Aren't categories a primitive form of index?

An idea. I'll try to be short.
Wikipedia has a lot of information, and it is heavily crosslinked. But it's not indexed. I mean an index of people, and index of places and an index of things. And events. And countries. And lakes. And whatever. Each index is a table (in database terms), with a few required fields. You could the add a page (or a part of it) to an index (or more indexes) by specifying theese required fields of an index (probably in the wiki source).
Using this you could look up things/people that happened, borned, died or whatever on a given day. Or things that happened in Tokyo. Or list books or movies that have wiki pages about them. Possibilities are quite broad. Look up pages that are in multiple indexes, "events" and "presidents of the world" for example.
