SEA: A Lightweight and Extensible Semantic Exchange Architecture

With novel centralized information management systems, users benefit from collective data organization. Centralization, however, also imposes privacy and availability constraints. With this work we present SEA, a semantic exchange architecture for distributed information management that employs Peer-to-Peer networking, social information management, and semantic web technologies. SEA addresses privacy and availability by storing data locally while utilizing it globally. The benefits of collective information tagging as oered by prominent centralized services are available through anonymous tag distribution in the Peer-to-Peer network. More fine grained access control allows to share data both publicly with all connected peers and privately within networks of trust. In this paper, we present the initial architecture and early implementation details of the prototype.
