Yes we tried that.

I think some Virtuoso deployments will only want to expose the data available locally. For example, when using Virtuoso as a datawarehouse solution with Closed World behaviour. For now the hack will do, but if you have any update on this, let us know. Our solution for now looks something like this: 1) http://data.domain.com/something -- 303 --> http://data.domain.com/page/something 2) http://data.domain.com/page/something --(internal)--> /description.vsp?uri={uri}$local=true the local=true flag does the following: * Turn off sponging * Make SPARQL queries just hit the local ( NULL ) graph * Avoid creating proxy URIs for links ( just expose verbatim URIs as hrefs ).
