The IEEE International Workshop on Quality and Architectural Concerns in Open Source Software (QACOS 2008)

The IEEE International Workshop on
Quality and Architectural Concerns in Open Source Software (QACOS 2008)



The Open Source Software (OSS) movement, which originated from a pragmatic need to share code among individuals has grown to become a major force behind inter-organizational reuse of platforms, components and code. However, there are several research questions that remained unanswered. Some of these questions are:

  • What are the challenges of quality assurance of open source components?
  • How can the cost and impact of using low quality components be measured?
  • What is known about the architectural approaches that support seamless integration of open source components?
  • What is currently known about the strengths and limitations of quality assurance and quality assessment approaches being used for selecting open source components?
  • How to improve architecture and quality information exchange between open source communities and OS component users?

This workshop aims at bringing together both researchers and practitioners from open source software, software architecture, and software quality backgrounds to discuss the importance and challenges of quality assurance, quality assessment, and architectural concerns involved in selecting and using open source components in large scale software intensive systems. The overall goal of the workshop is to develop a common research agenda based on inputs from three communities to identify the research issues that should be addressed in the short to long term. This event will also provide a platform to present mature and ongoing research aimed at:

  • Bridging the gap between practitioners (open sources and commercial) and researchers on the selection, use and/or integration of open source components into in-house software;
  • Bridging the gap between open source, software quality and architecture-centric approaches.

The workshop solicits submissions that encompass quality and architectural issues in developing and using open source software.


Researchers and practitioners from software quality, software architecture and open source software (OSS) are invited to propose papers and to attend the workshop.

We aim at attracting participants both from research and industry in order to ensure that both communities can share their knowledge and experiences about the state-of-the-art and state-of-the-practice of quality assurance approaches and architectural consideration in the development, selection, evaluation, and use of open source software.

Original papers will be considered. All submitted papers will be reviewed by the program committee according to its originality, significance, correctness, presentation, and relevance. We encourage authors to present position papers on practical studies and experiments, critiques of existing work, emerging issues, and novel ideas under development.

Papers must be submitted electronically via the QACOS 2008 Submission Page. Manuscripts will be limited to 6 pages including all figures, tables, and references. The format of submitted papers must follow the IEEE conference proceedings guidelines (i.e., 8.5" x 11", Two-Column Format (PDF: instruct.pdf; DOC: instruct.doc); Layout Guide (PDF: format.pdf; DOC: format.doc; all under

All accepted papers will be published in the electronic conference proceedings by the IEEE Computer Society, indexed through INSPEC and EI Index (Elsevier's Engineering Information Index), and automatically included in the IEEE Digital Library. At least one of the authors of each accepted paper must register as a full participant of the workshop for the paper to be included in the proceedings. Each accepted paper must be presented in person by (one of) the author(s).
