Requirements for Implementing Business Process Models through Composition of Semantic Web Services

Abstract

Despite significant research efforts, automated service composition is neither taken up broadly nor can it be considered a solved problem. We believe that this is partly the case due to an unclear formulation of the actual business requirements and frame for this technology. In this paper, we formulate a list of 14 requirements for composition in the contexts of business process implementation, enterprise application integration, and interoperability, which can be considered quite challenging not only for current technology but also in terms computational complexity. However, if these requirements are met by an approach to composition - potentially by combining existing technology - the relevance of automated composition to enterprise application software could increase significantly, and also quicken its success in other usage scenarios. We give a list of requirements towards service composition along with a starting point for a composition approach and a short analysis of the computational complexity.
