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 Harz University of Applied Science.

Project members of the first phase:
At OvGU (DFG grant SA 465/49-1):

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

At Harz University of Applied Science (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 was

  • Prof. Dr. Thorsten Berger

Project members of the second phase (EXPLANT 2.0):
At OvGU (DFG grant SA 465/49-1):

  • Prof. Dr. Gunter Saake
  • M.Sc. Jacob Krüger

At the Harz University of Applied Science (DFG grant LE 3382/2-1):

  • Prof. Dr.-Ing. Thomas Leich
  • M.Sc. Sebastian Krieter

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).
