RiccardoAlbertoni: request to add specific section, and I have drafted a pull request (early draft)

Link to relevant section: https://raw.githack.com/w3c/dxwg/dcat-issue-1358/dcat/index.html#accessibility

RiccardoAlbertoni: Matches what was asked for (superficially) - but should we go further
20:14:31 [DaveBrowning]

DaveBrowning: Concerned that we will need to do something in the examples
20:23:58 [DaveBrowning]
RiccardoAlbertoni: They have only really asked for something equivalent to what we did for Security etc
20:24:27 [DaveBrowning]
alejandra: we probably need to go back to them for a bit more guidance/clarification
20:25:11 [DaveBrowning]

AndreaPerego: We already have descriptions (textual) for some of the URLs(e.g for distributions) in the metadata....
20:28:37 [alejandra]
adding some other of my comments from before - perhaps we could consider a new property on the distributions for the alternative text
20:29:21 [alejandra]
... but as the issue is around a section at the same level of Security and Privacy, perhaps they want us to raise awareness of data accessibility by mentioning it, as Riccardo did in the proposal
20:31:35 [AndreaPerego]
action: RiccardoAlbertoni to ask for feedback in https://github.com/w3c/dxwg/issues/1358 on accessibility section

RiccardoAlbertoni: Some discussion on changing the range of dcat:theme
20:33:07 [RiccardoAlbertoni]
see example, in the Revhttps://www.w3.org/TR/2009/REC-skos-reference-20090818/#L896
20:33:50 [AndreaPerego]
s/in the Rev/in /
20:34:22 [DaveBrowning]
... some concern that even if allowed by REC that we are putting as object both instance and class
20:34:33 [alejandra]
+q
20:34:33 [DaveBrowning]
... not clear on the impact
20:34:53 [RiccardoAlbertoni]

20:36:08 [DaveBrowning]
RiccardoAlbertoni: 2 possible solutions - either use owl classes as object or alternatively use union of skos concept and owl class...
20:36:27 [DaveBrowning]
... could be useful to clarify that both could be expected
20:36:55 [RiccardoAlbertoni]
q?
20:36:55 [AndreaPerego]
I think this issue is more or less about the same point: https://github.com/w3c/dxwg/issues/1362
20:37:54 [DaveBrowning]
alejandra: Interesting issue. We do need to clarify. If we allow owl classes then we need to explain that its okay by usage note or other comment
20:39:03 [DaveBrowning]
... discussion on dcterm:subject is also relevent. (History of the evolution of DC is kind of lost)
20:39:22 [RiccardoAlbertoni]
q?
20:39:25 [DaveBrowning]
... Need to make this clear
20:39:26 [RiccardoAlbertoni]
ack AndreaPerego
20:40:56 [DaveBrowning]
AndreaPerego: Yes, it needs to be clarified. Looking at how its used - theme tends to be thematic 'environment'; 'public sector', essentially the main topic
20:41:27 [DaveBrowning]
... Generally we try to be inclusive and different groups do different things
20:42:04 [DaveBrowning]
... They have their own ways and we risk creating confusions.
20:43:08 [DaveBrowning]
... Could include owl individuals, but as said - people are using DCAT as owl ontology, but although we do use owl DCAT wasn't designed to be used like that
20:43:41 [DaveBrowning]
... A lot of these issues could be resolved via SHACL or profile ...
20:44:37 [DaveBrowning]
... We do have conficting issues raised
20:45:25 [DaveBrowning]
... Different communities pulling in different directions
20:46:02 [DaveBrowning]
RiccardoAlbertoni: People are confusing that range: is really guidance not a constraint

RiccardoAlbertoni: To summarise - is the feeling that we should explain more?
20:48:55 [DaveBrowning]
AndreaPerego: We risk upsetting one party if we change/say anything, so we need to something more

20:57:10 [alejandra]
so, is this a bug? https://github.com/w3c/dxwg/blob/836b201802c0859c20bd066816e0c2cebb239f12/dcat/rdf/dcat3.ttl#L1034

Issue about dc:subject and dcat:keyword: https://github.com/w3c/dxwg/issues/175
20:59:50 [DaveBrowning]
RiccardoAlbertoni: So looks like the ttl needs fixing.
21:00:33 [DaveBrowning]
... What should we be adding to the examples to explain?
21:00:58 [DaveBrowning]
alejandra: I'll raise an issue for the errata
21:02:16 [DaveBrowning]
RiccardoAlbertoni: I'll put together a draft for the clarification and we can review. Key is we don't want to change the range of dcat:themes
21:02:21 [DaveBrowning]
... yet

21:06:30 [DaveBrowning]
AndreaPerego: Part of the idea was to see if people would want to collaborate on alignments, but not in the standard. Do we want an 'official' place?
21:07:00 [DaveBrowning]
RiccardoAlbertoni: Might be a good idea. github wiki or W3C?
