A Semantic Web Middleware for Virtual Data Integration on the Web
White Paper The proposed system allows retrieving data using SPARQL queries, data sources can register and abandon freely, and all RDF Schema or OWL vocabularies can be used to describe their data, as long as they are accessible on... [15 Jan 2009]
