A.R.: Executing UML Models

Abstract. Software development evolution is a history of permanent seeks for raising the abstraction level to new limits overcoming new frontiers. Executable UML (xUML) comes this way as the expectation to achieve the next level in abstraction, offering the capability of deploying a xUML model in a variety of software environments and platforms without any changes. This paper comes as a first expedition inside xUML, exploring the main aspects of its specification including the action languages support and the fundamental MDA compliance. In this paper is presented a future new xUML tool called XIS-xModels that gives Microsoft Visio new capabilities of running and debugging xUML models. This paper is an outline of the capabilities and main features of the future application. Keywords: UML, executable UML, Model Debugging, Action Language. 1
