The success of open source applications such as Apache, Linux, and Sendmail spurred interest in this form of software, its development process, and its implication for the software industry. This interest is evident in the existing research being done to address various issues relevant to open source software and open source methodology. This paper proposes a research classification framework that: informs about the current state of open source software research, provides a formal structure to classify this research, and identifies future research opportunities.
