Investigating the Use of Object-Oriented Design Patterns in Open-Source Software: A Case Study

During the last decade open source software communities are thriving. Nowadays, several open source projects are so popular that are considered as a standard in their domain. Additionally, the amount of source code that is freely available to developers, offer great reuse opportunities. One of the main concerns of the reuser is the quality of the code that is being reused. Design patterns are well known solutions that are expected to enhance software quality. In this paper we investigate the extent to which object-oriented design patterns are used in open-source software, across domains
