Abstract

Due to the information growth, distributed environments are offered as a feasible and scalable solution. Peer-to-Peer (P2P) networks have become one of the most important and used distributed environments inside (and outside) the e-learning community. They bring many advantages such as high flexibility for peers to dynamically join or leave the network, scalability, autonomy and high resilience against peer failures. However, every single one of them typically uses an interface specifically developed for that network, and it requires every peer to implement it in order to join. This is leading to increased development costs for potentially new participants of the network, and usually makes different P2P networks unable to interact with other systems and environments, isolating the network as a whole. In this paper, we report on a solution based on a proxy-based architecture and semantic mappings in order to allow the sharing of content between the set of peers inside a P2P network and other systems outside the network. Furthermore, we present an open-source implementation of the modules described in the paper.
