Modeling Software Kit (MOSKitt) is a FREE CASE tool, built on Eclipse, which is being developed by the Conselleria de Infraestructuras, Territorio y Medio Ambiente. Its main goal is to provide the necessary tools for supporting a complete Model Driven Software Development (MDSD) Process. To achieve such support MOSKitt has been endowed with a set of graphical model editors (such as BPMN, UML, User Interface Design or Data Base Design) and Model Transformations (M2M and M2T) that turn it not just as a Modeling Tool but also as a powerful environment to automate the full development process. In addition, MOSKitt's plugin architecture allows using MOSKitt as a real CAME environment. This feature enables specifying and implementing different software development processes based on the specific requirements of software company life cycles and processes.
