GSS: A generic P2P semantic service oriented architecture

Due to their two main applications, instant messaging and file sharing, peer-to-peer (P2P) systems are gaining more and more attention. JXTA, an interoperable and platform independent peer-to-peer computing infrastructure, has been adopted in an increasing number of network applications providing cooperative services and more specifically a file-sharing service through the CMS layer (content manager service). In this paper, we propose a generic P2P semantic service oriented architecture (GSS) which encapsulates and enhances the JXTA-CMS architecture, by offering a generic support for services of any kind, as well as by adding a semantic layer at the resource description level. In order to manage and secure the use of services, GSS relies on the integration of reputation-based and semantic policy-based trust management. An application called ldquoshare ITrdquo has been implemented to validate the GSS architecture.
