The increasing popularity of Web services for application integration has strengthened the need for automated Web services composition. In order for this to succeed, however, the joint execution of Web services requires a coordination model. Coordination's main use is to solve conflicts between Web services. Conflicts could be on sharable resources, order dependencies, or communication delays. The proposed coordination model tackles these conflicts with three inter-connected blocks defined as conflict, exception, and management. Conflicts among Web services raise exceptions that are handled using appropriate mechanisms as part of the coordination model. The deployment of this model is illustrated using a simple yet realistic example.
