Abstract

The open variability of software product line ecosystems allows customers and third party organizations to create extensions to a system which may refine the variability model. In this paper we will describe an approach to evolution support, which was developed in the context of one specific company, HIS GmbH. However, the approach is much more generic than this. In particular, it is based on the formalization of modifications to configuration values and constraints on both the model and the data in the context of the evolution of multi-level configurations. Our approach supports the identification of inconsistencies in evolution.
