BTW: The note on http://wiki.foaf-project.org/w/DataSources that the Billion
Triples Challenge 2009 contains "40 million FOAFs" is a bit misleading. If you
follow the link you can see that there are 39 mio "X a foaf:Person" assertions 
in the dataset which boils down to much less distinct foaf:Persons. We have
ca. 40 mio "X a foaf:Person" assertions and ca. 3.5 mio distinct foaf:Persons.
