Description
Summary:In Service-Oriented Architectures (SOA) services are composed by coordinating their communications into a flow of interactions. Coloured Petri nets (CPN) offer a formal yet easy tool for modelling abstract SOAs. Still, mapping abstract SOAs into executable ones requires a non-trivial and time-costly analysis. Here, we propose a methodology that maps CPN-modelled SOAs into executable Jolie SOAs (our target language). To this end, we employ a collection of recurring control-flow patterns, called Workflow Patterns, as composable blocks of the translation. Following our methodology, we discuss how the Workflow Patterns we consider are translated in Jolie. Finally, we validate our methodology with a realistic use case. As additional result of our research, we could pragmatically assess the expressiveness of Jolie with relation to the considered Workflow Patterns.
