Enhancing Secured Service Interoperability with Decentralized Orchestration

Several current research efforts in business process modeling are investigating XML-based executable formal specification languages. The availability of the latter allows modeled processes to be exchanged between different organizations and executed without major architectural constraints. With the existence of services that are invokable with processes rather than their regular input, it is very inexpensive to provide decentralized execution settings where services can establish direct interconnections following the logic of their processes. This paper describes and exemplifies our initial ideas about a method that derives such processes. We are interested to satisfy different information flow policies of involved services and privacy requirements of process designers that run counter to default decentralizations. We show how decentralized executions can be effective for service oriented processes that cannot be realized with centralized executions.
