Kurzfassung:

Service composition is a recent field that has seen a flurry of different approaches proposed towards the goal of flexible distributed heterogeneous interoperation of software systems, usually based on the expectation that such systems must be derived from higher level models rather than be coded at low level.

We propose a conceptual modelling approach for the composition of service processes into a task workflow and its dynamic adaption to changes during runtime. The contribution of the paper is twofold. Firstly, our approach improves on existing approaches by the separation of configuration into service configuration and service instance configuration which reduces the reconfiguration cycles in case of changes and secondly, we describe a comprehensive modelling concept that combines existing dynamic composition techniques in a novel way.
