Variability modeling in model-driven software product line engineering

This paper describes an approach for modeling variability in software product lines that are developed, and later evolved, using model-driven software product line development. This paper describes variability management in UML based multiple-view models of the software product line, which consist of developing use case and feature models during requirements modeling, static and dynamic models during analysis modeling, and component-based software architectures during design modeling. This paper also describes an underlying multiple-view meta-model for the software product line, with consistency checking between the multiple views.
