Languages and tools for managing feature models

Feature models (FMs) are the de facto standard for modeling variability of software product lines. The research effort is still intensive and aims at increasing the adoption of FMs in practice. Integrated solutions that combine state-of-the-art techniques, languages, and tools are emerging. We give an overview of complementary languages, TVL and FAMILIAR, and tools for the purpose of supporting the management (e.g., configuration) of FMs. We report on practical applications of the languages and tools in different domains and for different purposes. Still, we are interested in applying our solutions to other contexts (e.g., industrial) in order to determine their applicability and possible adoption by practitioners.
