There are triples stores that do reasoning, and what they contain are 
datasets. Unfortunately, in this debate, I've not heard from the folks 
who implement them.
I'd like to see what, e.g., OWLIM, Virtuoso are doing with named graphs 
when you switch on inferences, but looking at the documentation, I don't 
find a clear answer.
