Viewing the semantic web through RVL lenses

Abstract

Personalized access and content syndication involving diverse conceptual representations of information resources are two of the key challenges of Semantic Web (SW) applications. In this paper, we investigate how these goals can be achieved using view definition primitives over RDF/S bases. We introduce a full-fledged view definition language, RVL, for creating virtual RDF/S resource descriptions and schemas from (meta)classes, properties, and resource descriptions, and we illustrate how RVL views can be composed with structured RDF/S queries expressed in a query language like RQL, by means of an internal logical framework capturing the semantics of the RDF/S model, RQL queries and RVL views. © 2004 Elsevier B.V.
