Grazie Andrea,
     but what if I need to access data from a SPARQL endpoint? Could I 
use Joseki to query two different models (one inferred, and one 
"simple") such that they are based on the same data? Please note that 
I'd like to have the possibility to execute updates too.

Cheers,
     Riccardo
