Outcome & Work Items

RFC 496 - Transition to OOB and DID Exchange From 2021-11-16 Session

  • To do: Chase wallet vendors, share findings, and update RFC Stephen Curran

How are we really going to do deep-links? From 2021-11-16 Session

Handling HTTP on mobile, since mobile OS's require an exemption to use HTTP. DIDComm over HTTPS results in double encryption. From 2021-11-16 Session

Auto-approval of presentation requests. From 2021-12-07 Session

  • Can be risky, e.g. auto-presenting could lead to interaction-less login
  • One aspect: bulk approval (present series of proofs with one user action to approve)
  • Another aspect: policy approval (conditions by which an approval or other user action can be automated)
    • Care needed on: anti-patterns, security vs. convenience, following SSI principles, fiduciary responsibility when agents work on behalf of users
  • To Do:
    • Needs bulk presentation request (Present Proof) (mostly done)
    • Needs policy to recommend bulk actions
    • Policy approval is complex and needs more investigation

Machine-Readable Governance and UX. From 2021-12-07 Session

  • Introduces new types of user interactions
  • Has many types of governance: root of trust, identifying participants, etc.
  • Mike is working on test applications of Machine Readable Governance

Credential UX

UX of Invitations

  • Development of Machine Readable Governance
  • Development of language around trust
  • To Do: Need Proposed Initial Attempt as an Aries RFC - Sam Curren

Mobile Verifiers

  • Inversion of QR scanning flow where verifier scans holder's QR code
  • Other mechanisms other than QR Code (e.g.: BLE)
  • Todo: Summary of existing state for BLE
  • Todo: Summary of existing state for NFC
  • Todo: Document use cases and UX flows

Device Backup/Recovery

  • Define interop format for backup
    • Not everything can be backed up. Some credentials may only be usable in the device/wallet it was issued to 
  • Define a backup service protocol

Error Handling and Reporting

  • We don't currently have enough published community knowledge to organize the conversation very well.
  • Errors need to be communicated at both a technical level and a human level
  • Context for errors is important - don't imply that background errors relate to a different foreground operation.
  • ToDo: Need a focused convention of agent developers to share the errors they handle and how, with a goal of capturing community knowledge and best practices.
