Traceability Visualization in Model Transformations with TraceVis

Model transformations are commonly used to transform models suited for one purpose (e.g., describing a solution in a particular domain) to models suited for a related but different purpose (e.g., simulation or execution). The disadvantage of a transformational approach, however, is that feedback acquired from analyzing transformed models is not reported on the level of the problem domain but on the level of the transformed model. Expressing the feedback on the level of the problem domain requires improving traceability in model transformations. We propose to visualize traceability links in (chains of) model transformations, thus making traceability amenable for analysis.
