1. - a collection 
of SPARQL queries (3 part series from basic to advanced with extensions)
2. - short cut to some of the advanced 
and extension queries showcased at last year Billion Triples Challenge.

Endpoint:  (over 4.5 Billion Triples at 
your disposal and counting).
Note, whenever you get an incomplete result set by way of error (e.g. 
some of the Billion Triples queries, simply re-query as this is the 
Anytime Query Feature in action).
