Just some ideas - do not know what Alistair has in store about it.

1. You do not want to create an explicit descriptor for "cut flowers" AND "crop
production".
2. But you want anyway to hang the alternative label "cut flower production" to some
resource.
3. Actually ("cut flowers" AND "crop production") is a concept

What comes to mind is to use "blank concept", defined by some "AND" operator defined in
the SKOS namespace.
Something like

<skos:AND-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:AND-Concept>

Note that skos:AND-Concept is not a subclass of skos:Concept, since it does not bear
prefLabel

How does that fly?

Objet : Use AND type references


Pardon if this was already discussed -

I don't see an accommodation of USE "AND-TYPE" cross references in the SKOS core nor in
the SKOS Extensions.

An example of AND-type cross reference in thesauri:

cut flower production USE cut flowers
                               AND crop production

This indicates to the indexer and searcher to use both preferred terms, "cut flower" AND
"crop production" for indexing and retrieval of the concept "cut flower production".

For NISO Z39.19 thesaurus standard, this is section 8.2.5. "Cross-references to Elements
of Compound Terms"

Any previous discussion or suggestions for how these can be handled in SKOS?

Thanks,
Lori
