    • Community Development at the Apache Software Foundation BOSC 2010, Boston, July 2010 Open Bioinformatics Foundation Ross Gardler @rgardler rgardler@apache.org Vice President, Community Development The Apache Software Foundation
    • ● History of The Apache Software Foundation ● Accident or design? ● The Apache Way ● Flexibility and invariants ● Scaling the foundation ● From 8 to 2500+ ● Surviving the future ● A collection of projects or collaboration between experts?
    • History of the ASF
    • Founding of Apache ● Started as “Apache Group” (8 members) ● Resumed work on NCSA httpd in Feb 1995 ● UIUC put httpd in public domain, but essentially abandoned it ● Chose permissive licensing ● Informal corporate structure, until...
    • Creation of the Foundation ● Incorporated with 21 members in 1999 ● ~2,500 committers, 291 members, and 53 emritus members today ● Membership-based organisation ● 501(c)3 publish charity status
    • Apache's mission The Apache Software Foundation provides support for the Apache community of open source software projects. The Apache projects are characterised by a collaborative, consensus based development process, an open and pragmatic software licence, and a desire to create high quality software that leads the way in its field.
    • Apache's tagline We are more than a group of projects sharing a server, we are a community of developers and users
    • Or to put it another way... ● Let developers focus on what they do best ● Code ● Document (if only...) ● Foundation exists to do the rest ● “The Apache Way” ● Open development vs. open source ● All technical decisions about a project are made in public (mailing lists)
    • Indirect financial support ● Apache does not pay for development ● Voluntary contributions only ● Many (not all) developers are paid by a third- party to work on the project ● Foundation bears indirect support costs ● Infrastructure, legal, publicity, etc.
    • The Apache Way
    • We're a meritocracy ● Everyone has a voice ● Do stuff and get a vote ● Merit is not transferable between projects ● Merit across multiple projects or at foundation level earn you membership
    • Decision Making ● Who makes decisions? ● Community consensus via debate and code ● Occasionally a vote is required ● +1, +0, -0, -1 ● Everyone in the community has a vote ● “binding” vote given to committers ● All technical votes cast on public lists
    • Rule of Lazy Consensus ● Trusted parties can just get on with it ● They know when a change will be controversial ● State what you intend to do and why ● Start doing it ● If no-one objects to the idea commit the code ● There's always code review
    • Scaling the Foundation
    • Growth of the Foundation ● Started with just HTTP Server in 1995 ● The model “felt” repeatable ● Today, we have over 70 top-level projects ● >30 in Incubator ● It took over 15 years to get there... ● … but it wasn't smooth ...
    • Jakarta “Foundation” ● Jakarta: “umbrella” for all Java efforts ● Successful as a brand in its own right ● Tomcat, Ant, Struts, etc. ● Started to copy the foundation org structure ● “mini”-board... but problems arose... ● who was responsible?
    • Importance of Oversight ● Jakarta issues led to a lot of navel gazing ● Ultimately agreed upon an extremely flat organisational structure ● Very short communication lines ● Umbrella projects are bad! ● We killed jakarta: all projects became top-level
    • Board Oversight ● Projects submit quarterly board reports ● By far the most important board activity ● Looking for repeating community anti-patterns ● Emerging umbrella projects ● Undue commercial influence ● Stagnating community ● Etc. ● NOT concerned with technical issues
    • Foundation Structure ● Top-Level Projects ● Foundation ● Users ● Members ● Contributors – Cross-project community ● Committers ● Board ● PMC – Oversight – Technical management ● Foundation projects
    • What makes a good Apache project?
    • Community ● Diversity ● Minimum of 3 committers ● unrelated to one another outside the project ● Fully audited code ● CLAs on file ● No incompatible licences ● Practice The Apache Way –
    • Generic and Reusable ● Don't (just) open source a complete application ● Open source the component parts independently ● Encourage communities from outside your domain ● Get enhancements to your libraries from others ● Or maybe, you can contribute to someone elses

    • Surviving the Future
    • Can the ASF scale further? ● More projects mean ● Small overhead on foundation ● More volunteers at foundation level ● But... ● more opinions on what “The Apache Way” is ● more potential for abuse of ASF brand
    • Managing growing pains ● Flat structures give power to “newbies” ● Low barriers to entry ● No entrance “exam” ● Can result in the “blind leading the blind” ● But, hierarchy is inefficient ● Higher barrier to entry creates a hierarchy ● So how do we ensure “The Apache Way” survives? ● Without stagnating
    • The Apache Way has the answer ● Peer review is core to The Apache Way ● “Just get on with it, we'll object if necessary” ● Someone is watching ● Objections are supported by debate – That's how we learn ● Mentoring is a small step from peer review
    • The Incubator ● Incubates new projects ● More specifically new project communities ● Mentors guide the project team ● Teach The Apache Way
    • Community Development Project http//community.apache.org ● Google Summer of Code ● Code only ● Summer only ● Students only ● Apache Mentoring Project ● Any contribution ● Any time ● Anyone
    • Why do this in foundation projects? ● Let developers do what they do best: code ● But some volunteers want to help newcomers ● Good for recruiting ● Good for training ● Good for community ● Good for getting stuff done
    • Summary
    • Separation of Concerns ● Foundation ● Brand ● Infrastructure ● Legal ● Cross project community ● Projects ● Technical issues ● Project community
    • No leaders, just doers ● Give decision making power to the doers ● Use lazy consensus to avoid “management by committee” ● Anyone with sufficient merit can veto ● But they should never need to ● Consensus through discussion
    • Generalise ● Don't just open source a complete application ● Open source components of the application ● Most applications address a niche ● You are not unusual in this
    • Educate ● Apache projects are successful because of “The Apache Way” ● There are other ways ● But not in Apache ● Better to ensure newcomers understand ● Incubation for project communities ● Mentoring for individuals
