RE: [SKOS] Reference abstract and synopsis

Hi Antoine,

Thanks a lot for these comments, really helpful. A couple of remarks...

Do you mean that you think the SKOS Reference should say things like, "do not assert x y z..."?

If that is what you mean, then I don't think you can prevent anyone from asserting triples. 

All I think you can do is put semantic conditions in the normative specification which would make certain statements inconsistent with the normative semantics.

E.g. if you *don't* want people to say

skos:Concept rdfs:subClassOf owl:Class.

then you have to put something in the normative semantics which would make the statement inconsistent, e.g. 

skos:Concept owl:disjointWith owl:Class.

I think you have to accept that people can make any statement whatsoever which is consistent with the normative semantics, and still "conform" to the standard.

The term "paradigmatic" comes from the BS 8723 standard. "Paradigmatic" relations, which are inherent in the meaning of concepts, are distinguished from "syntagmatic" relations, which occur when two concepts are both subjects of the same document (if I've remembered correctly :).

If "paradigmatic" is not helpful to the wider community then I'm happy to drop it.

Cheers,

Al.
