Open Source Software Development

UCI research in open source software development focuses on empirically-based studies of the processes, practices, and communities that develop open source software and related artifacts. Ethnographic and virtual enthnographic research methods are employed in the field studies of open source software development in communities that include those centered on Internet infrastructure, X-Ray astronomy and deep space imaging, networked computer games, and academic software design research.
