Conneg current position

PWinstanley: has there been any publicity? any feedback?

roba: TomB & Fung

PWinstanley: checked if W3C does a media release - answer no
… so has written a blog item
… to get put into W3C blog
… at PriceWaterhouse last week, looking at public service vocabularies

<AndreaPerego> It would be important also to announce it on the public-comments mailing list.

PWinstanley: there is interest there too.

Action: PWinstanley to check if an announcement has been made to public comments list

<trackbot> Created ACTION-329 - Check if an announcement has been made to public comments list [on Peter Winstanley - due 2019-05-28].

DCAT status

<PWinstanley> https://‌www.w3.org/‌2002/‌09/‌wbs/‌99375/‌DCAT_PR/‌results

PWinstanley: poll to move DCAT2 to PR - current status 16 +1s - plh_ agrees OK to proceed on that basis

DaveBrowning: a lot of purely editorial work on document in last couple of weeks - shout out to AndreaPerego in particular
… we have not focussed on implementation evidence yet.

plh_: correction - next status is Candidate Rec (not Proposed rec)
… CR must show substantive issues are resolved, and level of wide review from the community

<plh_> Internationalization, Privacy, Security, Shape Expressions CG, SHACL Community Group, schema.org for datasets Community Group, ODRL Community Group, European Commission's ISA Programme, Research Data Alliance, and bioCADDIE WG 3.

plh_: posted list of groups that should be pinged

AndreaPerego: ISA has been informed

<annette_g> Dan Brinkley from schema.org has been involved in DCAT a bit.

AndreaPerego: RDA AndreaPerego and SimonCox are members
… DanBri is member of DXWG
… alejandra represents BioCaddie

plh_: since this is a revision, then some considerations carry over.
… internationalization, privacy
… depends on the nature of the actual changes

<PWinstanley> SimonCox: ON the shape expressions and SHACL groups, there was intention to do things in that space, but we have not done so - so is involvement of them still relevant?

SimonCox: since we have not used ShEx or SHACL do we need to consult with those groups?

<TomB> I think the ShEx CG could be interested if we understand what is being requested

annette_g: we should be as wide ranging as possible - solicit feedback anyway

<TomB> not a question

<TomB> If the request is clear, I think ShEx CG would be interested in engaging

<PWinstanley> SimonCox: What should we ask of the community groups?

plh_: "we believe the spec is ready; do they have any comments before we move ahead?"

Action: DaveBrowning to formally notify these CGs with plh_ -style request

<trackbot> Created ACTION-330 - Formally notify these cgs with plh_ -style request [on David Browning - due 2019-05-28].

plh_: recommend new PWD including the latest changes

<plh_> https://‌www.w3.org/‌wiki/‌DocumentReview#TL.3BDR

Action: plh_ to progress new PWD

<trackbot> Error finding 'plh_'. You can review and register nicknames at <https://‌www.w3.org/‌2017/‌dxwg/‌track/‌users>.

DaveBrowning: privacy group has done questionnaire

<roba> SheX and SHACL are not affected by DCAT - but there is an issue of how to link constraints models they express to the concepts that datasets conform to - profiles provides a "wrapper" to enable that.

Proposed: release new PWD of DCAT2

<TomB> roba, good point - it is not clear to me what aspects of DCAT the ShEx CG would want to review

Resolved: release new PWD of DCAT2

<antoine> +1

AndreaPerego: one last ed fix before plh_ action
… subtitle - currently "Revised edition" - should it be "Version 2"?

see https://‌w3c.github.io/‌dxwg/‌dcat/

<roba> * i have to run in a few moments :-( - info is profiles vocab undergoing implementation and review in ODRL, OGC and LOCI projects anyway - feedback on conneg doc points to some further improvements making clear that "profile" is "relative" to where you start, and all specifications can be viewed as profiles.

Proposed: subtitle should say "Version 2"

Resolved: subtitle should say "Version 2"

<AndreaPerego> Relevant PR: https://‌github.com/‌w3c/‌dxwg/‌pull/‌938

Action: AndreaPerego to make change subtitle should say "Version 2"

<trackbot> Error creating an ACTION: could not connect to Tracker. Please mail <sysreq@w3.org> with details about what happened.

Or should it be "Second Edition"? like OWL, XSD ...

PWinstanley: we previously agreed to not be precious about version numbers and expect them to accelerate with 'evergreen' status

<roba> * off - may get back before end of hour..

PWinstanley: any more on DCAT?

TomB: unclear that ShEx CG would have any real comments

AndreaPerego: asks plh_ how to assemble implementation evidence
… varies widely for vocabularies ...
… e.g. tests that vocabs are being used 'validly'
… demonstrate use in other contexts
… in particular who is using the parts of the vocabulary that are part of the _changes_

AndreaPerego: timing?

plh_: at least 4 weeks, + wide review
… group charter ends at end of June
… need to request an extension
… 3 or 6 months? How much do we need?

Do we need an extension for DXWG?

plh_: even with an extension, will it be long enough for Profile Guidance?
… might need a new charter?

PWinstanley: release Profiles Vocab as a WG note for now, then new WG (new charter) for Profiles as rec

<Zakim> TomB, you wanted to ask whether we are talking about Profile Guidance or Profile Vocabulary?

PWinstanley: clarification - the chartered deliverable is Profile Guidance.
… which is a long way behind and unlikely to be delivered in 3 months - due to 'northern summer'

PWinstanley: current status of Profile Guidance document?
… work is still rather amorphous

<TomB> +1 that the document is fairly amorphous (ie, would need alot of work)

<annette_g> +1 to TomB

antoine: profiles guidance work was put on hold

PWinstanley: DCAT and Conneg do not depend on profiles work

<roba> * back

<Zakim> TomB, you wanted to say that conneg and dcat seem quite separate from the Profiles Guidance and Vocabulary - could go to Recommendation without dependence on Profiles Vocab/Guidance

PWinstanley: perhaps we should recognize that the profiles work will only be a distraction from delivering DCAT and Conneg
… and separate/defer it.

<annette_g> (my +1 was for TomB's opinion that profiles guidance should be published along with other profiles docs)

TomB: there is no difficulty to move forward with DCAT and Conneg, as long as any cross-references to profiles work is disentangled from with the documents

<TomB> +1 to focus on Conneg and Dcat

antoine: yes, DCAT can be extracted
… however, Conneg needs to answer the question "what is a profile" by itself.
… rather than refer to defs in Profiles guidance

roba: most comments relate to question of 'what is a profile'. Examples needed, which we all agree on.
… We should also be able to issue Profiles Vocab as a "Note" to encourage and support use

<TomB> +1 to antoine - that Conneg could answer the question "what is a profile" by itself - ideally, this would be done in Guidance, but not essential - could be done in Conneg

roba: no resources have been committed to "Guidance" document yet
… Profiles negotiation is incomplete without a clear explanation of what a profile is

PWinstanley: can we write a short ("low fat") document or section that explains what a profile is?

roba: profiles vocabulary does this - 3 classes, a few axioms

PWinstanley: can 'what is a profile' be extracted from this? Profiles _vocabulary_ implementation is not needed for definition.

roba: Don't know. Difficult without a formalism. Vague words don't cut it.
… profiling is a relative process - tends to depend on where you start. Is DCAT a 'profile' of RDF, for example ...?
… "Profile" is highly contextual - what looks like a profile to one person might not to another.

PWinstanley: what extension do we need for DWXG? 3 months likely insufficient to complete DCAT and COnneg safely, given seasonal constraints upcoming.

<Zakim> TomB, you wanted to ask for confirmation that Profiles Vocabulary, if pursued, would be a Note

proposed: DWXG request a 6 months extension, during which DCAT and COnneg will be completed, and decisions will be made concerning the future plans for the Profiles work

SimonCox: ask for clarification - already agreed that Profiles Vocab would be issued at Note at some stage, but not sure if under current charter etc.

PWinstanley: thanks all for hard work
