Why not relax range constraint for dcat:theme? In the biomedical domain we have more ontologies and often these ontologies have owl:Class typing for concepts.

There was also a discussion around the range for dcat:theme at: #1153

I would be comfortable relaxing the ranges of theme and themeTaxonomy. But it is important to keep them as object-properties, since the object must be denoted by a URI - i.e. taken from a managed source somewhere.

All, there was an earlier discussion on this (see here), where I noted that dcat:theme was explicitly minted for DCAT version 1 because it was felt that the range of dct:subject was too broad and that it would be useful to have a property with a range restricted to skos:Concept. Otherwise, dct:subject could have been used.
Now, with the relaxation of the range of dct:subject, which now also allows for textual values, I guess that dcat:theme with relaxed range, but still requiring it to be an object property, can still be seen as a restriction on dct:subject, effectively making it the same as the 'old' (pre-relaxation) dct:subject. Right?

@dr-shorthair yes, it could work for our use cases if dcat:theme is an object property

@makxdekkers I see your point. As I mentioned early in biomedical domain we have more owl based ontologies and vocabularies. So if you still like to restrict range of dcat:theme property it would be nice to have list of values like skos:Concept, owl:Class.
