A technical infrastructure for storing, querying and managing RDF data is a key element in the current semantic web development. Systems like Jena, Sesame or the ICS-FORTH RDF Suite are widely used for building semantic web applications. Currently, none of these systems support the integrated querying of distributed RDF repositories. We consider this a major shortcoming since the semantic web is distributed by nature. In this paper we present an architecture for querying distributed RDF
more &raquo; ... ries by extending the existing Sesame system. We discuss the implications of our architecture and propose an index structure as well as algorithms for query processing and optimisation in such a distributed context. Biographical notes: Heiner Stuckenschmidt is a Senior Researcher in the Knowledge Representation and Reasoning Group at the Vrije Universiteit, Amsterdam. His research interests include practical knowledge representation and non-standard reasoning for semantic search and information integration on the web; decentralised and context-based semantic systems and the use of semantic web technologies for the development of intelligent information systems for medical and scientific applications.

Richard Vdovjak holds a professional doctorate in software engineering and a PhD in computer science from Eindhoven University of Technology. Between 2004 and 2005 he was employed by the same university as assistant professor in the field of information systems and databases. From July 2005 he has worked for Philips Research Eindhoven. His research interests include ethodologies for engineering web information systems, information integration, architectures for distributed RDF(S) query processing, RDF(S) query optimisation, and model-driven software development. Jeen Broekstra is a PhD researcher in the Knowledge Representation and Reasoning Group of the Vrije Universiteit Amsterdam. His main research topic is storage, querying and inferencing for semantic web languages. He is also a software developer at Aduna and is one of the lead designers of the Sesame RDF Framework. He has (co)written numerous publications on semantic web technology.
