Hi Ricardo,

> Is  this correct, or the GROUP BY is an extension?

Aggregates are not part of SPARQL as currently released, so you can't  
do GROUP BY. Neither can you do COUNT(?matricula).

Your implementation might support these, but most don't.

You also need to drop the angle brackets around your abbreviated  
resources — <ex:Pessoa> should be ex:Pessoa.
