Re: multilingual labels in SKOS

Strictly it would require non-standard code to validate, but you would
make up a temporary vocabulary which derived off of altLabel and
therefore be recognised by validators as part of the skos vocabulary.
Is there any need to denote prefLabel in each language within the one
concept?

It would be interesting if there were ways to add levels of
restriction for internationalisation to OWL natively. The only issue
currently is that the cardinality is restricted to a single statement
without regard for language... If you could have this cardinality
spread over the languages it would help.

For the immediate future you could quite easily just use altLabel with
a language tag to specify which language each altLabel is in. Do you
really need to restrict your system to only one in each language for
your system to work at all?
