The embedded real-time software systems encountered in applications such as telecommunications, aerospace, and defense typically tend to be large and extremely complex. It is crucial in such systems that the software is designed with a sound architecture. A good architecture not only simplifies construction of the initial system, but even more importantly,(More)

UML includes special extensibility mechanisms, which are used to define domain-specific modeling languages that are based on UML. These mechanisms have been significantly improved in the latest versions of UML. Unfortunately, there is currently a dearth of published material on how to best exploit these capabilities and, consequently, many UML profiles are(More)

This paper gives a short overview of model-driven development - an approach to software development in which high-level models play a fundamental role. First, the problems that plague current programming approaches are analyzed. This is followed by a short description of the essential features of model-driven development and the potential benefits that it(More)
The Unified Modeling Languaget (UMLt) industry standard has recently undergone a major upgrade, resulting in a revision called UML 2. The primary motivation for this revision was to make UML better suited to model-driven developmente (MDDe), an approach to software development in which software models play a vital role. This requires a modeling language(More)
This chapter outlines Papyrus, a tool for graphical modeling of UML2 applications. It is an open-source project, designed as an Eclipse component, and is based on the existing EMF-based realization of the UML2 meta-model. The goal of this open-source project project is twofold. First, it aims at providing a complete, efficient, robust, and methodologically(More)
This paper provides an overview of the foundations of the run-time semantics underlying the Unified Modeling Language as defined in revision 2.0 of the official OMG standard. One of the problems with the format used for that standard is that the information relating to semantics is scattered throughout the text making it difficult to obtain a global(More)
