• New TSWG call schedule - see this new text added to the TSWG home page:

Because there has been some confusion on everyone’s part, I just published the four-week rotation of Technology Stack WG + TF meetings that happen on Wednesdays on the TSWG home page. To make it easier for everyone, here’s a copy:

The TSWG currently holds a plenary meeting once every four weeks. The current NA/EU meeting slot is Wednesdays at 08:00-09:00 PT / 16:00-17:00 UTC. The TSWG shares this Wednesday NA/EU meeting slot in a four-week cycle with three other TSWG Task Force meetings, each of which also has a second APAC meeting also on Wednesdays at 18:00-19:00 PT / 02:00-03:00 UTC. The full four week cycle (which started on 04 January 2023) is:

1. TSWG Plenary (NA/EU only)
2. Technology Architecture Task Force (NA/EU + APAC)
3. Trust Spanning Protocol Task Force Meeting #1 (NA/EU + APAC)
4. Trust Spanning Protocol Task Force Meeting #2 (NA/EU + APAC)

• We WILL be adding an APAC call for this meeting, starting in the next cycle.

ACTION: Drummond Reed to request Judith Fleenor and Michelle Janata to add the TATF APAC meeting on Wednesdays at 18:00-19:00 PT / 02:00-03:00 UTC to the ToIP Calendar. 

• New volunteers joining TSWG leadership

See the TSWG home page.

• Some feedback on the ToIP Technology Architecture V1.0 Spec

Allan Thomson The actual implementations are going to be what audiences are going to be most interested. So it shows that we need the components specifications and interoperability profiles.

Antti Kettunen shared that the paper seems "more academic" to a business person. A technical contact understood it better. It requires "selective readership".

Matthieu: the model clarified that what ToIP is proposing provides an overall framing of how the different components and protocols can fit together. Being able to see where other technologies fit would help.

Judith Fleenor said that we didn't include that many examples of where specific existing technologies fit. We could do a blog post that helps point out where specific technologies fit into the stack. "If they see themselves in there, they can see where they will fit."

• More expected once we launch the Trust Spanning Protocol TF (below)
• See also the proposal from Daniel Hardman on the Grand Unified Theory (GUT) for greater collaboration between industry ords in the decentralized identity space. 
  • Link to the recording. Source: DIF DIDComm User Group - special presentation on broadening collaboration across ecosystems
  • Daniel said there has been a flurry of activity since his talk about how KERI and DIDComm can come together, particularly around peer DIDs. Those conversations were primarily in the KERI and Hyperledger Aries communities.
  • There were also requests to tie it into the DIF DIDComm Working Group activities.
  • With regard to the trust spanning protocol, it has implications for where we start. For example, we want to look at different potential source protocols could be "pulled in", then the work on KERI and DIDComm convergence would not come into the trust spanning protocol work until later. However, if we start down a path where the DIDComm and KERI and Aries work becomes immediately relevant.
• Allan Thomson said it's very important that we make the right tradeoffs in the TSP and that requires knowing what use cases it needs to support. It's like designing a pipe without knowing what will go through it. So knowing what those "canonical use cases" are is vital.
• Lance Byrd said that the timing is excellent for the Aries community as they are trying to develop the Aries Interop Profile 3.0 is defined. It is a good connection point within Aries.

The TSPTF charter was approved at last week's TSWG Plenary meeting.

Wenjing Chu, Daniel Hardman, and Drummond Reed have volunteered to lead.

The hope is to move fast (and not break things, just reduce things). The aspiration is to have a draft by June. And implementations!

• Daniel Hardman has been working on a draft of what might be the next version of DIDComm, but that particular document doesn't necessarily relate to the work of the TSPTF — that is still to be determined.
• So in terms of timeline, it's hard to predict how long it will take to get alignment.
• Lance Byrd said there's an Aries DIDComm V2 working group and a lot of the attendees who want to see the Aries agent test harness can be used to validate their DIDComm V2 agent interop. So part of the reason that AIP V3 was launched is to help move toward this work.

Please do join the first meeting next Wednesday.

Review the open issues.

• Special mention: we need to update our conceptual diagram of the ToIP stack (see screenshot #1 below)
• Another task is to insert use cases — the task we originally handed to the Ecosystem Foundry WG but which they handed back.
• But the biggest remaining task is terminology and glossary — see next topic.

ACTION: Drummond Reed to coordinate work on closing open issues via our Slack channel so we make maximum progress in the next four weeks.

• Allan Thomson asked what stake we are willing to put into the ground for finalizing the TAS.
• Drummond Reed shared his view that the earliest he estimated the remaining work could get done is mid-February, but that the latest should be end of Q1.
• Allan suggested that we target the end of Q1.
• Drummond agreed but proposed that we target the final vote of the ToIP Steering Committee for the end of Q1. After Drummond researched SC dates, the closest SC plenary meeting is either March 8 or April 12. So to finish before the end of Q1 would mean, working backwards, the following milestones:
  • March 8: ToIP Steering Committee vote to approve the Working Group Approved Draft. 
  • February 22: Technology Stack WG vote to approve the Working Draft.
  • February 15: Final Working Draft completed and ready for TSWG review.

That would leave us a little over a month to complete the remaining tasks/open issues.

DECISION: Our goal will be to publish the final draft of the ToIP Technology Architecture V1.0 Specification and have it approved by the ToIP Steering Committee by the end of Q1.

Neil Thomson and Drummond Reed have point on this.

• The Concepts and Terminology WG has identified a developer (Brian Richter) to develop the Terminology Toolbox 2.0, but it won't be ready until Q2. So we'll need to develop our TAS glossary semi-manually.
• The initial work is determining all of the glossary entries (Neil) and then writing them up (Drummond will help herd the cats).
• We didn't pick up any volunteers on the call, but we'll need some to get the job done.

ACTION: Drummond Reed to arrange another followup meeting on glossary items with Neil Thomson next week.

Judith Fleenor reminded everyone that next Wednesday at 10AM PT is the first 2023 All-Member meeting that will go over the SSI Harms white paper from the Human Experience WG.
