The aim of this project is to establish a framework called TROPIC (Transformations on Petri Nets in Color) for developing model transformations which tackles these limitations. First, TROPIC allows to specify model transformations on different abstraction levels, providing both a declarative mapping language based on UML 2 component diagrams which hides implementation details, and derived from that, an executable transformation language using Coloured Petri Nets. Second, TROPIC facilitates reusability by providing an initial library of generic transformation operators which can be bound to arbitrary metamodels and by allowing to extend this library on demand with new, user-defined, transformation operators, optionally composed out of already existing ones. Finally, TROPIC overcomes the impedance mismatch by supporting a dedicated runtime model in terms of Coloured Petri Nets, allowing for a homogeneous representation of all transformation artefacts (i.e., models, metamodels and the transformation logic itself), which fosters understandability and debuggability of model transformations.
