Overheard: Creating the semantic graph with RDF and OWL

It understands how to use App B’s data set, and how to correctly make new links using that data set which are consistent with the meaning of the links it contains.

Nova Spivack, Defining the Semantic Graph — What is it Really?

This is the real point of the Semantic Web open standards — RDF enables data to be represented in a database independent manner, and OWL enables the semantic of that data to be defined in an open machine-understandable way so that other applications can use that data without having to first be programmed to do so. As long as they speak RDF/OWL, applications can use any data they find and lookup the meaning of any data they need to use so they can use the data appropriately.
