Is there a way to run SPARQL queries in RDF generated for a particular type of node? For example, if I have a type of content called people described in the FOAF ontology, can I run SPARQL queries on nodes like People?
If you try to execute a query from one site to another (see my comment), you can achieve this using the SPARQL Views module . This recent article provides an excellent reference to using SPARQL with views.
