In this paper, we present a scalable Peer-to-Peer RDF repository, named RDF-Peers, which stores each triple in a multi-attribute addressable network by applying globally known hash functions. Queries can be efficiently routed to the nodes that store matching triples. RDFPeers also supports users to selectively subscribe to RDF content. In RDFPeers, both the neighbors per node and the routing hops for triple insertion, most query resolution and triple subscription are logarithmic to the network

RDFPeers Architecture Our distributed RDF repository consists of many individual nodes called RDF-Peers that self-organize into a multi-attribute addressable network (MAAN) [8] . MAAN extends Chord [41] to efficiently answer multi-attribute and range
