Technology Architecture TF — Wenjing Chu  Drummond Reed

• Work on this was delayed until after IIW. Drummond Reed is going to be back on the job of converting it to Spec-Up and publishing Public Review Draft 2 before EIC.

Trust Registry TF — Andor Kesselman Antti Kettunen  Darrell O'Donnell

• No direct feedback at the moment—some conversations with Animo.
• Judith asked why an API-based registry vs. a downloaded file such as specified by the DIF Trust Establishment specification.
  • Darrell O'Donnell explained that the API model is more flexible and can handle more use cases, including non-credential based use cases.
  • The API model also enables existing registries to expose the registry data that they already have in a standard way.
• Judith also asked about how the OpenID Federation compared with the TRP? Darrell confirmed that an OpenID federation should also be able to expose their data via the TRP.
• Judith also asked about the Open Identity Exchange proposal for a "policy resolver" that could read and resolve what needs to be done to apply policies from one ecosystem to another.
  • This could apply to producing derived credentials.
• Jo asked the question about whether the TRP will be implemented as a trust task protocol that runs over the TSP.
  • We discussed the various reasons it might be helpful to have a TSP relationship with a trust registry:
    • For strong security.
    • For privileged access.
    • For privacy-protected access.
    • For a persistent connection, such as for push updates.

X.509 VID Task Force — Eric Scouten Wenjing Chu

• Eric, Drummond, and Scott Perry held a session to discuss the technical and business case for CAs adding a DID or VID to the Subject Alternative Name field of an X.509 certificate. There was a high degree of interest in "building that bridge"—including from one CA attending (Lori Groth of Digicert - https://www.linkedin.com/in/loriegroth/).
