Abstract

The open source project Edutella is an RDF-based Peer-to-Peer infrastructure for digital resources, focusing on learning materials. Building upon the established meta-data standard RDF(S) appropriate for the description of distributed resources in theWorld Wide Web WWW, it provides a general RDF-based meta-data infrastructure for P2P applications. In this paper, after a short introduction to the Edutella infrastructure, we describe how an Edutella peer based on the conceptual modeling language O-Telos, using the ConceptBase meta-database, can provide storage and reasoning capabilities on RDF meta-data in the P2P network. To provide this feature, we exploit the similarity of the O-Telos data model to the RDF(S) data model, and showhowRDF(S) meta-data can easily be stored in the ConceptBase database. Finally, we describe how the Datalog-based Edutella query exchange language RDF-QEL can be naturally expressed by O-Telos query classes.

On leave from University of Hannover We will use the expression RDF(S) throughout this paper to refer to RDF schemas and RDF data.
