Hi Bradley,

The EUROVOC model [ev] maps its model as follows into SKOS-XL [xl] (using
examples from previous responses):
<C1> a skos:Concept;
     xl:prefLabel <L1>.
<L1> a xl:Label;
     xl:literalForm "bass (fish)"@en;
     ev:qualifier "fish"^^xsd:string .
<C2> a skos:Concept;
     xl:prefLabel <L2>.
<L2> a xl:Label;
     xl:literalForm "bass (music)"@en;
     ev:qualifier "music"^^xsd:string .
Using skos rules, this also generates:
<C1> skos:prefLabel "bass (fish)"@en .
<C2> skos:prefLabel "bass (music)"@en .

This captures standard guidelines as follows:
- in EUROVOC, the skos:prefLabel are unique per language
- The qualifier is used as prescribed by the standard
There is no property for the qualifier in skos, hence the definition of
ev:qualifier.
The property is only useful for applications that need the label as such
without its qualifiers.
(e.g. qualifier management, ...).
