  1. Open Source Software Communities - Lessons LearntImed Hammouda, adjunct professorAlexander Lokhman, researcherTampere University of Technology

  2. Open Source vs. Free Software Free software (1983) is: A philosophy A social movement FSF “Stallmanism” Open source (1998) is: A business model A development methodology OSI “Raymondism” Both approaches share a common vision on access to source code Loads of ready-made systems available in the Internet for various purposes in source form 2 16.7.2014

  3. Open Source – The Community Volunteer developers Non-profit organization Sponsors Commercial enterprises Different types of communities (members) Volunteer Ideology, freedom, sharing Company-based Business, funded developers Mixed Different types of communities (organization) Linux: Project centric MySQL: Business centric Eclipse: Foundation centric

  4. Community Contribution: Debian

  5. Onion Structure of FLOSS Communities Onion structure Linux kernel

  6. Becoming a Contributor - Eclipse New committers are voted in by the existing committers on a project. Based on meritocracy: Prove your abilities before you can become a committer. Building a good reputation with the existing committers Demonstrating skills to the existing team Asking a current project committer to sponsor you as a committer Going through an election process, defined in each top-level project's charter Best way to start contributing to Eclipse: Well-formed bug reports Feature requests Code enhancements

  7. Community Building: Dimensions Community Existing communities Community spirit Community support • Process • Patch handling • Governance model • Release management • Infrastructure • Version control • Bug tracking • Documentation • Software • Code standards • Best practices • Quality attributes • Marketing • Target communities • Marketing models • Viral marketing • Legality • Licensing type and scheme • Legal clearance • Trademarks

  8. Community Building: Intended Community Community type: Company based Volunteer Mixed Core group: Closed Open Structure: Independent community Part of an existing community An ecosystem of related smaller communities

  9. Community Building: Stakeholders Interested parties Open source communities & developers FAO and pilot countries Core

  10. Community Building: Existing Communities
