Working with Wikipedia data
The good people at Freebase launched WEX, a Wikipedia Extraction tool, and made their exported data downloadable.
This allows you to use our usual text, XML or even SQL processing tools to analyze Wikipedia entries.
I mention this because the FreeBase project is one of the most interesting thing happening in the online knowledge space. If you haven't noticed, this project is building a huge structure data repository, open and extremely linked, with strong meta-data.
You should check it out.
