Sure enough. But at least we could help proposing at least one. :-)

Yes, this is a good use case for mapping, either SKOS-to-SKOS mapping, 
or mapping from some RDF dialect to another. You know it's one of my 
favourite topics.

I've been searching the W3C I18n Activity 
http://www.w3.org/International/ which looks to me the place where such 
things should happen, but it looks like at first sight there is no 
connection between this activity and the SW activity. I will investigate 
further.

Indeed. By the way, Happy Xmas to all :-)
