playing par 2 with SPARQL and MASE, the search engine for lists.w3.org

Our MASE engine supports fielded search. I'm not sure whether it's done 
with SQL or not, but it probably can't do all of SPARQL 
straightforwardly, if only for denial-of-service reasons... but a smart 
SPARQL client should be able to negotiate with it... given a complex 
sparql query, send a simpler sparql query that MASE can handle, which 
would return a superset of the intended matches. Then the smart SPARQL 
client/proxy could re-run the original sparql query on the intermediate 
results to get the desired results.

The connection between ?subject=sparql style URI queries and SPARQL is 
a postponed DAWG issue. RDF forms and all that. The exact design hasn't 
come to me yet, but my intuition says that there's a useful mapping.
