....is indeed a great danger (as already discussed in [8] that unifying interfaces and protocols introduced by the World Wide Web get lost in the forthcoming P2P arena. The Edutella project [9] addresses these shortcomings of current P2P applications by building on the W3C metadata standard RDF [22, 2]. The project is a multi staged effort to scope, specify, architect and implement an RDF based metadata infrastructure for P2P networks based on the recently announced JXTA framework [10] The initial Edutella services will be Query Service (standardized query and retrieval of RDF metadata) ....
....rules, but can use the predefined semantics for these edu:properties directly. 6 This keeps the clear semantics for RDF QEL i, but allow abbreviations which make it easier to write Edutella peer wrappers. 4. 7 Querying Schema Information As apparent already from the RDFS schema definition [2], and discussed in more detail in the recent RDF model theory [12] see also the axiomatic definition of an extension of RDFS we called O Telos RDF [29] RDFS does not distinguish between data and schema level, and represents all information in a uniform way as a graph. Indeed, as discussed in ....

....complex and varying metadata sets, and avoid creating another special purpose application suitable only for a specific application area which is outdated as soon as metadata requirements and definitions change. The Edutella infrastructure [4] therefore builds on the W3C metadata standard RDF(S) [1], and uses a standard query model suitable for this formalism, based on Datalog, to exchange queries throughout the Edutella network. For the local user, the Edutella network transparently provides access to distributed information resources, and different clients peers can be used to access, ....

.... will only be successful with more complex metadata (such as those described above) and also needs more advanced query capabilities. The Edutella project [22, 23] http: edutella.jxta.org) addresses these shortcomings of current P2P applications by building on the W3C metadata standard RDF [20, 6], and is based on the assumption that all resources managed within the network are described by RDF metadata. The Edutella Query Service is a standardized query exchange mechanism for RDF metadata stored in distributed RDF repositories and using arbitrary RDFS schemata. Edutella peers can be ....

The core categories for learner data in IMS LIP [6] 4 Semantic web technologies Semantic web technologies like the Resource Description Format (RDF) 8] or RDF schema (RDFS) [1] provide us with interesting possibilities. RDF models are used to describe learning resources. The RDF bindings of Learning Object Metadata (LOM) 10] can be used for these purposes. The RDF model can be used for learner description as well. RDF schemas serve to define vocabularies for medatada ....
