| Abstract | P2P applications for searching and exchanging information over the Web have become increasingly popular. This has lead to a number of (usually thematically) focused communities, which allow efficient searching within such communities, and which use specific metadata sets to specify the resources stored within the P2P network. By concentrating on domain and application specific formats for metadata and query languages, however, current P2P networks appear to be fragmenting into non-interoperable niche markets. This contribution describes 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 one basic service (query) and an Edutella application (annotation) within this network, both being built on a common query language exchange format, and specify the main architecture and APIs of the Edutella P2P network. 1. BACKGROUND While in the server/client-based environment of the World Wide Web metadata are useful and important, for Peer-to-Peer (P2P) environments metadata are absolutely crucial. Information Resources in P2P networks are no longer organized in hypertext like structures, which can be navigated, but are stored on numerous peers waiting to be queried for these resources if we know what we want to retrieve and which peer is able to provide that information. Querying peers requires metadata describing the resources managed by these peers, which is easy to provide for specialized cases, but non-trivial for general applications. In the context of educational resources for example, which we are currently focusing on, P2P-based approaches are more flexible than centralized approaches, with sev... |
