Berners-Lee's vision of the Semantic Web describes the idea of providing machine readable and processable information using key technologies such as ontologies and automated reasoning in order to create intelligent agents. The prospective amount of machine readable information available in the future will be large. Thus, heterogeneity and scalability will be central issues, rendering exhaustive searches and central storage of data infeasible. This paper presents a scalable peer-to-peer based

The system relies on the graph-based W3C standard Resource Description Framework (RDF) for knowledge description. Thereby, it enables queries on large, distributed RDF graphs. 1
