A Transactional Framework for Reliable Web Services Compositions to support Inter Enterprises Cooperations

Colloque avec actes et comité de lecture. internationale.International audienceThe evolution of Internet, as a communication support between applications and organizations, is reshaping inter enterprizes cooperations. Cooperating organizations can externalize their business processes as Web services and make them accessible. Then, they can cooperate by composing this externalized Web Services to form an inter enterprizes cooperative process. However, multi partners aspect, peer to peer architecture and collaborative nature leads to face and solve many problems. First, we have to deal with heterogeneity of internal processes transaction models. Second, we should be able to model complex interactions of the cooperation in a peer to peer and loosely coupled context. Finally, composed Web Service must be consistent. Unfortunately current Web services and business processes technologies do not provide efficient solutions for correct compositions and reliable executions of Web services compositions. In this paper we present an abstract of our doctoral work and its current state. We present a transactional framework which allows to define, model and carry out inter enterprizes cooperations byWeb services composition in a correct and reliable manner
