Original Kurzfassung:
Model transformations play a key role in the vision of Model Driven Engineering. Thereby, the resolution of structural
heterogeneities between metamodels (MMs) represents the
key challenge. For this task, current approaches require the
definition of partly tricky, low-level recurring transformation
logic but neglect to offer reusable components. Moreover,
little attention has been paid to heterogeneities caused
by the concept of inheritance, although extensively used
in MMs. Therefore, we propose to specify model transformations
in a plug and play manner by a set of predefined mapping operators (MOps) representing a DSL to
resolve structural heterogeneities. For coping with inheritance
in MMs, we introduce an inheritance mechanism between
MOps allowing to reuse parts of the mapping definitions.
Moreover, dedicated MOps for resolving heterogeneities
when one MM comprises inheritance hierarchies
whereas the other one does not are presented, which are wellknown
problems in object-relational transformations and object-
oriented refactorings.
