Hi Henry, I dont see how sparql exactly saves them bandwidth.. I havent been much into sparql lately but last i checked it was supporting the named graph paradigm which means you'd ask amazon for their entire graph and then execute the query locally. If you meant that amazon would instead execute an sparql query for you an return you just the very hits then a) if just some sparql queries are allowed, isnt this what a web service would do today anyway with just rdf results? b) otherwise, would they really allow you to execute arbitrary graph queries? complexities usually explodes exponentially (possibly) with the number of unbounded variables, and is very sensitive to the data structure as well c) even if they really did execute our arbitrary query, would they provide the answer we look for? if you want to know all amazon books written by a stanford professor there is no way out. There must be a computational space where the list of professors and the list of books is known at the same time. What to do then, cause amazon to request the list of professors from stanford and execute the query there? Giovanni
