Abstract
This paper discusses harmonization issues between the management of resources stored locally by users in personal repositories and the management of resources shared by a community which they belong to. The solution consists in maintaining the same kind of indexing. We discuss some requirements that the motivation implies and we present some choices that have been done for engineering the system that allows to manage different types of resources and that allows to describe them with ontological elements. This paper focuses on a knowledge-based representation of resources that supports the service that the community can bring to its members. We develop our approach of semantic indexing. Some constraints due to the nature of a distributed index are also presented. Peer to peer based communities rely on a decentralized system. The paper also presents the system engineering of a prototype that gives access to the resources. It explains how the architecture is structured and the role of its layers. The Web design of the front-end guarantees an anywhere and anytime access to the resources. The system supports an easy scalability thanks to its underlying architecture based on web services.
