Abstract: | Model driven engineering (MDE) of software product lines (SPLs) merges two increasing important paradigms that synthesize
programs by transformation. MDE creates programs by transforming models, and SPLs elaborate programs by applying transformations
called features. In this paper, we present the design and implementation of a transformational model of a product line of
scalar vector graphics and JavaScript applications. We explain how we simplified our implementation by lifting selected features
and their compositions from our original product line (whose implementations were complex) to features and their compositions
of another product line (whose specifications were simple). We used operators to map higher-level features and their compositions
to their lower-level counterparts. Doing so exposed commuting relationships among feature compositions in both product lines
that helped validate our model and implementation. |
