At the same time, the ability to retrace the engineering process is animportant success factor for software projects. In MDE, however, such traceabil-ity is often impeded by the inadequate management of model evolution. Althoughmodels have a very fine-grained structure, their different revisions and variantsare prevalently managed as monoliths in a file-based software configuration man-agement (SCM). This causes the identification problem: if the fine-grained ele-ments are not assigned with globally unique identifiers, we cannot identify themover time.
