Feature Diagrams and their Transformations: An Extensible Meta-model

Feature models represent the variability and commonality of software product lines and permit the configuration of each specific application to be selected. We use a hypergraph based formalism to define an extensible and comprehensive feature meta-model. As a result, we readily can build a set of modeling tools compatible with the different flavors of these diagrams. Finally, automatic transformations of feature diagrams into UML models of the product line architecture are defined to register model traceability.
