A feature interaction algebra (FIA) is an abstract model of features, feature interactions, and their compositions. A structured document algebra (SDA) defines modules with variation points and how such modules compose. We present both FIA and SDA in this paper, and homomorphisms that relate FIA expressions to SDA expressions. This leads to mathematically precise formalizations of fundamental concepts used in software product lines, which can be used for improved FOSD tooling and teaching… CONTINUE READING
