It's an nquads file with 4,9 mio named graphs - data we crawled from the web
for foaf-search.net with the file url as graph. Many foaf profiles with blank 
nodes but also other data that uses foaf:name. There are also other nquad 
files with DBpedia quads but these should be processed much later.

I don't know. I can check with a SPARQL query on an older TDB version
of the data if you want.
