Abstract : The Semantic Web enables the possibility to model, create and query resources found on the Web. Enabling the full potential of its technologies at the Internet level requires infrastructures that can cope with scalability challenges while supporting expressive queries. The attractive features of the Peer-to-Peer (P2P) communication model, and more specifically structured P2P systems, such as decentralization, scalability, fault-tolerance seems to be a natural solution to deal with these challenges. Consequently, the combination of the Semantic Web and the P2P model can be a highly innovative attempt to harness the strengths of both technologies and come up with a scalable infrastructure for RDF data storage and retrieval. In this respect, this survey details the research works adopting this combination and gives an insight on how to deal with the RDF data at the indexing and querying levels. We also present some works which adopt the publish/subscribe paradigm for processing RDF data in order to offer long standing queries.
