Hi Bob,
yes, that's in theory. In practice, there will often be no direct  
interaction with the ontology labels, because the user interface is  
wrapped around the whole conceptual structures. Image the following  

- owners of car sales or rental sites add GoodRelations + VSO markup  
in RDFa to their page templates
--> they will have to use the ontology identifiers in the code. It may  
be that future Web authoring tools will help with RDFa patterns and  
offer the ontology element labels, but in all "raw" coding with Vi or  
whatever, developers will have to deal with the identifiers.

- applications will harvest and exploit the rich meta-data, filter /  
augment etc. them, and finally present them somehow to the user. But  
the applications won't use (and don't have to) display the labels  
attached to the elements in the ontology specification. They will use  
localized, context / application specific terminology.
--> users will not even spot the ontologies used by the app to present  
the results.

So I really think the multi-linguality of ontologies is overrated.  
Language tags are extremely powerful on the data level, though, for  
they simplify NLP processing / lifting.
