Re: Dereferencing a URI vs querying a SPARQL endpoint

Hi, If you have a dataset that is very large and highly interlinked on particular URI's, the DESCRIBE response may be too large to reasonably transmit to a user over the internet (and to expect a sparql endpoint to give out in one chunk). This is assuming the typical DESCRIBE behaviour that sparql

Dan and Hugh, let me be more specific. I'm not really advocating that only *one* direction should be returned (or even both directions). I am asking a more general question (to which I don't think Hugh really gave an answer either) which is, is there any query that returns the same triples as t
