Domain-Specific Modeling and Code Generation for Product Lines

Current modeling languages provide surprisingly little, if any, support for product line development. They are either based on the code world using the semantically well-defined concepts of programming languages (e.g. UML, SA/SD) or based on an architectural view using a simple component-connector concept. In both cases, the languages themselves say nothing about a product family or its variants. This situation could be compared to that of a programmer being asked to write object-oriented programs where the language does not support any object-oriented concepts.
