nicholascar has just created a new issue for https://github.com/w3c/dxwg: == Formally align PROF to DCAT == Formally include DCAT alignment in the Profiles Vocabulary. The alignment would be made like this: `prof:Profile rdfs:subClass of dcat:Resource .` ### Changes * `prof:Profile rdfs:subClassof dcat:Resource .` * `prof:hasArtifact` replaced by `dcat:downloadURL` and `accessURL` * `prof:ProfileResource rdfs:subClassOf dcat:Distribution .` NB : prof:hasResource is not a sub-property of dcat:distribution because the domain of dcat:distribution is dcat:Dataset. Implementations may declare this is if required, to catalog profile descriptions using dcat:Dataset . prof:Profile and dcat:DataSet are not disjoint. #### Why now? * DCAT had not previously defined abstract dcat:Resource * It was not clear if something described in a document could be a dcat:Dataset * It was open for debate whether a dcat:Distribution was “informationally equivalent” to a Dataset ### Pros * Some PROF properties are able to be deprecated in favour of long-standing DCAT properties * Other previously proposed PROF classes and properties can be interpreted in the light of DCAT classes and properties which are widely understood * Use of DCAT indicates how to apply basic metadata properties to profiles since, if a prof:Profile is a dcat:Resource, then users would expect to see dtc:title etc. for it dcat:downloadURL and accessURL is more nuanced that hasArtifact * Resolves the debate about whether to force properties of distributions to be attached to the accessURL or allowed in the cataloged component (e.g. dct:format) ### Cons * PROF now has a dependency on DCAT (revised) which is a new (implication: somewhat un-tested) ontology * PROF has to both differentiate its classes and properties from other DCAT classes and properties while still being DCAT-compatible ### Implications: * Revisit if ProfileResource should be named more like Distribution (ProfileDistribution) Please view or discuss this issue at https://github.com/w3c/dxwg/issues/808 using your GitHub account
