Describing the correlations between metamodels and transformations aspects

Metamodels are a key concept in Model-Driven Engineering. Any artifact in a modeling ecosystem has to be defined in accordance to a metamodel prescribing its main qualities. One of the most important artifact is model transformation that are considered to be the heart and soul of MDE and as such advanced techniques and tools are needed for supporting the development, quality assurance, maintenance, and evolution of model transformations. Several works propose the adoption of metrics to measure quality attributes of transformation without considering any metamodel aspects. In this paper, we present an approach to understand structural characteristics of metamodels and how the model transformations depend on corresponding input and target metamodels.
