EXtracting Product Lines from vAriaNTs (EXPLANT)

Project Summary

Software product lines (SPLs) enable systematic reuse and variability management of software artifacts. In practice, software is often reused in an ad-hoc manner by simply copying a system and adapting it to new requirements (called clone-and-own). Due to the lack of automatic and systematic management of artifacts, propagating changes (e.g., for bug fixing) and replacing functionality becomes expensive and error-prone.

The goal of our project is to migrate cloned product families into a structured, modular product line.  Using code clone detection, architectural analyses, and domain knowledge we aim for a semi-automatic, semantics-preserving, stepwise transformation. In each step, a small semantics-preserving the code and/or the feature model is performed.

Cooperations and Funding

Project EXPLANT is funded by the German Research Council (Deutsche Forschungsgemeinschaft (DFG)) under the grants SA 465/49-1 and LE 3382/2-1. It is a cooperation between the Otto-von-Guericke-Universität Magdeburg (OvGU) and the Hochschule Harz.

Project members at the OvGU (DFG grant SA 465/49-1):

  • Prof. Dr. Gunter Saake
  • Dipl.-Inf. Wolfram Fenske

Project members at the Hochule Harz (DFG grant LE 3382/2-1):

  • Prof. Dr.-Ing. Thomas Leich
  • M.Sc. Jacob Krüger

Since October 2017, Jacob Krüger attends Chalmers University of Technology for a research visit. The main purpose is to foster cooperations with industrial partners.  Jacob Krüger's advisor at Chalmers University is

Awards

We received several awards that are and will be reported on in academic and popular media:

  • Hugo-Junckers award 2016 as innovative alliance for FeatureIDE that we use and extend in our project (10,000 EUR).
  • Best paper award at the International Conference on Generative Programming 2017 (GPCE'17) for Dipl.-Inf. Wolfram Fenske for the paper How Preprocessor Annotations (Do Not) Affect Maintainability: A Case Study on Change-Proneness.
  • Research Award of the Wernigeröder Stadtwerkestiftung 2017 for M.Sc. Jacob Krüger for the article Composing Annotations Without Regret? Practical Experiences Using FeatureC (3,000 EUR).
