MDebugger: A Model-Level Debugger for UML-RT

Ideally, debuggers for Model-Driven Development (MDD) tools would allow users to 'stay at the model-level' and would not require them to refer to the generated source code or figure out how the code generator works. Existing approaches to model-level debugging do not satisfy this requirement and are unnecessarily complex and platform-specific due to their dependency on program debuggers. We introduced a novel approach to model-level debugging that formulates debugging services at model-level and implements them using model transformation. This approach is implemented in MDebugger, a platform-independent model-level debugger using Papyrus-RT, an MDD tool for the modeling language UML-RT.
