Abstract:In hybrid service composition approaches, processes are used to describe the core part of the composition logic whereas the rules are used to specify decision making constraints and conditions. These rules are exposed as services and are used in the processes whenever a certain decision has to be made. To evaluate these rules, we need a mechanism 1) to share data between the main process and the rule service; 2) to decide upon which service to invoke based on the result received from the rule service. In this paper, we propose a tuple space based solution for supporting these requirements. We also include descriptions of an application scenario to motivate our work, a prototype of the proposed solution and we demonstrate how our solution helps in achieving process flexibility with minimal maintenance costs in the context of changing requirements.
