Hybrid Service Modeling in Enterprise Computing

The Internet evolved to a generic platform and became fully pervasive infrastructure providing services anywhere and anytime. Hence the assumption is that any service requested by any business process is already provided somewhere in the Internet. This requires that services are conceptualized to fit descriptions of business process but on the same time rely on their technical specification, hence the semantic distance between business processes and service technology must be bridged. "Service modeling" has been identified as a promising concept to enable such semantic bridging. Each phase of Service Life Cycles is well supported by a range of service models. The research challenge of this paper is to introduce a holistic modeling framework that enables the use of hybrid service models to bridge larger semantic distances than by using only individual service models. The paper discusses the motivation, challenges as well as the conceptual and technical approach before introducing prototypes as a proof of concept.
