Hi Brad, actually is there a schema of the graph? you said "directed", hence there should some hierarchy in it too.' I read there are 50K+ categories, maybe is there any list of "directions" aka "links" of how categories are connected?

Hi, Whats the simplest way to extract complete and the latest Wikipedia

Hierarchy?
Note that the "category hierarchy" isn't much of a hierarchy; it's a directed graph with cycles and no particular root.
Your best bet is probably to download a database dump from http://dumps.wikimedia.org/enwiki/latest/ and process it.
