Content:

1. Agenda Review

David Ezell: No requests.

2. Reintroductions

David Ezell: I’m David Ezell, work for a trade association called Conexxus, and work closely with National Association of Convenience Stores (NACS). I’m not a cryptography expert, but care very much about availability of these technologies and application to our work. I’ve been at W3C for 23 years.

3. Next Topic Call

Brent Zundel: 6PM today eastern. DID core properties and metadata.

4. Extended call in June

Brent Zundel: Seems like the week of June 29 - July 3 works well for being able to have some additional meetings.
… watch for a doodle poll.
… each block will be about 90 minutes, with a break of 90 minutes, over the course of 3 or so days.
… we hope people will give these meetings precedence.

Daniel Burnett: In other words, it’s not a face-to-face but should be given the same priority

Brent Zundel: it will be hard to replicate a face to face, but we’ll do our best.

Drummond Reed: just trying to get a feel…

Brent Zundel: June 29 is only 4 weeks away.
… doodle poll should be out this week.

5. registries document status

Brent Zundel: expecting to publish a FPWD note soon. [scribe missed the antecedent]

Manu Sporny: +1 to publish FPWD of DID Specification Registries document!

Manu Sporny: DID Specification Registries FPWD NOTE

Manu Sporny: https://w3c.github.io/did-spec-registries/

Drummond Reed: Many thanks to both Orie and Amy for their work on this (and Manu too, but Manu’s everywhere ;-)

6. Editors’ issues

Manu Sporny: a couple of PRs - especially CBOR.
… there’s a question about what to do with the PR… pull into spec?
… if we do that I’d like a huge warning (experimental).
… we’re in a weird place - trying to finish with new things coming in.
… there is some misalignment with what to do with that section.
… So, editors’ intention is to pull in the section with a big warning, and we’d like to know how the group feels about that.
… we’d also like Jonathan to know that the section >may< come out of the spec if it meets with disagreement from review.

Jonathan Holt: would appreciate more eyes on this part of the spec.
… what’s in the PR, it’s moving toward “DAG” CBOR (IPID).

David Ezell: [scribe not familiar with terminology]

Jonathan Holt: CBOR allows integers, be we constrained to strings.
… this offering is NOT CBOR-LD.
… the core data model is not quite mature, and we’ll have a better idea of what can be extended with experience.

Ivan Herman: normally we could call this a “feature at risk” signaling that it might be removed.
… while this kind of thing is good in a near-final publication, ie, CR, it feels out of place in a WD.

Justin Richer: it feels like “fear mongering” to be too strong with our worries about the section.
… I think the section belongs without the warning.

Daniel Burnett: we don’t need to out that label on today. There is plenty of time (before end of candidate recommendation) when we need implementation reports from two implementors.

mike: I agree it should go in, with no warning.

Manu Sporny: I will then merge it in with no warning. I have a worry that I don’t know of any implementor planning to use CBOR.

Orie Steele: I’ve also not seen a single company this committed to “Pure JSON”, so…. same thing applies to that.

Manu Sporny: we could spend a lot of time working on a feature with no second implementer.
… there are a few change suggestions. Jonathan, please review, and let us know.

Jonathan Holt: will do.

Daniel Burnett: Good point Orie

Manu Sporny: Amy put in editorial PRs that deserve review.
… since Jonathan won’t be able to make the special call today, we’ll put that discussion on hold.
… we have other requests we’ll talk about on the special call later today.

Daniel Burnett: any other editors’ issues?

7. Core issues’ status checks

Daniel Burnett: https://github.com/w3c/did-core/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-asc

Drummond Reed: I’m working on the terminology section - please send me notes.

Daniel Burnett: https://github.com/w3c/did-core/issues/176

Daniel Burnett: last comment was Mike said he would reread and comment. Any update.

mike: please skip.

Daniel Burnett: https://github.com/w3c/did-core/issues/205

Daniel Burnett: from Justin. Any update?

Justin Richer: sorry I haven’t been keeping up. We need to pick something. Consistent across representations.
… We need to define “if you see a property you don’t understand, what should you do?”
… JSON systems tend to ignore such properties.

mike: I thought there was already a statement saying unknown properties MUST be ignored.

Justin Richer: I put in text, but it’s only one possible solution.

Daniel Burnett: this is a status check only, don’t want to go to deeply.
… those interested please go put your opinions in the issue and then we can decide whether to schedule more discussion.

mike: don’t we already have text that says unrecognized members should be ignored. What’s the issue?

Justin Richer: I want to be sure that is the will of the group.

Daniel Burnett: we’re still working on it. Text that has been discussed thoroughly has a higher bar for change.

Daniel Burnett: https://github.com/w3c/did-core/issues/176

mike: I need to create a PR - I haven’t worked on it yet.

Daniel Burnett: https://github.com/w3c/did-core/issues/199

Brent Zundel: status started with a question that turned into a broad discussion. A lot of suggestions, including [scribe missed] changes to the document. PR needs to be created.

Drummond Reed: I will work with Brent on this PR.

Daniel Burnett: https://github.com/w3c/did-core/issues/154

Oliver Terbu: I think Orie should give the comments.

Orie Steele: we went over the did registry property definitions, and have made changes that should be reviewed.
… we’re ready to make progress so review should happen soon.

Daniel Burnett: you had said progress was blocked by the registries discussion, so what is the exact status?

Jonathan Holt: I struggled to use the “proof” section of the document in the CBOR section.

Amy Guy: jonathan_holt - there’s a PR to remove proof.. if that helps?

Jonathan Holt: this is where I need some guidance.

Daniel Burnett: is that a question for this issue, or is it a broader question for the group?

Jonathan Holt: I think LD proof need not to be the only proof mechanism, and I’ll work on that.

Amy Guy: jonathan_holt, see https://github.com/w3c/did-core/pull/305

Daniel Burnett: https://github.com/w3c/did-core/issues/198

marcus: several iterations of PRs, see 295-300 (PRs).
… function definition for resolution, my opinion is that we should merge one (296?)

Justin Richer: In order: https://github.com/w3c/did-core/pull/295 https://github.com/w3c/did-core/pull/296 https://github.com/w3c/did-core/pull/297 https://github.com/w3c/did-core/pull/298 https://github.com/w3c/did-core/pull/300 https://github.com/w3c/did-core/pull/299

Daniel Burnett: please add the other references.

Daniel Burnett: https://github.com/w3c/did-core/issues/236

Orie Steele: https://w3c.github.io/did-spec-registries/#publickeyhex

Manu Sporny: the registries discussion is leading to more work. Public Key hacks will go into the document. Orie, where will we point from the registry?

Orie Steele: we may end up with a big bucket in git.

Manu Sporny: we’ll put that in the issue.

Orie Steele: yes :)

mike: we’re not just defining terms, we’re describing the semantics of the identifier and how it’s used.

Orie Steele: I agree

Daniel Burnett: https://github.com/w3c/did-core/issues/118

Amy Guy: burn, I put in a comment for current status

Daniel Burnett: Amy, we need to conform to Accessibility guidelines, but we need an initial review request.

Amy Guy: burn, I don’t know anything about asking for review, I’m just working through the self checklist

Daniel Burnett: I’m asking about the self-review beginning horizontal review.

Daniel Burnett: https://github.com/w3c/did-core/issues/260

Drummond Reed: I think the issue of “more than one controller” is related to “DIDs being identified.” Therefore I’ll put my name on this issue.

Daniel Burnett: https://github.com/w3c/did-core/issues/178

Yancy Ribbens: I haven’t started considering this issue.

Daniel Burnett: do you understand what needs to happen?

Yancy Ribbens: I have in mind the needed wording, but haven’t done anything yet.

Daniel Burnett: could you just put a quick idea of what you intend in the issue.

Daniel Burnett: https://github.com/w3c/did-core/issues/195

Manu Sporny: there is on-going discussion about whether or not what verification methods are authorized to do updates, and should that be in did-core or did methods.
… IMO did methods will have to specify what verification methods can operate on a DID document.

Daniel Burnett: yes, we still have to establish the rules.

Daniel Burnett: https://github.com/w3c/did-core/issues/8

Daniel Burnett: my name is on here, along with Brent and Mike.
… anyone like to offer an opinion?

Orie Steele: verification methods are often a function of the upper level type attribute.
… I’m not in favor of adding any language.

mike: public key JWK should be a self-contained description - that was the issue.

Daniel Burnett: doesn’t seem there’s agreement - so we need a call.
… “needs special call”. I’ll remove “discuss”. Needs to be flagged as needing more than just comments in the issue.
… removing myself and brent, since we were only there because we needed a call, and we have a method for that

Justin Richer: That is what the last comment says, though – just fwiw

Daniel Burnett: https://github.com/w3c/did-core/issues/85

Daniel Burnett: we haven’t had a comment for a month. Marcus please add.

Justin Richer: says it’s addressed in PR 253. Marcus please add that, too.

Daniel Burnett: https://github.com/w3c/did-core/issues/14

Daniel Burnett: Christopher, Daniel, Oliver assigned…
… looking for someone to give a status.

Orie Steele: is joe here?

Orie Steele: this is mostly blocked by his comments afaik…

Orie Steele: mike has a PR request not to allow revoked keys, and I’ll follow up.

Daniel Burnett: time to bring this one to a close.

mike: what’s the status of merging the PR to address?

Manu Sporny: it’s merged, but people are saying it didn’t address the issue.
… Joe didn’t respond, so I merged, but now it seems insufficient.

Dave Longley: there was a simple suggestion that was not pulled in.

Daniel Burnett: Dave and Mike please address in the issue.
