Research on Variability Metamodeling Method

It is of key significance and reference value to provide variability for model-driven software development. Capturing the common feature and variable benefits a lot from the variability modeling which provides an approach of model reuse for constructing a family of application model. Based on the research that the variability mechanism of feature modeling and the deficiency of variability descriptions in MDA standard modeling languages, a variability metamodeling method is originated, which supports the variability specification such as atom and group variability by a UML profile mechanism, and the algorithms for variability verification and model transformation are developed. This method proves effective for reusing model contents based on variability modeling by the practice in a real project
