Using Executable UML to model algorithmic aspects of visualization systems

The XML based modeling language of graphical user interfaces for visualization systems in automation, XVCML, has been developed to ensure the consistency of visualization solutions in the fast-moving field of consumer technology. Until now, it only provides modeling elements for visualization of real time process data and the necessary communication relationships with data servers. In order to be accepted in practice, XVCML also needs modeling components for additional, user defined algorithms. This paper presents an approach to enhance XVCML with generic, algorithmic components to perform e.g. simple algebraic operations. For this purpose, Executable UML has been used and proven to be suitable. Therefore, Executable UML will be introduced and first experiences will be shown by an early prototype which realizes a typical scenario of industrial automation.
