Kirill Khistyaev 4/19/2011 Open Source Software Development Processes
Introduction to Open Source Software (OSS) • General description of OSS Development Process (OSSDP) • OSSDP in Science (Academia) • Conclusion Outline 2
Open Source Software (OSS) is a software whose source code may be freely studied, changed, improved and redistributed with few restrictions. Introduction 3
Linux • Apache • Perl, Python, PHP, etc. languages • MySQL • Mozilla Firefox • Eclipse • …. Introduction: Examples of OSS 4
Nowadays many commercial organization have started to look towards OSS and OSSDP as a way to minimize their development efforts. Introduction 5
Traditional software development is like building a cathedral “carefully crafted by individual wizards or small bands of mages working in splendid isolation” • OSSDP is like “a great babbling bazaar of differing agendas and approaches” Raymond, Eric S. (2000-09-11). "The Cathedral and the Bazaar". http://www.catb.org/~esr/writings/cathedral-bazaar/cathedral-bazaar/index.html OSS Development Process 6
Developers are end-users of the system • Early releases • Frequent Integration • Several versions • High modularization • Dynamic decision making structure OSS Development Process 7
User • Developer • Committer • Manager • Infrastructure maintainer *Jacques Lonchamp, Open Source Software Development Process Modeling, in Software Process Modeling, S.T. Acuna, N. Juristo (Eds), Springer, 2005, pp 29-64. OSSDP: Process Roles 8

OSSDP is the most suitable method for software development in academic environment • Typically non-commercial • Collaboration of many distributed groups OSSDP in Science 12
OSS is an important part of software world • OSSDP process allows to develop successful projects • OSSDP has significant differences from commercial software developments • OSSDP is well suitable for scientific software Conclusion 13
