[Zope] request for data sets.

I'm looking for a largish data-set I can use for playing with in some query stuff I'm fiddling with. I know at one point PaulE said he had the IMDB database loaded into zope - I've not been able to find this on the web. Can anyone suggest a useful dataset? Preferably it would have: a number of different types of objects lots of cross-references between the objects various attributes for searching/sorting... ta, Anthony
