<alejandra> ... to see how distribution is misused sometimes

<alejandra> ... including very different types of content

public comments

alejandra: did not receive it

alejandra: talking about Guillaume Duffes email - https://‌lists.w3.org/‌Archives/‌Public/‌public-dxwg-comments/‌2018Sep/‌0000.html

SimonCox: about versioning issue

SimonCox: I was aproached by contacts from a versioning WG

alejandra: talking about action https://‌www.w3.org/‌2017/‌dxwg/‌track/‌actions/‌187

DaveBrowning: how do we engage these people?

SimonCox: both side waiting for activities on other side..

SimonCox: the UCs are fine as they are at moment

<Zakim> AndreaPerego, you wanted to comment on the RDA Data Discovery Paradigm group & schema.org

SimonCox: but a separate task group may want to derive more details

<AndreaPerego> About the RDA DDPIG post on schema.org task force: https://‌www.rd-alliance.org/‌group/‌data-discovery-paradigms-ig/‌post/‌rda-ddpig-task-force-using-schemaorg-research-dataset

AndreaPerego: there is a Data Discovery Paradigm (DDI?) group

AndreaPerego: engaged to report about DXWG work

AndreaPerego: ther might be an misunderstanding about indexing metadata

AndreaPerego: Google e.g. considers (a subset of) schema.org

AndreaPerego: elaborated models will not be considered by search engines, there is a movement towards schema.org

alejandra: regarding versioning, will there be a separate task force?

DaveBrowning: I'd avoid an additional meeting

DaveBrowning: no plans so far, we should colect resources available and provide as input to interested audience

DaveBrowning: I will provide a strawman proposal

alejandra: when we'll release the 2nd WD, we are not clear about which parts of DCAT are indexed by Google

<alejandra> From the public comment "Note 5 / Issue #98: The subtyping relationship between dctype:Dataset and dcat:Dataset has been removed. Although the subtype was indeed too restrictive, should another relationship not be added to characterise the relationship between both and leave the user helpless?"

alejandra: comming back to public comments

alejandra: what is in the DCAT v.2014 w.r.t to this comment?

<alejandra> alejandra: would it be a profile of dcat2014 w.r.t to the revised DCAT?

SimonCox: talk to Nick about developments on DCAT profiling mechanism

<alejandra> a?

alejandra: the commenters is requesting how to deal with the removal of this relationship?

SimonCox: the issue is not really obvious

<alejandra> This is the issue: https://‌github.com/‌w3c/‌dxwg/‌issues/‌98

SimonCox: the subtyping was felt too restrictive

SimonCox: how do now relate the dcat:Dataset and dct:Dataset?

<alejandra> SimonCox: suggesting to point to https://‌w3c.github.io/‌dxwg/‌dcat/#classifying-dataset-types

SimonCox: dct:Dataset would apparently go into dct:type

SimonCox: comparing the definitions of both concepts, DCT seems to align with 2014 DCAT definition

<SimonCox> dctype vocabulary is mentioned in https://‌w3c.github.io/‌dxwg/‌dcat/#classifying-dataset-types

<alejandra> Jaroslav_Pullmann: SimonCox

<alejandra> Jaroslav_Pullmann: SimonCox pointed out to dct:type

<alejandra> ... predicate to point to more specific types of dataset

<SimonCox> otherwise the question is how to compare the definition of dataset from here http://‌dublincore.org/‌documents/‌dcmi-terms/#section-7 i.e. "Data encoded in a defined structure." with the definition from https://‌w3c.github.io/‌dxwg/‌dcat/#Class:Dataset i.e. "A collection of data, published or curated by a single agent, and available for access or download in one or more formats."

SimonCox: we indicate removal of the predicate but do not give the explanation

<SimonCox> Maybe we should expand this note "NOTE In DCAT 2014 [VOCAB-DCAT-20140116] dcat:Dataset was a sub-class of dctype:Dataset, which is a member of the DCMI Types vocabulary [DCTERMS]. This relationship has been removed in the revised DCAT vocabulary - see Issue #98." to explain why the change was made

Action: SimonCox: clarify this in document

<trackbot> Sorry, but no Tracker is associated with this channel.

<DaveBrowning> and explain that his email got lost....

alejandra: we create an issue and address the issue by a pull request/update of the document

<alejandra> Second point: 11 DCAT Profiles, Issue 72, "for spcific applications" --> "for specific applications"

<alejandra> Already fixed

<alejandra> Third comment about https://‌github.com/‌w3c/‌dxwg/‌issues/‌88

alejandra: responded to comment within the issues which is still under discussion

alejandra: mapping to DDI

<alejandra> Last comment about DDI and Disco relationship

<alejandra> should we include it in https://‌github.com/‌w3c/‌dxwg/‌issues/‌164 ?

Action: alejandra to add comment on issue 164

<trackbot> Sorry, but no Tracker is associated with this channel.

Action: alejandra to reply to the comment list

<trackbot> Sorry, but no Tracker is associated with this channel.

Second Working Draft - issues, progress, owners

2nd public WD

alejandra: decision when to finish - mid September?

<DaveBrowning> https://‌rawgit.com/‌w3c/‌dxwg/‌dcat-demo-daveb/‌dcat/‌index.html

DaveBrowning: had some coversaions with Dave Raggett

DaveBrowning: there is new PWD header

linking to the previous version and linking to the recommendation

DaveBrowning: we need to make a proposal how to publish the RDF

at moment the document links to the live ontology on github

DaveBrowning: we should link to a stable version

DaveBrowning: Dave done some (link) checks already

alejandra: need to close editorial issues (e.g. link to old version of RDF)

alejandra: what is going to be the final URL?

DaveBrowning: W3C will link to a latest dated snapshot

<alejandra> https://‌www.w3.org/‌TR/‌vocab-dcat-2/ will always point to the latest

<Zakim> SimonCox, you wanted to ask if we could create a 'tag' in GitHub, and point to the RDF at the tag

SimonCox: what is the problem exactly?

<alejandra> This issue: https://‌github.com/‌w3c/‌dxwg/‌issues/‌320

<alejandra> Milestone: https://‌github.com/‌w3c/‌dxwg/‌milestone/‌13

alejandra: we should resolve the "editorial" issues in the recent milestone

alejandra: should we move the publication to end of September?

DaveBrowning: agree, need to clarify with Dave R. how to publish the RDF

alejandra: some of the issues would need to be removed - since still to be discussed

alejandra: should focus on document improvements

SimonCox: should we finalize by end of next week?

alejandra: yes, in order to meet the deadline by end Sept. It's not going to be complete

<SimonCox> +1

alejandra: progress on issues until next week, make decision then

DaveBrowning: the issues have various complexity

DaveBrowning: we should early tidy up

alejandra: should we as group decide upon issue inclusion?

SimonCox: if there is no pull request - there is no solution, need to separate them out by next week

alejandra: we'll keep the discussion until next week

DaveBrowning: should I proceed in terms of an RDF snapshot?

alejandra: definitely, we need a stable version (tag on github)

<SimonCox> +1 DaveBrowning `

<AndreaPerego> Thanks, bye bye
