Hi all,

In the process of creation in SKOS of the territorial thesaurus of Spain 
and France, we have fount two problems about how to represent some 
characteristics related with the preflabel property.

First:

The comments of the preflabel property says: "/No two concepts in the 
same concept scheme may have the same value for skos:prefLabel in a 
given language."/

But for a territorial thesaurus there are different places with the same 
name (for example, two cities with the same name in different provinces)
I think this is not a problem if the two concept have different 
identifiers, that depends of the kind of thesausus that is being 
created, in some of them  the repetition of preflabels is not 
recomendable but in others should be posible.

Second:

In the territorial units thesausus, we have a label that is the "oficial 
name" of a place, that can be in different languages for different 
cities in the same country. For some of hte places there is translation 
of that label to the other official languages of the conuntry but for 
others there is not translation and the "oficial name".
We consider that label the default label to return when there is not 
translation in the language we are aking for, but we dont have clear how 
to represent that label.

Our alternative is to put the "oficial name" as a preflabel without 
language (considering it a kind of default preflabel) and the 
translations as preflabels with language property, but we are not sure 
if this aproach is valid in SKOS.

Example:
<skos:prefLabel>ILLES BALEARS</skos:prefLabel>  (Oficial name)
<skos:prefLabel xml:lang="es">ISLAS BALEARES</skos:prefLabel> (Translations)

Thanks in advance,
Javier
