2. VCWG at TPAC

Brent Zundel: https://www.w3.org/wiki/TPAC/2021/GroupMeetings

Manu Sporny: We have the ACLU that would like to engage, should I get back to them and invite? ^^^

Manu Sporny: That’s the “Americal Civil Liberties Union”

Brent Zundel: We have nothing on the TPAC agenda yet

3. Next VCWG Charter

Brent Zundel: https://w3c.github.io/vc-wg-charter/

Brent Zundel: charter has been updated to take into account all the comments from the last meeting
… we are now in a position to share it more broadly

Manu Sporny: Other deliverables is not clear enough yet. The scope of each one is unclear
… we should add a paragraph describing each one

4. Review PRs

Brent Zundel: https://github.com/w3c/vc-data-model/pulls

4.1. Making explicit the binding of the holder to a VC (pr vc-data-model#795)

See github pull request #795.

Brent Zundel: this is not errata but is making normative changes
… so it should be put in 2.0

Manu Sporny: I talked to Steven and he agrees that this PR should be removed and an issue raised to bring it into v2.0
… Steven has said he will close the PR after he has added this issue for v2.0

Brent Zundel: I am adding the defer v2.0 label
… now I would like to focus on v1.1 PRs

4.2. removes mention of termsOfUse with verifiable presentations (pr vc-data-model#787)

See github pull request #787.

Brent Zundel: summarised that ToU is said to be in presentations but this is not described properly. ie. there is a bug in the spec

Manu Sporny: approves the merge of this PR and it is after the 14 day review

4.3. Recode graph diagrams (pr vc-data-model#786)

See github pull request #786.

Manu Sporny: unfortunately the next time we update the diagrams it will overwrite the good changes the chaals did
… there is not a good solution to this because the diagrams are in google.docs but it does not support his changes

Manu Sporny: +1 to merge and face consequences

Manu Sporny: either it will be difficult to update the diagrams or difficult for some people to read them.

Brent Zundel: is anyone opposed to merging this now?

David Chadwick: There was no opposition so Manu performed the merge

4.4. Clarified subtitle of Data Model (pr vc-data-model#780)

See github pull request #780.

Brent Zundel: the current subtitle is not correct. but we dont have the perfect subtitle yet

Manu Sporny: I agree so we cannot merge yet

4.5. Vocabulary definition changes (pr vc-data-model#771)

See github pull request #771.

Brent Zundel: is this a breaking change or not? Should it be 1.1 or 1.2

Manu Sporny: non of the files that are touched are normative. Its only descriptive text. But if anyone was doing advanced graph processing then everything would break
… whilst it is safe to make the change now I would prefer to wait for 2.0 just in case someone is doing this advanced RDF processing
… this change does not affect implementors using JSON or JSON-LD processing, but only those doing graph processing

5. Issue Triage

David Chadwick: It was agreed to change the status of this to Defer to 2.0

Brent Zundel: https://github.com/w3c/vc-data-model/issues?q=is%3Aopen+-label%3A%22substantive+change+v1.2%22+sort%3Aupdated-asc+-label%3Av1.1+-label%3Adefer-v2

5.1. [PROPOSAL] New specification document title: W3C Consensus-based Data Model Specification for Verifiable Credentials (issue vc-data-model#791)

See github issue #791.

Brent Zundel: this is not a 1.1 or 1.2 issue, we should defer to v2.0

Manu Sporny: no W3C spec is titled consensus based, so it will never be accepted

Brent Zundel: Yeah, since the W3C process is consensus-based, this addition to the title would need to be added to all W3C specs
… and we don’t have enough folks here to make the decision anyway

Manu Sporny: I’m fine with us re-visiting this on a v2.0 timeframe.

David Chadwick: all standards are consensus based to the best of my knowledge

5.2. Explicit reference should be added about binding the VC to the holder (issue vc-data-model#789)

See github issue #789.

Manu Sporny: +1 to defer v2

Brent Zundel: this should be defer to v2.0

David Chadwick: +1

5.3. [PROPOSAL] Spec needs to include a non-JSON/non-JSON-LD example VC binding e.g. JPEG EXIF/XMP (issue vc-data-model#796)

See github issue #796.

Manu Sporny: Suggest deferring to v2.0

Brent Zundel: whilst no-one objects to this principle, this is out of scope of our current charter

5.4. V1 specification doesn’t definitively state that the credentialSubject.id, if specified, is always the id of the Subject of the Credential (issue vc-data-model#792)

See github issue #792.

Manu Sporny: https://github.com/w3c/vc-data-model/issues/792#issuecomment-900283929

Brent Zundel: this editorial change could fit into v1.1

David Chadwick: Part of the issue is bearer VC – understanding who it’s attached to – nobody, everybody, etc.
… I don’t think it covers the “no holder” use case… we should write about “if not specified”.

Brent Zundel: Let’s do a separate issue for that

Manu Sporny: yes, please.

5.5. [PRINCIPLED OBJECTION] The VC data model specification 1.0 is not implementable in the ways it appears to be intended based on the text of the current specification document (issue vc-data-model#797)

See github issue #797.

Brent Zundel: no PR has been raised to address this issue, so no resolution is currently available

Manu Sporny: we have to record this objection unless the author takes it back.

Brent Zundel: the issue must remain open until some action is taken

6. v1.1 issues

Brent Zundel: https://github.com/w3c/vc-data-model/issues?q=is%3Aissue+is%3Aopen+label%3Av1.1+sort%3Aupdated-asc

6.1. Examples issuanceDate is invalid (issue vc-data-model#736)

See github issue #736.

Brent Zundel: https://github.com/w3c/vc-data-model/issues/736

Manu Sporny: this has been addressed by 737 so it should be closed now

6.2. Bug in the credential vocabulary specification (issue vc-data-model#770)

See github issue #770.

Brent Zundel: https://github.com/w3c/vc-data-model/issues/770

Manu Sporny: +1 to defer v2

Brent Zundel: label this defer to v2.0

6.3. Some example credential types not defined in example context (issue vc-data-model#750)

See github issue #750.

Brent Zundel: https://github.com/w3c/vc-data-model/issues/750

Brent Zundel: there is a PR that has been merged to cover this

Manu Sporny: DavidC: We should take the same approach for all of them.

Manu Sporny: we should have put the word example in front of all these and added them to the example @context

Brent Zundel: is anyone opposed to closing this particular issue?

David Chadwick: none

Brent Zundel: i will email everyone with proposed meeting times
