Hi all,

Just to say I've added this to the proposals list as 'collections-5':

http://www.w3.org/2004/02/skos/core/proposals#collections-5

I've just described the problem with links to background material, I'll write up options for solution asap after second review is concluded.

Cheers,

Al.

I agree that concept and collection should be disjoint. In concept theory, a collection can be a descendent of a concept, and each item in the collection (which terminologists tend to think of as a set) is itself a concept, but the collection is just a way of containerizing these items that share a particular kind of relation to the initial concept.

and just below it I see a diagram wherein 

ex:milk skos:narrower [ rdf:type skos:Collection ].

and we have skos:narrower rdfs:subPropertyOf skos:semanticRelation,
so that

ex:milk skos:semanticRelation [ rdf:type skos:Collection ].

and 
and skos:semanticRelation rdfs:range skos:Concept
so that

ex:milk skos:semanticRelation
  [ rdf:type skos:Collection, skos:Concept ].

so the collection is a concept after all.

Please fix this inconsistency between the example and the prose one 
way or another.

I suggest keeping Collections and Concepts disjoint, and introducing
a narrowerCollection property.
