Welcome to OpenCM3 

This Open-Source-Project will adapt your UML-Modeling-Tool to your Domain Specific Language (DSL). 

The main problem in the field of domain-specific modeling is the missing support through the modeling tool. Even though UML offers possibilities for the extension of the UML profile by domain-specific information (stereotypes and tagged values), the support fom the modeling tools for the use of these extensions is only rudimental. Furthermore, the extensions are not suitable for storing structured information, like an attribute-mapping in the model, for example. The use of the extensions becomes extremely uncomfortable and error-prone, as there is no validation in the UML tool. Errors in the model, which might only become noticed in later project phases, would demand higher efforts for debugging. Apart from time-consuming coachings for new employees, the acceptance of the modeling language will be rather low.
