Change Details

We should provide a set of test data for people to play with. This should include: * An XML dump of all properties from wikidata.org * An XML dump of items about chemical elements (plus a few associated items) * An XML dump of wikidata's sites table These should come with instructions about how to import these, and some configuration snippets needed for setting up the wiki in a way that is compatible with the dumps (items in the main namespace, etc)
