Many companies develop software product lines-collections of similar products-by cloning
and adapting artifacts of existing product variants. Transforming such cloned product …

Abstract Software Product Lines (SPLs) are families of systems that share common assets
allowing a disciplined reuse. Rarely SPLs start from scratch, instead they usually start from a …

Abstract Context: Variant-Rich Systems (VRSs), such as Software Product Lines or variants
created through clone & own, aim at reusing existing assets. The long lifespan of families of …

Software product lines (SPLs) are families of related systems whose members are
distinguished by the set of features they provide. Over 2 decades of research and practice …

Software product line engineering is an efficient means to generate a set of tailored software
products from a common implementation. However, adopting a product-line approach poses …

Model merging is widely recognized as an essential step in a variety of software
development activities. During the process of combining a set of related products into a …

The notion of features is commonly used to maintain, evolve, reuse, or re-engineer a
software system. To this end, developers need to understand the features and their …

While the creation of new branches and forks is easy and fast with modern version-control
systems, merging is often time-consuming. Especially when dealing with many branches or …

Abstract Object-oriented Application Programing Interfaces (APIs) support software reuse by
providing pre-implemented functionalities. Due to the huge number of included classes …

Many software systems need to exist in multiple variants. Organizations typically develop
variants using clone&own---copying and adapting systems towards new requirements …
