To expand on this: In the linked data world, library systems are going to have to have was of keeping track of which assertions has come from which source, if only because the cycle-times of sources is incredibly disparate. There are several different approaches (named graphs, periodic rebuilding of a shared pool, etc), but the problem is faced by an incredibly broad class of linked data users, so by in large we can safely assume that suitable implementations will appear that we can use. cheers stuart
