Software Architectures and Open Source Software – Where can Research Leverage the Most?

Software architectures have been playing a central role in software engineering research for some years now. They are considered of pivotal importance in the success of complex software systems development. However, with the emergence of Open Source Software (OSS) development, a new opportunity for studying architectural issues arises. In this paper, we introduce accepted notions of software architectures (Section 2), discuss some of the known issues in OSS (Section 3), resulting in a set of aspects we consider to be relevant for future research (Section 4).
