Meeting minutes

Phil Archer: good day everyone

<Elaine Wooton> i have no mic :( but am present

Phil Archer: no one new here.
… all we're planning to do here is to talk about next week
… in Brussels
… and a quick round up with Task Forces
… Anything to add?

Manu Sporny: the quantum resistant spec people picked a name
… I'd like to put that in front of the group

Phil Archer: sure.
… So just a bit of time about next week's meeting.
… for some, that's a remote participation. for some face to face
… should be fully able to join, modulo timezones
… We've given the address. There's a person at reception who should expect you.
… Go to fifth floor (they'll know that)

<Elaine Wooton> yes

Phil Archer: Is it still the case that the barcode & data integrity group want to meet Monday afternoon
… Yes, it is. Great. I'll see you on Monday afternoon
… Set for 2pm local time
… Then we kick off properly tuesday morning

<Phil Archer> https://docs.google.com/spreadsheets/d/1h-0OXOR5NsY-OlC0i26mCDK45B15j2BfkL8f2CIY30E/edit?gid=0#gid=0

Phil Archer: a small change in the agenda
… the thing that got switched around, which I'm concerned about, because Susanna is able to join on Wed morning
… The problem is the other person, can't be there Wed

Carolynn Bernier: Yes, I can.

Phil Archer: Great! That fixes that.

Kevin Dean: I might be able to join remotely for DPP

Phil Archer: the agenda was worked out primarily based on timezone of remote participants
… that's why Confidence Method is AM and render method is afternoon
… Do take a quick look. Is there anything there that is going to upset anyone?

Carolynn Bernier: How can we see the agenda?

Phil Archer: in the chat?

<Phil Archer> https://docs.google.com/spreadsheets/d/1h-0OXOR5NsY-OlC0i26mCDK45B15j2BfkL8f2CIY30E/edit?gid=0#gid=0

Carolynn Bernier: I see a link ...

Carolynn Bernier: Ah... now I see it.

Phil Archer: a couple other things. a relatively small group
… the bad news is there is no cleaner. we are the cleaners.
… WE put the plates in the dishwasher
… The upside, when it gets to social event, GS1 is going to pay for that
… Pay for the entry ticket. Not all the food, but the museum ticket.

<Manu Sporny> Thank you to GS1 for covering everyone's entry ticket :)

Carolynn Bernier: On Wed?

Phil Archer: Yes, Wed afternoon. I'm booking tickets today.
… down and Boors[sp?]

Carolynn Bernier: Can I invite a friend from the commission?

Phil Archer: We leave the meeting at 3. So, yes, but I need to know that person.

Carolynn Bernier: Seth

Phil Archer: Seth Van Holland. Ok. Alright.

Kayode Ezike: Is there going to be a room?

Phil Archer: yes, same link for remote participation

Ivan Herman: yes. that makes life simpler.

Phil Archer: Yes. a link in the calendar, and the same IRC channel as well

Phil Archer: also Tuesday, our CEO would like to come meet us over lunch. And a few other colleagues.

Ivan Herman: will there be some sort of AV equipment for remote participants to show up and participate

Phil Archer: yes, there's a modern thing with the magical camera that points at speakers

Joe Andrieu: Disc golf on Friday

Phil Archer: Is everyone staying at the Moxi?

Ivan Herman: no

Joe Andrieu: no

Will Abramson: I will be

Brent Zundel: I want to reiterate that the task force leads to prepare for their session
… for example, the VCALM TF is Wed. We are going to turn to you and say "Go"
… we'll handle the queue, scribe, and logistics, but the actual content is up to the task force themselves
… if you want slides, please make them
… if you want a session focused on issues / prs, that's fine too
… The chairs are not actively planning every session

Joe Andrieu: Phil you got the Use Case conversation under control?

Phil Archer: Yes.

<Phil Archer> https://w3c.github.io/vc-dpp-bw/ucr/index.html

Phil Archer: after introduction, we have a discussion of the uses case.
… There is a new use case document for the business wallet
… quite a lot of which are use cases for VCs
… we need to think about which of those, if any, we are going to put in the primary use case document
… given that we now have a lot of task forces in flight
… with lots of different work going on.
… maybe that means the use case document needs updating
… I would ask, while you're traveling, at least skim that use case document?

<Phil Archer> https://www.w3.org/TR/vc-use-cases/

Joe Andrieu: Short request, can you get URLs in agenda or in calendar item?

Joe Andrieu: It will help people find the URLs.

Phil Archer: apart from that, we are pretty much ready to go.

Phil Archer: we'll deal with logistics on site.
… for remote participants, the equipment is up to date, and we will make every effort to include remote participants as equals so you feel valued, because you are
… Usually the week after, there are no working meetings. I'd recommend cancelling the the week after.
… Up to task force leaders to decide for their group

Carolynn Bernier: we discussed splitting the group, between two subjects separately. Combined vocabulary discussion isn't very productive at this point.
… So, how can I control a meeting? I didn't send the invite, how would I cancel it?

Phil Archer: I can point you to it now.

<Phil Archer> https://www.w3.org/groups/wg/vc/task-forces/

Phil Archer: If you go to that URL, that has all the task forces.
… Go to your task force, you'll see the calendar link. And you should be able to confirm/cancel whatever
… What usually happens, you put the agenda in and mark it confirmed.

Ivan Herman: Question for Carolynn Bernier. The cut of the two topics, is that just separate meetings?

Carolynn Bernier: Yes, we are thinking a biweekly meeting for each.

Ivan Herman: We could also split that task force, but there aren't a lot of people to support that

Carolynn Bernier: We will also meet together sometimes

Ivan Herman: That is entirely between you can Carsten to set the agenda.

Carolynn Bernier: So we keep it as a weekly meeting, then set the agenda by editing the event

Phil Archer: Yes. Should be easy.

Ivan Herman: We meet in person next week, so let's do it in person.

Carolynn Bernier: Thanks.

Phil Archer: Any other questions for next week?
… next up for task force
… wait. before I do that.

Post Quantum

Phil Archer: Manu Sporny you wanted to discuss the post-quantum

Manu Sporny: thanks, Phil
… Yesterday on data integrity task force call, we settled on Quantum Resistance Crypto Suites, as vc-di-quantum-resistant-1.0

Phil Archer: this has been around. incubated in CCG

Manu Sporny: Yes. It's been around for a while. Ready to publish through this group.

Phil Archer: As it was moved, all the IP commitments were made.

Manu Sporny: Yes

Ivan Herman: You've made all the admin steps? Publication either 16th or 18th of June

Manu Sporny: Correct

Phil Archer: Any comments? before we formally put this to the group?

<Manu Sporny> PROPOSAL: Publish the Quantum-Resistant Cryptosuites v1.0 specification (https://w3c.github.io/vc-di-quantum-resistant/) as a FPWD with a shortname of vc-di-quantum-resistant-1.0.

Phil Archer: Then I think we good to go

<Kayode Ezike> +1

<Phil Archer> +1

<Joe Andrieu> +1

<Manu Sporny> +1

<Dave Longley> +1

<Ivan Herman> +1

<Wesley Smith> +1

<Steve McCown> +1

<Ted Thibodeau Jr.> +1

<Will Abramson> +1

<Elaine Wooton> +1

<Benjamin Young> +1

Phil Archer: congratulations. that's another FPWD from this group.

RESOLUTION: Publish the Quantum-Resistant Cryptosuites v1.0 specification (https://w3c.github.io/vc-di-quantum-resistant/) as a FPWD with a shortname of vc-di-quantum-resistant-1.0.

Ivan Herman: Food for thought, Manu Sporny. Usually when there's an FPWD, there's news that W3C issues. A standard thing, an abstract of the spec
… in view of quantum panic, is it worth asking the comm team to do something more than that?

Manu Sporny: Yes. I think that's a great idea.
… it would signal to the greater web community that the W3C is working on post-quantum things

Ivan Herman: Ok. I will ping you when the time comes.

Phil Archer: That is interesting, because it does show that the group is working on the race between good guys and bad

Phil Archer: While you have the mic, Manu Sporny any news from the barcode and DI group?

Manu Sporny: no, but I'll defer to Wes and Elaine Wooton

Wesley Smith: Plan for the week is to do what we've been doing: discussion, issues, PR processing

<Elaine Wooton> +1

Wesley Smith: we are looking for a forgery defense that plays well with QR codes, which happens to work well with post-quantum

<Manu Sporny> I like the new "forgery defense" moniker... because it's not just about quantum resistance.

<Dave Longley> +1

Wesley Smith: Not sure if Greg Bernstein might have specific things to bring up

<Elaine Wooton> no mic!

Phil Archer: That's a Thursday morning meeting

Joe Andrieu: Denken and I don't have a full plan for next week yet, but I expect we're going to focus on the Realeyes PR.

Phil Archer: render method? I don't think we have Dmitri. Can anyone else talk about it?

Benjamin Young: I'm happy to talk about render method
… the group is trying to figure out what they can prune or not prune for the sandbox stuff
… we are trying to figure out how many problems that approach solves
… There's been discussion around how many things that can solve.
… Also interest in other formats
… So you can highlight important fields
… Patrick St Louis has been talking about OCA bundles
… Perhaps an approach about credential types

Phil Archer: Benjamin, can you talk with Dmitri about how you are going to use that time.
… Carsten isn't on the call. Carolynn Bernier?

Carolynn Bernier: I just checked with Carsten. He's going to lead the wallet vocab on Wed morning next week.
… I will lead follow up meeting on DPP
… Content will be getting to know DPP team members and define the scope and related work
… There is a lot of related work.
… We need to list those and discuss how these different activities will affect what we are trying to do.

Phil Archer: That sounds like a good conversation for the hour 15 we have for you. Thank you

Phil Archer: Kayode, VCALM?

Kayode Ezike: What we've been talking about recently, include Threat Modeling
… Also test suite development.
… There was a VCALM test suite under CCG. We've been working on refactoring that.
… Third, is just maintenance of the spec. Issues and PR processing.
… Manu Sporny proposed a way to categorize these as post 1.0, so its not a blocker for the current charter
… I'll chat with Patrick and Manu Sporny about managing queue remotely
… And we'll probably need to give a bit of background

Phil Archer: Yes. The group is too large for everyone to participate in all task forces,
… This is the opportunity to share the work with participants in other task forces
… All of this work affects our peers work.
… We're all in the VCWG.

Phil Archer: one request. I'm having difficulty hearing you. A microphone would make a big difference.

Kayode Ezike: how about this?

Phil Archer: Yes, that's great.
… next up Recognized Entities

Manu Sporny: we are going to go over at a high level what this does
… probably talk about alignment with GS1 and UN Grid use cases(?)
… And threat model
… If we have time, we'll focus on the issues we really need to address before candidate rec

Brent Zundel: Noting there is a VCALM session separately as a task force. There are also two threat modeling sessions

Joe Andrieu: I think Simone is trying to be there in person. Might talk about VCALM earlier in the process...

Joe Andrieu: Simone has learned that being concrete early on is good, so VCALM is a good candidate.

Phil Archer: my aim while we are there. by the end of the day, we should get a sense of where the group is as a whole.

Phil Archer: Also TPAC

Phil Archer: we will have some in CR by TPAC

Joe Andrieu: We did move VCALM to Thursday, so that's fine.

Joe Andrieu: Also finishing up respec-threats library so plan to spend some time on that in F2F.

Joe Andrieu: Eric also has some useful DFDs to discuss, but want to talk about overlap and Eric's work on threat models (top level diagram for moving parts) -- Eric broke it up into concrete use case, and diagram for each step, re-using same components... help us get to granularlity we need for threat analysis.

Joe Andrieu: Folks might want to look at those diagrams before attending.

Manu Sporny: +1 to that.
… back to the question Brent Zundel asked.
… I heard Simone might be there in person. I'm happy to help.
… I'll volunteer
… Item 2. Yes, that's for the respec threat modeling extention. I'm going to try applying it to other work maybe to recognized entities.

Phil Archer: Benjamin, you were asking about the two spreadsheets.
… Yes. Sorry about that.

Benjamin Young: Any objections to me leaving signpost

<Phil Archer> https://docs.google.com/spreadsheets/d/1Emo_yVt90Z5xnHNBPhShO4B7zYQ7kwMfNcOa6sKAdoc/edit?gid=179611341#gid=179611341

Phil Archer: I'm not taking the attendance spreadsheet as final.
… In particular, I'm using those numbers to book our tickets for the Wed evening

Ivan Herman: A practical thing. Unfortunately, it will be pretty rainy next week. Bring umbrellas!

Thanks, Ivan Herman!

GS1/W3C workshop on Agentic AI for retail

<Phil Archer> https://w3c.github.io/ecommerce-for-humans-and-AI-Agents-workshop/

Phil Archer: In case you don't know, it's wetter than London.
… Completely separate topic, in case its of interest.
… I am working with W3C on workshop in September about agentic AI, MCP, UCP, ACP< etc. I'm putting together the program. Bosch and Visa.

If that is of interest to you

Joe Andrieu: remote participation for workshop

Phil Archer: Yes.
… Thank you all. See you need week, in person or online.
