Kurzfassung
RDF-based P2P networks have a number of advantages compared to simpler
P2P networks such as Napster, Gnutella or to approaches based on
distributed indices on binary keys such as CAN and CHORD. RDF-based
P2P networks allow complex and extendable descriptions of resources
instead of fixed and limited ones, and they provide complex query
facilities against these metadata instead of simple keyword-based
searches.
In this paper we will discuss RDF-based P2P networks like Edutella as
a specific example of a new type of P2P networks - schema-based P2P
networks - and describe the use of super-peer based topologies for
these networks. Super-peer based networks can provide better
scalability than broadcast based networks, and provide support for
inhomogeneous schema-based networks, with different metadata schemas
and ontologies (crucial for the Semantic Web). Based on (dynamic)
metadata routing indices, stated in RDF, the super-peer network
supports sophisticated routing and distribution strategies, as well as
preparing the ground for advanced mediation and clustering
functionalities.
