Dear LOD community,I'm wondering whether there has been any research regarding the idea of having URIs contain an actual URI, that would then resolve information about what the linked dataset states about the input URI. Example: http://foo.com/alice -> returns data about what foo.com has regarding alice http://bar.com/endpoint?uri=http%3A%2F%2Ffoo.com%2Falice -> doesn't just resolve the alice URI above, but returns what bar.com wants to say about the alice URI For that matter http://bar.com/?uri=http%3A%2F%2Ffoo.com%2Falice could return: <http://bar.com/?uri=http%3A%2F%2Ffoo.com%2Falice> a void:Dataset . <http://foo.com/alice> <#some> <#data> . I know SPARQL endpoints already have this functionality, but was wondering whether any formal research was done towards this direction rather than a full-blown SPARQL endpoint. The reason I'm looking for this sort of thing is because I simply need to ask certain third-party datasets whether they have data about a URI (inbound links). Best, Luca
Luca,I don't totally understand your quest, but I have a hunch you might be looking for something like:
