2. Arnulf Christl, President OSGeoOSGeo Open Source Geospatial Foundation (OSGeo) Athens 19 th June 2009 2 Agenda 1.Introduce the Concepts behind Free Software and Open Source 2.The Inner Functioning of Open Source Communities 3.OSGeo in a Nutshell 4.The Software Projects 5.Case Study: The German Online Pollution and Transfer Registry

3. Arnulf Christl, President OSGeoOSGeo Open Source Geospatial Foundation (OSGeo) Athens 19 th June 2009 3 ● Open Source is a development methodology that aims at making all processes transparent. ● The central paradigm is to "Publish Early and Release Often". This will help to "build" [1] a community of high interaction. ● Development is coordinated through roles. Roles must be managed by a clear governance model. ● Good Open Source projects are highly organized and trunk commit access is restricted to well known developers. ● Public code repositories, bug and issue trackers, mailing lists, etc. are essential to "grow" [1] professional communities. [1] communities cannot be "built", "managed" or "grown". They need to grow by themselves. Open Source project management can only facilitate and enable communities. Open Source Development

4. Arnulf Christl, President OSGeoOSGeo Open Source Geospatial Foundation (OSGeo) Athens 19 th June 2009 4 Free Software Licensing ● Free Software describes a software licensing model ● Open Source code is a precondition to Free Software ● There are several types of Open Source Software licenses, some more restrictive some more relaxed ● Common to all Open Source licenses are the user's rights to: 1.run any number of copies of the software 2.pass on copies of the software including the license and copyright notice 3.look into the code, understand it and modify it to suit one's needs 4.pass on modified versions of the code

5. Arnulf Christl, President OSGeoOSGeo Open Source Geospatial Foundation (OSGeo) Athens 19 th June 2009 5 Copyright, Licenses and the Copyleft Myth FOSS licenses protect software from becoming proprietary. The legal background of the strong protection of the GNG is straight forward: "To copyleft a program, we first state that it is copyrighted; then we add distribution terms, which are a legal instrument that gives everyone the rights to use, modify, and redistribute the program's code or any program derived from it but only if the distribution terms are unchanged. Thus, the code and the freedoms become legally inseparable." [1] Copyleft is not a virus but a vaccination. [1] from: http://www.fsf.org/licensing/essays/copyleft.html

6. Arnulf Christl, President OSGeoOSGeo Open Source Geospatial Foundation (OSGeo) Athens 19 th June 2009 6 Understanding Open Source ● Free Software is not anti-business. ● -> Instead it is a business enabler by making code and software widely available. ● Free Software is not unlicensed software. -> Instead it is a licensing model. ● Open Source does not mean code-anarchy. -> Instead there is transparent governance processes and consens on strategy. ● Open Source is not insecure. -> instead it allows for highest security due to code and process transparency.

7. Arnulf Christl, President OSGeoOSGeo Open Source Geospatial Foundation (OSGeo) Athens 19 th June 2009 7 Adopting Open Source ● Free Software needs customization. ● ->...just as any proprietary spatial system. ● Free Software is not incomplete. ->...do not confuse Open Source with Freeware or Vaporware. ● Open Source is not unstable. -> Instead you can choose between stable and bleeding edge yourself. ● Open Source is not as good as... -> Open Source is better than...

8. Arnulf Christl, President OSGeoOSGeo Open Source Geospatial Foundation (OSGeo) Athens 19 th June 2009 8 Stop This type of discussion does not get uns anywhere

9. Arnulf Christl, President OSGeoOSGeo Open Source Geospatial Foundation (OSGeo) Athens 19 th June 2009 9 Open Source Software Communities ● Every Open Source Community and project is special and unique. ● Open Source software development follows complex social and technical processes. ● Read Karl Fogel's Producing OSS (http://producingoss.com/)http://producingoss.com/ ● Publishing early is good but can also confuse users. ● High responsiveness results in many releases making production more difficult ● The distinction between user and developer blurs. ● The antagonism between vendor and buyer dissolves.

16. Arnulf Christl, President OSGeoOSGeo Open Source Geospatial Foundation (OSGeo) Athens 19 th June 2009 16 The Need for a Legal Entity ● Professional users and enterprises alike need organized legal entities that they can trust to secure investments. ● In 1999 the Apache Foundation emerged from a group of developers who started working on the Apache Server in 1995. ● Similarly, in 2006 the Open Source Geospatial Foundation (OSGeo) was founded as a legal entity by a diverse community of software developers and users.
