A design of a configurable feature model configurator

Our feature configuration tool S2T2 Configurator integrates (1) a visual interactive representation of the feature model and (2) a formal reasoning engine that calculates consequences of the user’s actions and provides formal explanations. The tool’s software architecture is designed as a chain of components, which provide mappings between visual elements and their corresponding formal representations. Using these mappings, consequences and explanations calculated by the reasoning engine are communicated in the interactive representation.
