Towards a semantics of activity diagrams with semantic variation points
Hans Grönniger, Dirk Reiß, Bernhard Rumpe⋆ · 2010
Abstract. UML activity diagrams have become an established notation to model control and data flow on various levels of abstraction, ranging from fine-grained descriptions of algorithms to high-level workflow models in business applications. A formal semantics has to capture the flexibility of the interpretation of activity diagrams in real systems, which makes it inappropriate to define a fixed formal semantics. In this paper, we define a semantics with semantic variation points that allow for a customizable, application-specific interpretation of activity diagrams. We examine concrete variants of the activity diagram semantics which may also entail variants of the syntax reflecting the intended use at hand. 1
