Composition of UML Described Refactoring Rules

Refactorings represent a powerful approach for improving the quality of software systems. A refactoring can be seen as a special kind of behavior preserving model transformation. The Object Constraint Language (OCL) together with the metamodel of Unified Modeling Language (UML) can be used for defining rules for refactoring UML models. This paper investigates descriptions of refactoring rules that can be checked, reused and composed. The main contribution of this paper is an algorithm to compute the description of sequentially composed transformations. This allows one to check if a sequence of transformations is successfully applicable for a given model before the transformations are executed on it. Furthermore, it facilitates the analysis of the effects of transformation chain and its usage in other compositions.
