Introduction

Software Product Line (SPL) migration remains a challenging endeavour

From organizational issues to purely technical challenges, there is a wide range of barriers that complicates SPL adoption.
This workshop aims to foster research about making the most of the two main inputs for SPL migration:
1) domain knowledge and 2) legacy assets.
Domain knowledge, usually implicit and spread across an organization, is key to define the SPL scope and to validate the variability model and its semantics.
At the technical level, domain expertise is also needed to create or extract the reusable software components.
Legacy assets can be, for instance, similar product variants (e.g. requirements, models, source code etc.) that were implemented using ad-hoc reuse techniques such as clone-and-own.
More generally, the workshop REverse Variability Engineering (REVE) attracts researchers and practitioners contributing to

processes, techniques, tools, or empirical studies related to the automatic, semi-automatic or manual extraction or refinement of SPL assets.

Keynote
Serge Demeyer
Professor at the University of Antwerp (Department of Mathematics and Computer Science) and the spokesperson for the NEXOR research consortium.
His main research interest concerns software evolution, more specifically how to strike the right balance between reliability (striving for perfection) and agility (optimising for adaptability). He is involved in a few start-ups consulting his expertise on software architecture and test automation.
Social Coding Platforms Facilitate Variant Forks
Social coding platforms centred around git provide explicit facilities to share code between projects: forks, pull requests, cherry-picking to name but a few. Variant forks are an interesting phenomenon in that respect, as it permits for different projects to peacefully co-exist, yet explicitly acknowledge the common ancestry. The phenomenon of variant forks is quite common: in a recent study we found more than 400 open source projects originating from a common code-base. In this keynote we share our insights on the phenomenon of variant forks on social coding platforms. First, we report the results of an exploratory qualitative analysis on the motivations for creating variant forks. Next we illustrate how bug fixes may (should?) be transferred from one variant to another. As such we hope to inspire researchers to study the phenomenon of variant forks.
