Side-note: triple pattern fragments always belong to a certain dataset, so there is always a closed-world assumption at work. But on the other hand, it is my opinion that the traditional SPARQL philosophy ignores the open-world assumption too much indeed. How meaningful are COUNT and NOT in an open world? How meaningful is a finite resultset? But that's a different story altogether :-) Suffices to say that triple pattern fragments make federated querying easier, or as Erik said, the client shouldn't care what server it is at, it just follows links. > I am convinced that other means to improve performance can be designed, > so that the server can provide the client with helpful information. True, but the 404 was a very easy win; none of the alternatives will be as light-weight (but we shouldn't do it if people don't think it's a good idea). Best, Ruben
