Looking for XML and dictionaries I found a free dictionary with said amount of words. It is based on the "Webster's Revised Unabridged Dictionary Version published 1913" and on WordNet, a semantic network created by the Cognitive Science Department of Princeton University" ..This electronic dictionary is published under the GPL. It is using "GCIDE_XML".

There are also standards for this kind of content; ISO 12620, a JAVA application from IBM "Dictionary and Thesaurus API for Java", an article how the OED Oxford English Dictionary uses SGML for its electronic content [http://www.ariadne.ac.uk/issue24/oed-tech/]

I am still only scratching the surface...

http://www.w3.org/2001/sw/Europe/reports/thes/ Semantic web..

The list goes on. What I am now looking for is an aricle that explains in simple terms what the relations between all these systems are and what they are good for.

Thanks, Gerard
