ABSTRACT
Software Product Lines (SPLs) are a successful approach to software reuse in the large. Even though tools exist to create SPLs, their evolution is widely unexplored. Evolving an SPL manually is tedious and error-prone as it is hard to avoid unintended side-effects that may harm the consistency of the SPL. The main contribution of this paper is the conceptual basis of a system for the evolution of model-based SPLs, which maintains consistency of models and feature mapping. As further contribution, a novel classification is introduced that distinguishes evolutions by their potential to harm the mapping of an SPL. In addition, multiple remapping operators are presented that can remedy the negative side-effects of evolutions in order to co-evolve the feature mapping. Finally, an implementation of the evolution system in the SPL tool FeatureMapper is provided to demonstrate the capabilities of the presented approach when co-evolving models and feature mapping of an SPL.

Managing evolution in software product lines: a model-checking perspective
VaMoS '12: Proceedings of the 6th International Workshop on Variability Modeling of Software-Intensive SystemsIn Software Product Line (SPL) engineering, similar software products are developed in families rather than individually. Developing similar software at once leads to new challenges. In particular, the model checking problem for SPL is harder because it ...
Refactoring delta-oriented software product lines
AOSD '13: Proceedings of the 12th annual international conference on Aspect-oriented software developmentDelta-oriented programming (DOP) is an implementation approach to develop software product lines (SPL). Delta-oriented SPLs evolve over time due to new or changed requirements and need to be maintained to retain their value. Refactorings have been ...
Co-evolution Analysis for Software Product Lines
ENASE 2015: Proceedings of the 10th International Conference on Evaluation of Novel Approaches to Software EngineeringThe purpose of our approach is to study the co-evolution of the platform and the products of software product
lines. Because the platform must be able to derive all the family products, products are not allowed to evolve
independently from the plateform,...
