Definition of domain specific components in software product lines based on feature variability

This research proposes a preliminary methodology for the determination of a set of components to populate the domain model of a Software Product Line infrastructure. The approach is based on variability specifications that is rooted in Feature Models and reflected a variable component model: VCOSEML. An initial set of proposed components is modified with respect to the feature constraints and other design metrics such as coupling, cohesion, and size-oriented complexity. Modifications in the component set are refined through the iterative methodology, and an optimal set of components is tried to be achieved. The goal is to yield a set that supports reusability – to arrive at a more manageable and quickly converging design in terms of component assignments to required features. A case study is exploited in the validation of the approach
