Abstract. A Software Product Line (SPL) is a portfolio of similar software products that target a particular domain. SPL methodologies generally use Feature Modeling to express requirements including variability, and provide a prescribed way to develop particular products from reusable assets. These methodologies do not explicitly preserve design rationale, which is implicitly stated in the SPL architecture. Having a systematic, tool-enabler, scalable and evolvable method for generating family members is desirable. In this paper, we use Feature Configuration Models (FCM) as the DSL for specifying particular product requirements, and we apply MDE techniques for systematizing the process of product generation. We use model transformations for stating how the Product Architecture is built from the FCM, and for integrating the reusable components. Such transformations share a common but evolvable set of rules, and conform an explicit representation of the SPL rationale. We apply our approach for developing a Meshing Tool SPL.
