Predefined composite operations are handy for efficient modeling,
e.g., for the automatic execution of refactorings, and for the introduction
of patterns in existing models. Some modeling environments
provide an initial set of basic refactoring operations, but hardly offer any
extension points for the user. Even if extension points exist, the introduction
of new composite operations requires programming skills and
deep knowledge of the respective metamodel.
In this paper, we introduce a method for specifying composite operations
within the user's modeling language and environment of choice.
The user models the composite operation by-example, which enables the
semi-automatic derivation of a generic composite operation specification.
This specification may be used in further modeling scenarios, like model
refactoring and model versioning. We implemented the approach in the
Operation Recorder and performed an evaluation by defining multiple
complex refactorings for UML diagrams.
