Sounds very interesting.

We use RDF with environmental terminology in www.gein.de in Germany. Last
week we had a workshop, starting the development of an "Environmental Markup
Language" which will be RDF + eml-namespace + vocabulary. There is a
12-lingual environmental thesaurus named GEMET, maintained by the European
Environmental Agency. We want to convert this thesaurus into the form of a
topic map (see http://www.topic-maps.com/lit/iso13250/iso13250-1999-fcd.htm
or www.topic-maps.de). I think topic maps are a good structure for
vocabularies in the semantic web.
