20 minsUpdate on Working Draft progressWenjing Chu 

Check-in to see how close we are to an Implementer's Draft. Key updates:

  • Section 5 was moved.
  • Wenjing started on sections 9 and 10 to provide at least enough for implementers to get started. In particular, we need to explain at least the basic transport protocol binding options, and also refer out to CESR. 

Wenjing said that he's had a chance to talk to some developers interested in implementation and they are relatively satisfied.

5 minsProposed VID/DID/SCID diagram

Darrell O'Donnell Drummond Reed 

Over the break, Darrell created the diagram in screenshot #1 below. We are proposing to use this as the replacement for Figure 6 in section 6.4 of the ToIP Technology Architecture Specification. 

This led to a long discussion about VIDs, the meaning of cryptographically verifiability, appraisability, and the tradeoffs of "big tent" vs. high assurance. The result was two design decisions (which still need consensus on the. APAC call):

DECISION: Section 3 of the TSP spec, Verifiable Identifiers, will be the "mini-spec" for VIDs, including the ABNF. We will not break it out into a separate specification because it is so integral to the TSP (just as the spec for IP addresses was integral to the Internet Protocol specification).

DECISION: Our baseline approach to VID appraisability will be an optional VID type property that a verifier can use in conjunction with the VID value to make a baseline trust decision about the VID. In addition, to enable extensibility, the VID ABNF should also allow any URN, which includes DIDs.

15 minsFeedback on the current Working DraftALL

Review comments from TF members who found time to review the Working Draft over the holiday break (including the Slack threads).

We ran out of time to discuss any comments outside of the VID discussion above.

ACTION: Drummond Reed to add "Spec Feedback Review" to the agenda for next week's meeting.

10 minsPreparation for a Implementer's Kickoff MeetingLeads

If we are close enough, discuss the preparations we should make for holding an Implementer's Kickoff Meeting. How much lead time should we provide? How much should be covered in a blog post?

Wenjing felt that it was realistic for us to be ready within 3 meetings, i.e., by the end of January.

ACTION: Drummond Reed to add "Prepare for Implementers Kickoff Meeting" to the agenda for the next meeting.
