I consider this partially an issue in content interoperability, when the
ontologies are actually in different natural languages (can be very
related to machine translation via interlingua). 

On the other hand, if it's immaterial in which natural language the
ontology concepts are represented, you still need to be able to express
the terms naming or associated with those concepts in alternative
natural languages. B2B e-commerce has this problem, i.e., you need to
provide localization and internationalization support, which will also
include cultural issues (but that is a more tangential issue for us).
So, the Web Ontology Language will need to have so-called "display
names" which will be partially language dependent and partially
application/use/task/device dependent. Synonyms (and their contexts of
use) may need to be supported (this gets into the notion of
"presentation", view too).

I'll look at your url.
