Hi,
Not sure if the question is for me or everyone else... Anyway, as hinted, here's my vote: I can live with EnumConcept, though I prefer "concept" or "category".

But if some here prefers to use the schema.org <http://schema.org> namespace, we can't really say it's wrong. Especially when better-known ontologies have been already integrated into Schema.org. The discussion should have happened for FOAF and GR. And if it happens now, still, it should have a broader scope than SKOS!

A range of simple applications like the one Stéphanes has presented don't need fully-fleged ontologies, or, here, fine-grained instances of schema.org <http://schema.org>'s 'concrete' classes.

>     SKOS was partly designed to reflect the shift to 'traditional' term-based knowledge organization systems to more 'conceptual' ones (a shift examplified by more recent thesaurus standard). As Jean-Pierre said, the whole point is having string and terms masquerading as something more structured. Having skos:Concept mapped to a schema:Term or anything that prominently feature 'term' will be harmful in this respect.
