Advances in communication devices and technologies are dramatically expanding our communication capabilities and enabling a wide range of multimedia communication applications. The current approach to develop communication-intensive applications results in products that are fragmented, inflexible and incapable of responding to changing end-users’ communication needs. These limitations have resu...

syntaxes of DSMLs partially define language semantics through their underlying structure and the vocabulary naming concepts and relationships. Unfortunately, such semantics may sometimes be ambiguous, since different engineers may have different understanding of a single model. Therefore, in order to have equal and non-ambiguous understanding, it is essential to define in a precise and non-ambi...

The TOPCASED project aims at developing an open source CASE environment for critical applications and systems development. Its main benefits should be to perpetuate the methods and tools for software development, minimize ownership costs, ensure independence of development platform, integrate, as soon as possible, methodological changes and advances made in academic world, be able to adapt tool...

With the emerging concept of model transformation, information can be extracted from one or more source models to produce the target models. The conversion of these models can be done automatically with specific transformation languages. This conversion requires mapping between both models with the help of dynamic hash tables. Hash tables store reference links between the elements of the source...

In model-driven engineering (MDE), software is developed based on models which hence constitute the central artifacts in the software development process. Consequently, tools supporting MDE, such as model editors, interpreters, and debuggers are crucial in MDE. For developing such tools efficiently, modeling languages have to be defined formally. While for formally defining a modeling language’...
