Hi Dan,


it shouldn't be a problem to export WordPress data.


If you want a database dump, as your script currently does, you have two options:

1. use D2RQ, write a map and execute a find(ANY, ANY, ANY) query, which will dump the whole database or

2.  use the old D2R tool, which is a command line tool for dumping relational databases as RDF. See http://www.wiwiss.fu-berlin.de/suhl/bizer/d2rmap/D2Rmap.htm for details.


Another interesting approach might be combining D2RQ with Joseki. The users could then query your WordPress database directly over the web using RDQL or FETCH and would only get the parts of the thesaurus that the are interested in, without having to download the whole thing.


If you need any help with writing the mapping or run in any other problems, just let me know.
