Abstract

Subject-oriented business process management (S-BPM) introduces a new technique for process modeling that emphasizes the importance of the actors in business processes (subjects) and gives a balanced consideration to subjects, their actions, and goals. Because of the formal foundation and the clear declaration of subjects, S-BPM allows the distributed modeling and execution of processes, without losing the capability to verify the compatibility of processes.

Executing cooperating processes in a distributed system also poses new requirements to the communication middleware, which is responsible for routing messages from one process instance to a remote peer process instance. In this paper, we describe an engine to execute S-BPM process choreographies. It is based on subject-oriented process modeling and a publish/subscribe middleware as communication basis. Our process engine also runs on mobile devices.
