Abstract: Providing variability supports for models is very important for model-driven software development practices. Variability modelling facilities capturing the commonness and difference among domain concepts and their features. Variability modelling provides an approach of reusing models for building a family of application models. After studying the variability mechanism of feature modelling and the deficiency of variability descriptions in MDA standard modelling languages, a variability metamodelling method is proposed. In the method, a UML profile for variability is built to support several kinds of variability, such as atom and group variability, etc. The Algorithms for variability verification and model transformation are developed. Being used in a real project, the method provides effective supports for reusing model contents based on variability modelling.
