Kurzfassung
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
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.
