Abstract : With the development and adoption of web-based technologies, existing companies can establish new partnerships by composing existing services, thus offering new value-added services. However, the implementation of process interacting on the Web still remains a complex and tedious task. The concept of service, based on web technologies aims at acilitating the development of this type of process. Services that enter into compositions with other services may have transactional properties, especially those in the broad area of resource management (e.g. booking services). These transactional properties may be exploited in order to derive composite services which themselves exhibit certain transactional properties.
The work presented in this document led us to identify two main issues: (i) web service composition and (ii) transactional properties associated with this composition. As we are interested in both issues we have designed a framework called TCOWS - Transactional Composition Of Web Services - which covers the design of compositions of Web services as well as their executions. The framework relies on a model for the composition of Web services associated with transactional properties that takes into account the expression of the transactional properties that composite services are required to fulfil. In addition, compositions can be parameterised so as to allow the end user to impose that certain quality of services constraints and preferences are satisfied by the executions of the composite service. At execution time and relying on web service communities, TCOWS selects among services accessible through ommunities, those which best meet the composition's needs. The framework automatically ensures that transactional properties associated with the composition are fulfilled by exploiting the ransactional properties of the underlying selected services.
