RE: Use AND type references

Bernard,

Hmmm...  since "cut flower production" is a concept, but actually
expressed by two preferred terms, I am glad to see that your new idea is
to have it as a subclass of Concept.  That is logical to me.

Simple is good and it makes sense.

Thanks for your reply!  
Good to hear from Stella too!

Lori

Second thoughts ...

Thinking about it, skos:prefLabel is *not* mandatory for skos:Concept.

So maybe we do not even need a particular class for the AND concepts
but simply use blank skos:Concept nodes.

<skos:Concept rdf:ID="foo">
	<skos:AND rdf:parseType="Collection">
		<skos:Concept rdf:about="http://thes.org#cut_flowers"/>
		<skos:Concept
rdf:about="http://thes.org#crop_production"/>
	</skos:AND>
	<skos:altLabel>cut flower production</skos:altLabel>
</skos:Concept>

Maybe too simple to be true :)
