15:03:44 <bigbluehat> manu: there is a discussion over the last couple weeks around payments and digital credentials
15:03:53 <kezike> kezike has joined #vcwg
15:03:54 <bigbluehat> ... EMVCo did a presentation at the W3C
15:04:08 <kezike> present+
15:04:14 <bigbluehat> ... some of us were there and noted that there are W3C VC community members doing payments work at other organizations
15:04:37 <bigbluehat> ... some of those other orgs are also hoping to visit on August 27th to present some of that work
15:04:40 <bigbluehat> ... I can't make that call
15:04:45 <bigbluehat> ... but hopefully others here can
15:04:54 <bigbluehat> ... there are some asks from FIDO and EMVCo
15:05:06 <bigbluehat> ... and folks here could contribute review
15:05:14 <brent> q+ to say also at TPAC
15:05:16 <bigbluehat> ... as they've been asked to support W3C Verifiable Credentials
15:05:25 <bigbluehat> ... and it would be great for us to participate
15:05:40 <bigbluehat> phila: is that the FedID WG call on the 27th?
15:05:43 <bigbluehat> manu: yes.
15:05:51 <phila> The meeting Manu is talling about is https://www.w3.org/events/meetings/d593c94a-0cc3-4a92-ae85-f4024adf1f16/
15:06:12 <bigbluehat> phila: I was under the wrong impression that it was only for chairs, but everyone is actually welcome
15:06:21 <bigbluehat> ... I plan to be there and I hope others will join from this group as well
15:06:54 <bigbluehat> ... there are other events this fall where various standards will be being discussed together
15:07:06 <bigbluehat> TallTed: that call is actually already on the VCWG calendar
15:07:13 <phila> q?
15:07:15 <phila> ack brent
15:07:15 <Zakim> brent, you wanted to say also at TPAC
15:07:28 <bigbluehat> brent: there is also a joint meeting on the Tuesday of TPAC
15:07:38 <bigbluehat> ... if you've already registered, please consider attending that
15:07:59 <bigbluehat> ... one of the bolded options for you should be that joint session
15:08:23 <bigbluehat> phila: It's 1:30 PM on Tuesday--Ireland time
15:08:48 <bigbluehat> ... k. there's a list of things from manu for us to go through today
15:08:50 <dmitriz> q+
15:08:53 <phila> Topic: task Force updates
15:08:58 <phila> ack dmitriz
15:08:58 <bigbluehat> ... anyone else have other task force things to discuss?
15:09:32 <manu> q+ to note lots of work on threat models.
15:09:38 <bigbluehat> dmitriz: the Render Method Task Force agreed to ask the main group--this one--to do a resolution to start the horizontal review for our spec
15:09:39 <phila> ack manu
15:09:39 <Zakim> manu, you wanted to note lots of work on threat models.
15:09:45 <bigbluehat> phila: dmitriz can you draft that?
15:10:00 <JennieM> JennieM has joined #vcwg
15:10:05 <bigbluehat> manu: I actually have resolutions drafted
15:10:11 <bigbluehat> phila: great, let's use that/those
15:10:16 <wes-smith> q+
15:10:20 <JennieM> present+
15:10:20 <phila> ack wes-smith
15:10:23 <bigbluehat> manu: this isn't usually how we do it, but doing one proposal would simplify things
15:10:32 <bigbluehat> wes-smith: that list should include VC Forgery Defense also
15:10:37 <bigbluehat> manu: k. adding that.
15:10:55 <bigbluehat> phila: so, some context for those who might be need
15:11:03 <bigbluehat> ... wide review is a W3C distinguishing feature
15:11:33 <wes-smith> q+
15:11:35 <bigbluehat> ... we have Accessibility, I18N (Internationalization), Security, Privacy, and the TAG (Technical Architecture Group) review every standard
15:11:42 <phila> ack wes-smith
15:11:48 <bigbluehat> ... these things can take a bit, so we want to start them earlier than later
15:12:04 <bigbluehat> ... these are valuable reviews since the Web is for Everyone (per Tim Berners-Lee)
15:12:13 <swcurran> swcurran has joined #vcwg
15:12:26 <bigbluehat> wes-smith: we will need to link to these minutes as part of the request to the TAG (at least) when doing horizontal review
15:12:40 <manu> PROPOSAL: Request Horizontal Review for VC Rendering Methods, VC API for Lifecycle Management (VCALM), VC Barcodes, and VC Forgery Defense.

15:13:23 <bigbluehat> ... thank you to those who have made this happen!
15:13:44 <phila> Resolution: The VCWG requests Horizontal Review for VC Rendering Methods, VC API for Lifecycle Management (VCALM), VC Barcodes, and VC Forgery Defense.
15:13:57 <manu> q+ I have one more for the registration
15:13:59 <phila> RRSAgent, make logs public

15:14:39 <Zakim> manu, you wanted to note I have one more for the registration
15:14:52 <bigbluehat> phila: for wes-smith and anyone else who needs it, there is the direct link to the vote above
15:15:20 <Elaine> Post link again. Please. I was disconnected.
15:15:21 <bigbluehat> manu: it's good practice to register protocol and/or pseudo schemes at IANA
15:15:30 <bigbluehat> ... we have one in VCALM called `interaction:`
15:15:39 <Peter> Peter has joined #vcwg
15:15:41 <bigbluehat> ... and it supports multiple protocols
15:16:05 <manu> https://w3c.github.io/vcalm/#iana-considerations
15:16:16 <bigbluehat> ... this should actually help the ecosystem by building a bridges from user agents (Wallets, browsers) to various protocols
15:16:35 <wes-smith> wes-smith has joined #vcwg
15:16:48 <bigbluehat> phila: this is what goes at the front of the URI?
15:16:50 <bigbluehat> manu: yse
15:16:54 <bigbluehat> s/yse/yes
15:16:56 <Elaine> Add me +1
15:17:01 <bigbluehat> phila: is this contentious?
15:17:08 <bigbluehat> manu: who knows?! We don't think so.
15:17:24 <brent> q+
15:17:27 <phila> ack brent
15:17:32 <bigbluehat> ... the `web+interaction` URL is for web apps to be registered as Wallets
15:17:49 <bigbluehat> brent: as someone who is currently going through a failing URI attempt
15:17:58 <bigbluehat> ... I am not seeing the description of the URI itself
15:18:16 <bigbluehat> ... I see the scheme registration, but where is the description of what the URI actually looks like?
15:18:23 <bigbluehat> manu: are you asking about the ABNF?
15:18:37 <bigbluehat> ... I thought that was not needed until the final registration, not a provisional one
15:18:38 <dlongley> https://w3c.github.io/vcalm/#interaction-scheme-format
15:18:45 <manu> https://w3c.github.io/vcalm/#interaction-scheme-format
15:18:46 <bigbluehat> ... kezike may know more
15:19:03 <bigbluehat> kezike: we do have ABNF
15:19:20 <bigbluehat> manu: we could provide that. We do have it.
15:19:27 <bigbluehat> brent: all good. I just wasn't finding it.
15:19:41 <kezike> kezike has joined #vcwg
15:19:49 <bigbluehat> manu: some registrations have very little info and others have pages...so who knows how this will go
15:19:52 <kezike> q+
15:19:59 <phila> ack kezike
15:20:14 <bigbluehat> kezike: we should probably put the full scheme names in the proposal
15:20:24 <bigbluehat> manu: we mention that the spec talks about what they are
15:20:30 <bigbluehat> ... we could make it explicit
15:20:33 <bigbluehat> TallTed: yes, please do
15:21:10 <manu> PROPOSAL: Request the registration of protocol schemes listed in the IANA Considerations section, that is, interaction and web+interaction, of the Verifiable Credential API for Lifecycle Management (VCALM) specification via IANA.

15:21:58 <phila> RESOLUTION: The VCWG requests the registration of protocol schemes listed in the IANA Considerations section, that is, interaction and web+interaction, of the Verifiable Credential API for Lifecycle Management (VCALM) specification via IANA.
15:22:22 <bigbluehat> phila: whether you were part of the work or not, you are part of the group that approved this resolution
15:22:46 <bigbluehat> ... I understand that folks can't be in all groups, but we do act as a group for significant actions such as this one.
15:23:04 <phila> Topic: test suites and implementations
15:23:37 <bigbluehat> phila: we're heading into a few upcoming months where test suites need expansion or creation
15:23:53 <bigbluehat> ... with the number of things going on, it can be helpful to see who's actually using this stuff
15:24:03 <bigbluehat> ... where can I see the W3C VC stack in the wild?
15:24:19 <bigbluehat> ... if you have or you know of an implementation of W3C VCDM, I'd be very interested to hear about that
15:24:33 <manu> q+
15:24:35 <wes-smith> wes-smith has joined #vcwg
15:24:37 <phila> ack manu
15:24:37 <bigbluehat> ... so we can jot some of that down and talk about them at the conferences this fall
15:24:53 <bigbluehat> manu: I can't mention all of our rollouts, but one of them is the CA DMV
15:25:16 <bigbluehat> ... all Driver's Licenses in CA are issued both as mDL and VCs
15:25:26 <bigbluehat> ... they also issue Vehicle Titles as only W3C VCs
15:25:36 <bigbluehat> ... there should be upcoming news about that
15:25:59 <bigbluehat> ... there has also been educationally focused VCs getting traction in CA
15:26:16 <bigbluehat> ... there are a number of pilots--such as the Career Passport pilot
15:26:40 <bigbluehat> ... MOSIP has mentioned that they have 180 million _people_ using VCs--obviously even more VCs than people
15:27:01 <bigbluehat> ... several US states are issuing VCs for a wide range of government and educationally related use cases
15:27:14 <dlongley> additional note on CA DMV: all new physical licenses include VCBs.
15:27:28 <bigbluehat> ... CONEXSUS and NACS are releasing several VC ecosystem-based deployments
15:27:32 <wes-smith> and ID cards!
15:27:40 <bigbluehat> ... I can't share all the timelines, but "soon"
15:27:50 <bigbluehat> ... some of this surfaces on https://vcplayground.org/
15:28:23 <bigbluehat> ... if you look at convenience.org's list of credentials, you'll find an entire retail store story there with VCs covering things such as gift cards, loyalty cards, etc.
15:28:39 <bigbluehat> ... and many more announcements coming in the next 6-9 months
15:28:48 <bigbluehat> phila: that's great data.
15:28:53 <michaelshea> q+
15:28:56 <phila> ack michaelshea
15:28:58 <bigbluehat> ... does anyone else have data they can share?
15:29:02 <pdl-ASU> I believe the California Career Passport also includes the Community Colleges and CA State University System, as well.
15:29:21 <bigbluehat> michaelshea: I believe the UNTP work is getting traction in Australia
15:29:32 <bigbluehat> ... and is moving from pilot to production in the next 12-18 months
15:29:41 <bigbluehat> ... that's obviously outside the person identity space
15:29:42 <manu> q+
15:29:52 <phila> ack manu
15:30:20 <bigbluehat> manu: thank you michaelshea, lots more going on at the UN and in the supply chain world as well
15:30:24 <pdl-ASU> ASU does issue W3C VC compliant OBv3 credentials as well
15:30:31 <bigbluehat> ... I also meant to call out VC Barcodes specifically
15:30:44 <bigbluehat> ... a VC Barcode is going on all physical Driver Licenses in CA
15:31:07 <bigbluehat> ... so VCs are in people's hands--with a 5-to-1 ratio opposite mDL technology in CA
15:31:07 <denkeni> q+
15:31:12 <phila> ack denkeni
15:31:28 <bigbluehat> denkeni: as manu mentioned, MOSIP has lots of adoption
15:31:44 <bigbluehat> ... we're going to propose a new task force under the CG soon
15:31:56 <bigbluehat> ... we're using much of this technology in our own countries
15:32:05 <bigbluehat> ... and I'm hoping we can contribute to test suites, etc.
15:32:19 <bigbluehat> phila: I believe there's also work going on in Brazil?
15:32:24 <denkeni> s/CG/CCG
15:32:47 <bigbluehat> Henrique: what I know is that there are biometric, non-VC-based private implementers
15:32:58 <bigbluehat> ... but the government is working on a solution based on verifiable credentials
15:33:27 <bigbluehat> ... I know VCs have been applied to giving credit to farmers, but not sure of the specifics
15:33:43 <bigbluehat> ... and for age assurance they are using VCDM
15:33:58 <bigbluehat> ... and also using the OID4* protocols
15:34:09 <bigbluehat> s/Henrique/hxavier
15:34:17 <bigbluehat> phila: anyone else have more to share?
15:34:34 <bigbluehat> ... I and many others are going to be on the road talking about our work and pushing their own approaches
15:34:44 <bigbluehat> ... it always helps to have real world use cases to present
15:34:47 <pdl-ASU> The Alabama Talent Triade is their statewide talent markplace has the W3C VC as a core pillar of its technology stack.
15:34:51 <bigbluehat> ... it provides confidence
15:35:04 <michaelshea> q+
15:35:05 <bigbluehat> ... and in this spirit, GS1 is indeed implementing W3C VCs
15:35:11 <kezike> kezike has joined #vcwg
15:35:21 <bigbluehat> ... we are a federated organization, so we have to work out governance next
15:35:40 <bigbluehat> ... also, for the Recognized Entity folks, we are planning to get our docs up to date to share with that task force
15:35:45 <bigbluehat> ... so, GS1 is certainly on board
15:35:46 <phila> ack michaelshea
15:35:53 <bigbluehat> ... which is a big deal for cross-border trade, etc.
15:36:05 <bigbluehat> michaelshea: there is a great deal of activity going on with UNTP
15:36:15 <bigbluehat> ... especially around mines
15:36:24 <bigbluehat> ... and pilots around fashion and textiles
15:36:33 <bigbluehat> ... and another around responsible businesses
15:36:58 <bigbluehat> ... there's also a seafood traceability group forming
15:37:09 <bigbluehat> ... and all these groups are bringing lots of attention to UNTP
15:37:20 <bigbluehat> ... and UNTP is 100% W3C VC based technology
15:38:17 <pdl-ASU> The Tennessee Board of Regents (TBR) through its CRED System (Comprehensive Record for Every Learner) uses VCDMs (via OBv3 and CLRv2s)to represent verified skills, course competencies, co-curricilar achievements and credit-for-prior-learning.

15:39:16 <bigbluehat> phila: great. I have nothing but respect for anyone working in standards
15:39:36 <bigbluehat> Elaine: and just so you know, folks often think I'm the liaison for the W3C--which I am not
15:39:46 <bigbluehat> phila: yes...similar confusions about around GS1 here
15:40:06 <brent> +1 Elaine should feel free to give ISO folks an update on what we're doing
15:40:07 <bigbluehat> ... michaelshea you wanted to discuss some specific things here
15:40:56 <pdl-ASU> The State of North Dakota issues W3C VCs to all K12 students (focused on middle and high school) and a few technical schools have joined into project managed through the State Longitudinal Data Service.

15:46:46 <bigbluehat> Subtopic: CID issue 166 https://github.com/w3c/cid/issues/166
15:48:25 <phila> bigbluehat: It's bc we're using content-based hashes, line endings and so on can change the hash. We have to look through until we find a match...
15:48:50 <phila> michaelshea: That's outside my expertise - can you help please?
15:49:30 <phila> bigbluehat: Has anyone gone through and checked all these? We may need to change how we share hashes so they don't get messed up.
15:49:34 <phila> q+
15:49:54 <phila> ack me
15:50:15 <bigbluehat> phila: there are a couple of instances where it really matters where the hash in the spec matches
15:50:24 <bigbluehat> ... I'm thinking the JSON-LD context file in the VCDM
15:50:29 <bigbluehat> ... in that case, it really matters
15:50:51 <bigbluehat> ... in the examples, I think I've seen text that says we make no cryptographic promises around examples
15:51:28 <brent> q+ to give context
15:51:36 <phila> bigbluehat: This is a topic in itself. Do we need non-normative hashes to be accurate?
15:51:41 <phila> ack brent
15:51:41 <Zakim> brent, you wanted to give context
15:51:51 <bigbluehat> brent: to give some context here...no pun intended
15:52:02 <bigbluehat> ... as we were preparing the last round of specs
15:52:03 <bigbluehat> q+
15:52:10 <dmitriz> @bigbluehat -- we really need to add a canonicalization attribute to digestMultibase..
15:52:17 <bigbluehat> ... we wanted to be able to normatively reference the context
15:52:33 <bigbluehat> ... I don't think removing the hashes is an option
15:52:40 <bigbluehat> ... we need to fix this one way or the other
15:53:00 <dlongley> dmitriz: i think that already exists, the group just didn't have consensus to use canonicalization for these hashes in the past.
15:53:17 <bigbluehat> phila: this maybe just needs a quick call with bigbluehat and pchampin
15:53:17 <dmitriz> @dlogley -- what's the mechanism? multihash?
15:53:25 <bigbluehat> michaelshea: I'm happy to try and set one up
15:53:38 <bigbluehat> phila: I know pchampin is on holiday
15:53:55 <bigbluehat> ... but basically, it's a bit of engineering to get it right
15:54:03 <bigbluehat> michaelshea: I will setup a separate call around 166
15:54:04 <dlongley> dmitriz: https://github.com/multiformats/multicodec/blob/master/table.csv#L595
15:54:42 <dmitriz> @dlogley -- I'm familiar with multicodec mechanism in general, I'm more asking -- does digestMultibase support that notation
15:54:57 <dmitriz> s/@dlogley/@dlongley/
15:55:30 <dlongley> dmitriz: yup, just use that header :) ... it's in the same namespace
