Extracting and Evolving a Software Product Line from Existing Web-based Systems: An Experience Report

Abstract

This paper presents an experience report of extraction and evolution of software product lines (SPLs) from existing web-based systems. We describe the activities to succesfully refactor and evolve an web-based system of management of university rooms and laboratories by promoting the management and modularization of their variabilities. Several lessons learned are derived from that experience, includying the proposal of a method for the extraction and evolution of SPLs, as well as strategies for variability refactoring.
