[Pellet-users] how to retrieve all instances in pellet(using sparql!!)

[Evren Sirin]

I don't think I understand the use case but the simple SPARQL query 
"SELECT * WHERE {?s ?p ?o}" can be used to retrieve all inferences. 
However such a query will typically run quite slowly since retriveing 
all the inferences is a quite expensive operation. Running specific 
queries that are relevant for your use case would be better.

Cheers,
Evren
