Architectures for Software Product Lines

Product line-based software development can only lead to full success if it is recognized as an integrated concept, which involves all phases of the software engineering process. This project concentrates on architecture modelling for Software Product Lines. We have developed a top-level process for Software Product Line architecture modelling. Within the *domain engineering* initially the requirements for the entire Product Line Platform are collected together with the identified variability and afterwards compiled into a *requirements model* for the Product Line Platform, which among other things contains for example a *feature model*. This requirements model forms the basis for the top-level layer of the Product Line Platform architecture. Starting from this still abstract architecture layer, the PLP architecture gets more and more refined in further architecture layers. This procedure is according to the *Model Driven Architecture* (MDA) approach introduced by the OMG
