QVT is the standard language sponsored by the OMG to specify model-to-model transformations. It includes three different languages, being QVT-Relations (QVT-R) the one with higher-level of abstraction. Unfortunately, there is scarce tool support for it nowadays, with incompatibilities and disagreements between the few tools implementing it, and lacking support for the analysis and verification of transformations. Part of this situation is due to the fact that the standard provides only a semi-formal semantics for QVT-R. In order to alleviate this situation, this talk will present a semantics for QVT-R through its compilation into Coloured Petri nets. The theory of Coloured Petri nets provides useful techniques to analyse transformations (e.g. reachability, model-checking, boundedness and invariant analysis) and to determine their confluence and termination given a starting model. The talk will also show how CPNTools can be used for the execution, debugging, verification and validation of QVT-R transformations. This is automated through a tool chain that transforms QVT-R specifications and their input models into the input format of CPNTools, and then exports and visualizes the transformation results back as models.
