A Tool Environment for Managing Families of Model Transformation Rules

Model transformation systems often contain families of rules that are substantially similar to each other. Variability-based rules are a recent approach to express such families of rules in a compact representation, enabling the convenient editing of multiple rule variants at once. On the downside, this approach gives rises to distinct maintenance drawbacks: Users are required to view and edit presence conditions. The complexity and size of the resulting rules may impair their readability.
