Decentralized Execution of P2P Collaborative Processes

The growing importance of exchanges and collaborations in all business areas calls for fast, efficient, and flexible models of computersupported cooperation. As the traditionnal client-server paradigm is hampered by its structural limitations, the interest of the Information System Community is aroused by the promises of alternatives known as peerto- peer approaches. This paper introduces a generic architecture, P2P Coop, designed for the execution of collaborative business processes. Basic motivations of the model are discussed, as well as major contributions notably in terms of service-oriented routing and failure handling.
