catalog.rdf.bz2 gets updated every night.

The individual rdf files don't get updated after first creation. That's 
something we will do eventually but need to figure out an efficient way.

Peacing the individual files together is not as easy as it seems because 
  we have to remove redundant information. We'll have to copy the entire 
database into a triple store and serialize it out again. Not likely to 
happen soon.
