Synthesize software product line

In the development of a Software Product Line (SPL), it is useful to compare various products in order to identify reusable assets and synthesize them in an optimized way. Current differencing approaches provide the difference on a low level thus still leaves the SPL practitioner considerable manual synthesis work. This paper presents a comparison approach based on Common Variability Language (CVL), which is able to identify the difference on a higher conceptual level. We believe that our CVL Compare approach will offer better model comparison support in the context of identifying and synthesizing SPLs.
