So here's another query:

   select
     ?protein ?go
   using
     uniprot
   where
     { $protein [rdf:type] Protein } and
     { $protein classifiedAs $go }

Can you set a default namespace?

If you allow restrictions on namespaces, you could also add:

   and namespace($go) = 'urn:lsid:uniprot.org:go:'

Incidently, what's the overhead of federated queries? Let's say the GO data 
was stored in its own database (on the same server), how much would this 
slow down the query above?
