Java FX? I work with a local MySQL database atm and the Google WindowBuilder toolkit is very useful to create rapid applications with Java. The intended use of my framework/algorithms is to extract and transform the data of Wiktionary and load it back into a new database (with an own scheme). So, this should run only once (!), after you downloaded the dump from the Mediawiki servers.

Then, one can write a tool, that e.g. generates a word net (which I am going to do); but you can do also other stuff (like using the inflection tables to generate a finite state machine that transform arbitrary german words from singular to plural or the like).

A colleague at our chair is researching semantic searches and things like GermaNet have to be licensed for commercial use; so a derived wordnet from the freely available Wiktionary project would be a great benefit for the Computational Linguistics Community.
