document: EDUTELLA : a P2P networking infrastructure based on RDF Metadata for the World Wide Web is important , but metadata for Peer-to-Peer ( P2P ) networks is absolutely crucial . In this paper we discuss the open source project Edutella which builds upon metadata standards defined for the WWW and aims to provide an RDF-based metadata infrastructure for P2P applications , building on the recently announced JXTA Framework . We describe the goals and main services this infrastructure will provide and the architecture to connect Edutella Peers based on exchange of RDF metadata . As the query service is one of the core services of Edutella , upon which other services are built , we specify in detail the Edutella Common Data Model ( ECDM ) as basis for the Edutella query exchange language ( RDF-QEL-i ) and format implementing distributed queries over the Edutella network . Finally , we shortly discuss registration and mediation services , and introduce the prototype and application scenario for our current Edutella aware peers .
