Wasn't there a use case about your bank statement being mashed with geographical data to show your itinerary. That would be on the very basic end of what I am taking about. I am taking about merging rich datasets to allow functionality making real use of densities of data to correct, infer, produce and to collaborate - and in rich interfaces that don't hint of a triple, but just leverage them. >> >> Where are these applications and what is required, on top of RDF, to create them.
