Did you Know that you can Download Wikipedia?

I have to confess, I didn't know it either. Wikipedia can be downloaded in a relational form and put directly in a database. In fact, to be more precise, you can choose to download only the parts that you require. Check out these links:

• The Wikipedia schema is at http://www.mediawiki.org/wiki/Manual:Database_layout 
• The files are at http://dumps.wikimedia.org/enwiki/latest/ and you can download each table individually.
• More instructions at http://en.wikipedia.org/wiki/Wikipedia:Database_download   

Go ahead and try it!
