Towards Executable UML Interactions based on fUML

Marc-Florian Wendland


Executable specifications for UML currently comprise fUML, precise semantics of composite structures and in future precise semantics for state machines. An executable semantics for UML Interactions is on the roadmap, but has not been addressed by the OMG Executable UML working group so far. Interactions are said to be the second most used diagrams after class diagram of UML, thanks to their comprehensibility and illustrative visualization. Unfortunately, they suffer from fuzzy semantics and technical issues that wastes the potential Interactions could have for engineering activities apart from high-level specifications. In this position paper we present first results from experiments and attempts to map UML Interactions to fUML Activities in order to eventually execute them.
