • (from last week)
    • 3 new messages
      • updatedconfig - new routing DID
        • note about timing or avoiding causing a traffic stampede as a result.
      • ack- received by 
      • updated downstream (keylist updates as alternative?)
    • need for this:
      • anytime a mediator needs to change the routing DID
      • static DID, but also other cases.
    • loss of data at the mediator
      • all routes lost.
