1 10 May 2005UNSDI Workshop - FAO-HQ - Italy Free and Open Source Software (FOSS) & OpenSDI Jeroen Ticheler

2 10 May 2005UNSDI Workshop - FAO-HQ - Italy Content  What is Software?  What is Free and Open Source Software?  Benefits and constraints of FOSS  OpenSDI  Conclusions

3 10 May 2005UNSDI Workshop - FAO-HQ - Italy What is Software?  Instructions that make hardware work  Programmers write scripts that can be understood by people and by compilers: the source code  Compiled software can not be fixed or adapted to user needs

4 10 May 2005UNSDI Workshop - FAO-HQ - Italy What is Software?  A key property is that it can be infinitely copied without any loss

5 10 May 2005UNSDI Workshop - FAO-HQ - Italy Open Source versus Closed Source Software  Most prominent example

6 10 May 2005UNSDI Workshop - FAO-HQ - Italy Open Source versus Closed Source Software  Source code is often the most secret property  Open Source software provides access to the source code of an application

7 10 May 2005UNSDI Workshop - FAO-HQ - Italy Think of Source Code as LEGO ® Pieces LEGO ® Metaphor as used in “Towards a Free and Open Source Spatial Data Infrastructure.” C. Holmes et. al. - 2005

8 10 May 2005UNSDI Workshop - FAO-HQ - Italy You Can Build New Constructions

9 10 May 2005UNSDI Workshop - FAO-HQ - Italy These Might Be Simple Constructions

10 10 May 2005UNSDI Workshop - FAO-HQ - Italy Or More Complex Ones

11 10 May 2005UNSDI Workshop - FAO-HQ - Italy Much depends on the users

12 10 May 2005UNSDI Workshop - FAO-HQ - Italy You can use a solid basis

13 10 May 2005UNSDI Workshop - FAO-HQ - Italy And repaint it, changing the look and feel

14 10 May 2005UNSDI Workshop - FAO-HQ - Italy An Example  OpenOffice* was translated into Swahili in four months in Tanzania.  The project leader said: º "we clearly show that with free and open source software we can do in four months what proprietary software has never done for the Swahili speakers." * A FOSS alternative to Microsoft Office

15 10 May 2005UNSDI Workshop - FAO-HQ - Italy Or You Could Go Much Further

16 10 May 2005UNSDI Workshop - FAO-HQ - Italy UNEP’s custom interface on GeoNetwork OpenSource (under development)

17 10 May 2005UNSDI Workshop - FAO-HQ - Italy Making Sure The Software Works For Its Users

18 10 May 2005UNSDI Workshop - FAO-HQ - Italy Possible Constraints of Open Source  Lack of technical support? º The first support comes from the community º Successful projects usually have companies or developers in their community offering commercial technical  User Oriented Documentation  No Marketing Budget

19 10 May 2005UNSDI Workshop - FAO-HQ - Italy Benefits of Open Source Software  Free to use and distribute  Free to choose (no vendor lock-in)

20 10 May 2005UNSDI Workshop - FAO-HQ - Italy Benefits of Open Source Software  Software can be developed or changed by everybody  Software is protected by a copyright, often referred to as copyleft, ensuring its freedom

21 10 May 2005UNSDI Workshop - FAO-HQ - Italy Benefits of Open Source Software  Ever-increasing Return on Investment º Most improvements come back to the whole community  User feedback º Features that a user may not know º Bug reports

22 10 May 2005UNSDI Workshop - FAO-HQ - Italy An Example

23 10 May 2005UNSDI Workshop - FAO-HQ - Italy Benefits of Open Source Software  Strong tendency towards compliancy to international standards

24 10 May 2005UNSDI Workshop - FAO-HQ - Italy Building Capacity in Countries  Money otherwise spend on license fees can go exclusively towards developing skills and local capacity

25 10 May 2005UNSDI Workshop - FAO-HQ - Italy Some GeoFOSS  235 different projects listed on freegis.net  MapServer - internet map server º Standards:OGC WMS, WCS, WFS  GeoServer - internet feature server º Standards: OGC WFS, WFS-T, WMS  GeoTools - Java toolkit º Standards: OGC WMS  GeoNetwork - metadata and catalog tools º Standards: ISO19115, OGC Catalog  uDig - client toolkit

36 10 May 2005UNSDI Workshop - FAO-HQ - Italy Conclusions Enormous potential for developing countries º No need for software piracy º Develop its own software and servicing industry º Currency stays in the country º Freedom to choose º Freedom to distribute
