Update metadata of the RDF definition of DCAT3 #1508

andrea-perego · 2022-05-12T21:35:50Z

Some of the metadata of the RDF definition of DCAT3 are not up to date, and some are missing.

As a first proposal, the following revisions have been included in this PR:

added preferred namespace URI & prefix
added version information
added DXWG as dcterms:creator
added rdfs:isDefinedBy where missing
added foaf:depiction to link to the DCAT3 diagram
added dcterms:created & dcterms:issued
added dcterms:title & dcterms:description
added dcterms:publisher
updated the list of contributors / authors / editors to align them with the specification, as decided in https://www.w3.org/2022/05/17-dxwgdcat-minutes#t04 - commit c1c1018
added translators, as decided in https://www.w3.org/2022/05/17-dxwgdcat-minutes#t04 - commits 9d1fea9 , 9b7afca

The proposal includes also some editorial and bug fixes:

re-ordered alphabetically properties used in the definition of classes and properties
fixed bugs in the definition of dcat:resource to align it with the specification, and added Italian translation
added rdfs:subPropertyOf where missing, to align the RDF definition with the specification

@plehegar , in the RDF definition of DCAT3 we specified W3C as publisher,:

dxwg/dcat/rdf/dcat3.ttl

Line 117 in 9d1fea9

dcterms:publisher <https://www.w3.org/> ;

The question is whether it is fine we use https://www.w3.org/ as the URI for W3C - as far as I know, there is no RDF description associated with it, or embedded in the corresponding HTML page.

In other words, which is the "official" URI to be used when referring to W3C in an RDF graph?

https://www.wikidata.org/entity/Q37033 This has tons of useful rdf factoids nearby!

I notice that https://www.w3.org/ uses content-negotiation, so adding an RDF "view" of it would probably be feasible?

NB: if we did that, we would still need to distinguish the web-page (https://www.w3.org/) from the organization (https://www.w3.org/#this).

I have implemented the changes discussed in the last DCAT subgroup meeting (see https://www.w3.org/2022/11/29-dxwgdcat-minutes).
To be consistent with the resolution (https://www.w3.org/2022/11/29-dxwgdcat-minutes#r04), we do not distinguish between the web page (https://www.w3.org/) and the organisation (https://www.w3.org/#this).

@pchampin: Do you still think that distinction is pivotal?

@pchampin: Do you still think that distinction is pivotal?

It really depends on who is going to consume that RDF metadata, and how pedantic they will be about it. In order to be future-proof, I would refrain from conflating the webpage and the organization. I'll make a suggestion in my review.

pchampin

I made suggestions on the TTL version only. The corresponding changes should be made on the RDF/XML and JSON-LD version as well...

dcat/rdf/dcat3.ttl

pchampin · 2023-01-09T15:47:21Z

dcat/rdf/dcat3.ttl

-  dcterms:modified "2022-05-12"^^xsd:date ;
+  dcterms:modified "2022-05-23"^^xsd:date ;
+  dcterms:modified "2023-01-05"^^xsd:date ;
+  dcterms:publisher <https://www.w3.org/> ;


This is conflating a web page and an organization. As we don't have, currently, a nice IRI identifying the organization, I think the easiest path we have is this:

Suggested change

dcterms:publisher <https://www.w3.org/> ;

dcterms:publisher [ foaf:homepage <https://www.w3.org/> ] ;

This pattern is already used for people and their affiliation in this schema.
This could be enriched further, e.g.

Suggested change

dcterms:publisher <https://www.w3.org/> ;

dcterms:publisher [

a org:Organization;

foaf:homepage <https://www.w3.org/>;

foaf:name "World Wide Web Consortium (W3C)";

rdfs:seeAlso <https://www.wikidata.org/entity/Q37033>;

] ;

I have accepted the second option providing further erichment.

Ok, let's try to be future proof, no objection from my side.

@pchampin I have accepted your suggestions and updated the .jsonld and .rdf vocabulary serialisations.
If you can approve the PR, I would merge it, also considering that quite a large number of interventions have been piled into this PR, and keeping track of the changes is getting complex.
