Abstract: Distributed Digital Libraries (DLs) integration is significant for the enforcement of novel searching mechanisms in the internet. The great heterogeneity of systems storing and providing digital content requires the introduction of interoperability aspects in order to resolve integration problems in a flexible and dynamic way. Our approach introduces an innovative service-oriented P2P system, which initialises a distributed ontology schema, semantically describing and indexing the digital content stored in distributed DLs. The proposed architecture enforces the distributed semantic index by defining virtual clusters consisting of nodes (peers) with similar or related content in order to provide efficient searching and recommendation mechanisms. Furthermore, a use-case example is presented in order to demonstrate the functionalities of the proposed architecture in a P2P network with DLs containing cultural material.
