Thank you, very good job. But really i can't understand how I could make 
a query that involves information in my knowledge base and from another 
one. For example, suppose that I stored in my KB all the festivals in 
Italy, recording also the city (simply an uri) where this event holds.  
How I can  get  all the festival in Sicily? For instance, is should get  
all the cities of sicily  from your  (remote)  KB and  get all the  
fests in these ones  from my KB.
