Sharing the semantic web data encoded in Resource Description Framework (RDF) triples from proprietary datasets scattered around the Internet, calls for efficient support from distributed computing technologies. The highly dynamic ad-hoc settings that would be pervasive for semantic web data sharing among personal users in the future, however, pose even more demanding challenges for the enabling technologies. The authors extend previous work on a hybrid Peer-To-Peer (P2P) architecture for an ad-hoc semantic web data sharing system which better models the data sharing scenario by allowing data to be maintained by its own providers and exhibits satisfactory scalability owing to the adoption of a two-level distributed index and hashing techniques.
