WEESR and REVE 2022

10th International Workshop on Reverse Variability Engineering

12 September 2022, Graz, Austria

held in conjunction with SPLC2022 - 26th International Software Product Line Conference - September 12-16 2022


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.

Held in conjunction with

Submission details

REVE proceedings will be included in SPLC proceedings (Volume 2)

Submission types: Authors interested in participating in the workshop are requested to submit either:

  • Regular paper (max. 8 pages) that presents original research or industrial experience report
  • Short paper (4 pages) that describes sound new ideas and concepts that are under research or experimental studies at industrial settings.

Format: Submissions must adhere to the latest ACM Master Article Template.
Templates for Word and LaTeX are available at https://www.acm.org/publications/proceedings-template
Latex users are indicated to use the “sigconf” option, so they are recommended to use the template that can be found in "sample-sigconf.tex".
In this way, the following latex code can be placed at the start of the latex document:
\acmConference[SPLC’22]{26th ACM International Systems and Software Product Lines Conference}{12-16 September, 2022}{Graz, Austria}

Submission: All papers submitted to the workshop must be unpublished original work and must not have been submitted anywhere else for publication. Each paper will be reviewed by three PC members and accepted papers will be selected based on quality, novelty, and relevance to the workshop topic. At least one author should register and present the paper during the workshop.
Papers should be submitted via https://easychair.org/conferences/?conf=splc2022.

Keynote photo 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.
