ABSTRACT
Today, enactment of Web service flows -- the process of evaluating control flow and executing activities a workflow is composed of -- is typically done by a centralized workflow enactment service as part of a Workflow management system. This exhibits a number of drawbacks with regard to process adaptability and process fragmentation among a number of participating partners. In order to overcome the deficiencies of centralized process navigation, we propose a model for flexible and adaptable distributed processes as orchestrations of a set of self-coordinating components, without the need for central coordination. Furthermore, we provide key characteristics and an architecture for the development of a supporting infrastructure that facilitates both, deployment and management of distributed components as well as decentralized workflow enactment.
