This will be a very cool feature. Ideally, I should be able to totally abstract myself from where the SPARQL code I am writing is being run. Probably defined a priori by using a new "remote" keyword, etc. for ( remote <http://ex.com/sparql> select * where { ?s ?p ?o } ) do { ... } def remoteEndpoint varchar ; remoteEndpoint := 'http://ex.com/sparql'; for ( remote ?:remoteEndpoint select * where { ?s ?p ?o } ) do { ... } def remoteEndpoint varchar ; remoteEndpoint := null; -- this is analog to not using the remote keyword, will evaluate locally for ( remote ?:remoteEndpoint select * where { ?s ?p ?o } ) do { ... } Regards, A > > Best Regards, > > Ivan Mikhailov > OpenLink Software > http://virtuoso.openlinksw.com > > > On Mon, 2009-10-05 at 00:15 -0400, Aldo Bucchi wrote: >> Hi, >> >> I find myself in a situation where I want to issue SPARQL queries to a >> certain endpoint ( linkeddata.uriburner.com/sparql ), but I want to >> use procedures, inference rules, and other magic to avoid bloating my >> client side code. >> Unfrortunately I cannot install these procedures in the target >> instance ( I don't control it ). >> >> I wonder ( and I imagine this touches on forthcoming federation ) if I >> could create such procedures in an instance that I control, but then >> make sure that the SPARQL queries within are federated to the target >> endpoint. >> Comments?
