Deriving business service interfaces in Windows Workflow from UMM transactions - long version -

Modeling inter-organizational business processes identifies the services each business partner has to provide and to consume as well as the flow of interactions between them. A model-driven approach to inter-organizational business processes allows abstracting from the underlying IT platform and, thereby, guarantees to survive changes in technology. UN/CEFACT's Modeling Methodology (UMM), which is defined as a UML profile, is currently one of the most promising approaches for modeling platform-independent business collaborations. However, well defined mappings to most of the current state-of-the-art candidate platforms are still missing. A candidate platform of growing interest is the Windows Workflow Foundation (WF). In this paper, we outline a mapping from the basic UMM building blocks, i.e. business transactions, to business service interfaces (BSI) implemented in WF. Our approach shows that UMM business transaction models greatly abstract from the complexity of a BSI.
