– DRAFT –
Dataset Exchange Working Group Teleconference

approve minutes of last meeting https://‌www.w3.org/‌2017/‌dxwg/‌wiki/‌Meetings:Telecon2018.02.20

Resolved: approve minutes of February 13

<kcoyle> https://‌www.w3.org/‌2017/‌dxwg/‌wiki/‌F2f3

<SimonCox> How about AUstralia?

<Makx> +1 to meeting minutes

<RubenVerborgh> at W3C in Boston? :-)

<SimonCox> We can host in Melbourne or Canberra any time

<antoine> I could try and see if we have rooms in The Hague (for free, at least the room...)

<SimonCox> No cost for meeting rooms in Melbourne or Canberra

<SimonCox> ... or Brisbane

kcoyle: sub group actions not in tracker automatically. any ideas?

<AndreaPerego> Need an action from Dave.

kcoyle: option - leave on github - open as question on mailing list?

<AndreaPerego> The current option we have is to create them manually after the meetings.

SimonCox: tension between w3C tracker and activity in github - some people not engaged via github
… open PRs - open several weeks - unable to report some actions because not yet processed on github - are people willing and able to use..

kcoyle: can we see actions?

SimonCox: doesnt have actions, but issues can be assigned

https://‌github.com/‌w3c/‌dxwg/‌issues/‌assigned/‌dr-shorthair

<DaveBrowning> Antoine

<DaveBrowning> Bingo

kcoyle: github activities gor to dxwg - so people signed up to github will see doubles - unwatch on github.

<SimonCox> To see all issues mentioning you, use https://‌github.com/‌w3c/‌dxwg/‌issues?q=is%3Aopen+mentions%3A{yourGitHubID}

<SimonCox> To see all issues 'assigned' to you, use https://‌github.com/‌w3c/‌dxwg/‌issues?q=is%3Aopen+assignee%3A{yourGitHubID}

kcoyle: one issue not responded to from Ana

roba: propose to respond - dcat profile subtypes not yet identified as a need - will emerge.

and ask for more details re other use cases

<antoine> there's already a template, no?

kcoyle: can someone start a respec template for profiles document and add agreed definitions

<annette_g> Hi folks, sorry I'm late

RubenVerborgh: template ready...

Action: RubenVerborgh paste profile definition into github document

<trackbot> Created ACTION-80 - Paste profile definition into github document [on Ruben Verborgh - due 2018-02-27].

* kcoyle: birds on agenda for F2F ;-0

kcoyle: agenda - aligning DCAT and ADMS...

<SimonCox> https://‌github.com/‌w3c/‌dxwg/‌issues/‌113

<alejandra> https://‌github.com/‌w3c/‌dxwg/‌issues/‌110

<SimonCox> https://‌github.com/‌w3c/‌dxwg/‌issues/‌53

<RubenVerborgh> Completed ACTION-80: https://‌github.com/‌w3c/‌dxwg/‌commit/‌6b9b800981a34bcb745031c5980f0f8acf856082

<alejandra> Makx's original issue about aligning with ADMS was related to the issue of removing domain/ranges

* simon - can you summarize that plz!

SimonCox: what are implications on ADMS for proposed changes on DCAT

<AndreaPerego> Just to note that adms:Identifier is also used in DCAT-AP.

Makx: developed in parallel to DCAT
… to describe "interoperability assets" - models, schemas etc
… W3C was a member of the EU working group
… Overlap with DCAT - ADMS was more specialised - decided ADMS was subclasses of DCAT
… some cross-fertilisation - e.g adms:contactPoint -> dcat:contactPoint
… cross between base standard and application profile

<SimonCox> (but no dependencies from DCAT to ADMS)

<SimonCox> ADMS does depend on DCAT

<SimonCox> ADMS rec is here https://‌www.w3.org/‌TR/‌vocab-adms/

<SimonCox> adms:Identifier class is here https://‌www.w3.org/‌TR/‌vocab-adms/#identifier

Makx: identifier was discussed - ADMS had microformat proposal
… but question is whether there is a need to upgrade ADMS

...Makx: volunteered at the time to take action to look at ADMS "in the future"

alejandra: good to look at solutions to inform - c.f. schema.org and lifesciences groups
… does it need to be in charter?

<kcoyle> roba: question for makx - do we know any other dcat specializations or extensions that are out there?

kcoyle: charter allows us to make "decisions we feel necessary?"

roba: is adms implemented widely - and what other dcat specialisations are they - and do we need to worry about.

<kcoyle> ?+

makx: 5-7 implemented using in EU context - if backwards compatibility and deprecation followed not a problem

SimonCox: need to be clear about scope: data exchange, new version of DCAT - dont see how group should be involved in revising other artefacts - worried about resources

<alejandra> yes, what Simon mentioned is what I was trying to say before - thanks

PWinstanley: UCR doc got "little traction" - so getting into BP territory for existing activities means possibly making dxwg less authoritative.
… link into EU projects - but rest of world - how do we touch them?

kcoyle: schema.org needs discussing - after DCAT gets further along - a big issue around discoverability

<AndreaPerego> PWinstanley, about reaching the scientific community world-wide, an option is to do this via RDA (Research Data Alliance).

Makx: multiple threads here - back to ADMS

<PWinstanley> mine is related to ADMS because there are EU projects, cataloguing data, that should be using ADMS/DCAT and they are not involved with us nor us with them

Makx: understand reservations - ADMS looking to DCAT

alejandra: ADMS source of information to extend DCAT

<PWinstanley> +1 to Alejandra

alejandra: learn from alignment (but outside our scope)

roba: can ADMS be recast as a profile of DCAT?

Makx: there is no ADMS community - problem with W3C not having a change and release policy...

<alejandra> ok, thanks for clarifying Makx

<Zakim> SimonCox, you wanted to report on how maintainenace of SSN is being handled

<AndreaPerego> -1 to create a new thing in DCAT replacing adms:Identifier

kcoyle: discussion focussed on identifiers - if we like would we use adms or create parallel DCAT property

SimonCox: dcat does not depend on ADMS - should retain this
… work on SSN rolled over from SDWWorkingGroup to SDWInterestGroup

SDWIG able to publish W3C notes - so extensions are non-normative but available

Makx: move to sub-group then report back

AndreaPerego: voted -1 because adms:identifier already used in DCAT-AP

<SimonCox> We can always say dcat:Identifier owl:equivalentClass adms:Identifier .

can it not also be made a subclass of dcat:identifier just as easily?

<kcoyle> https://‌github.com/‌w3c/‌dxwg/‌issues/‌131

SimonCox: changes being considered to dcat resources - e.g. dropping domain axioms
… are we changing semantics enough it is no longer the same thing - does it need a new namespaces?

<kcoyle> ?+

SimonCox: but issue is - is it the same thing, and do we need a new identifier. All but original poster is against new namespace as adoption barrier.
… so how much can we change and merit retaining URIs

kcoyle: does W3C have versions in namespaces?

SimonCox: some version designators - but this has now been largely discontinued - and old version numbers point to later versions of docs.

<AndreaPerego> FOAF is an example.

<SimonCox> SKOS also

Antoine: e.g. SKOS

Makx: not versioning namespaces, but version specifications

<SimonCox> We can version the specification, as implemented in an RDF file or graph

<SimonCox> but not the URI's for concepts whose semantics have not changed

<alejandra> about Maks' comment, we were calling the new DCAT document 1.1. while the issue we are discussing jumps to DCAT 2.0

Makx: does it break something?

<alejandra> this is a discussion we need to have too

<alejandra> but we are changing semantics, even if the changes are not so 'significant' at the moment

Makx: look at each case

<Zakim> SimonCox, you wanted to note that few implementations use reasoning

roba: can we publish DCAT1 profile of DCAT 2?

SimonCox: good idea :-)
… so who is reasoning over these axioms?

<Makx> ok thanks bye bye

<alejandra> I made the same point that roba made in the discussion in this issue: https://‌github.com/‌w3c/‌dxwg/‌issues/‌110

<LarsG> Thanks, bye!

<alejandra> thanks! bye

<PWinstanley> bye

<SimonCox> Roba: publish a dcat v1 profile that adds the v1 axioms back in

<kcoyle> AndreaPerego: I've gotten the minutes created - may not need your help this week ;-)
