•A community of your peers

• People who understand you!

• Great cross project code sprints

• Assistance in building community

• Marketting to help you ﬁnd users

• Incubation can help with Open Development


Are you threatened?
• Foundations offer some safety

• Incubation review to check your code is in the clear

• OSGeo has healthy body of prior art

• An area where we collaborate with other foundations:

• Our focus is on fostering spatial software and promoting use

• We are not a strict “IP” machine


Are you confused?
• OSGeo has a range of mapping experts

• Helpful, engaging and educational

• Great for collaboration on tough problems

• Do the mapping experts make you more confused?

• Wide range of developers can help translate “expert” advice

• If you are confused how do you know you are confused?


Are you broke?

• OSGeo participation is free

• Sign up to an email list or committee and get involved!

• Charter members are nominated yearly

• Board members are voted on by Charter members


Who Pays?
• We would like to thank our Sponsors!


Want to get back to coding?
• Perfect - Foundations are here to help with everything else

• Lonely: Community

• Threatened: Protection

• Confused: Experts available (and developers to translate)

• Broke: OSGeo Participation is free

• Funded: Through Sponsorship


We are not alone
• locationtech.org • incubator.apache.org/sis

• Eclipse Foundation • Apache Foundation Spatial
LocationTech Industry Information System
Working Group
• Currently in Incubation
• Announcement scheduled

Do I have to Choose?

• The OSGeo Foundation does not limit your options

• Our mandate is to help and promote

• OSGeo does not need control of the code

• Indeed we often work with other foundations

• As we do not want to be experts on license, trademarks,
intellectual property, etc...


The Badge
Seeing beyond Branding


User Beneﬁts
• What “OSGeo Project” means for you: Trust!

• It is actually open source!

Incubation Checklist


Open
Project has open, active and healthy
user and developer community


Open and Public
• Open Source License

• Anything approved by the Open Source Initiative

• Open communication channels

• Email, Issue Tracker, Conference Call (with minuets)

• Open decision making process

• Example: Project Steering Committee


Community
• Active

• Community of users and developers

• Support each other

• Example: Collaboration during release

• Healthy

• Long term viability

• Participation from range of developers / organisations


Copyright and License
Check a project has obtained the ability to release


Source Code License

• Source code available under an open source license

• Any Open Source Initiative approved license is ﬁne with us
(we are not the license police)


Documentation License
• Documentation available under an open license

• When Citation is not enough!

• Give authors the same ability to “remix” we enjoy as
developers - really helps when pulling together course packs
and training material.

• Example: Creative Commons

• Tip: Contact Regional OSGeo Chapters for help with
translation and internationalisation


Sanity Check

• We ask for a Provenance Review

• Check source code

• Check documentation

• Check data

• Do you know who gave it to you?


Contributors
• Do you know who gave you the code?

• List contributors:

• Either as copyright holders; or

• Ask for a “Code Contribution” agreement

• This is really handy if you ever have to change license!

• The Foundation can act as a legal entity if required


Process
Version control, issue tracker, decisions


Version Control
• Formally “Conﬁguration Management”

• Anything will do: subversion, git, CVS

• Think of the users: If they run across a copy of your
application from three years ago - will you be able to help
them? Will they be able to help themselves?

• Tip: The OSGeo foundation is “relaxed” and asks projects to
choose the hosting option that best suits their community.
(Indeed some of our projects have migrated to “github”)


Issue Tracker

• Issue trackers are great for communicating, both problems, but
also the context (and eventual ﬁx)

•I know: This is one step up from email

• OSGeo Foundation can offer “Trac” but our projects are all
over the map (from codehaus to github)


Management

• Not just “how to build” but also “how decisions are made”

• This is the key point of “open development” where we can
conﬁdently recommend a project is open to participation

• Public communication channels
(Email, IRC, meeting with sponsors, breakfast ...)

• Many of our projects follow a variation of the Apache Process
(project steering committee and votes of +1, 0 and -1)


Documentation
Don’t be scared, looking for a basic quickstart
(and enough for a volunteer to help out)


User Documentation

• Basic Quickstart

• Guide new user through performing “core functionality”

• That was not so bad was it?


Developer Documentation

• Checkout and build instructions

• Code documentation

• Publish API if possible (Javadocs, Sphinx, etc...)

• Comments!


Documentation Questions

• Q: How to submit a patch or ﬁx?

• Q: How to contribute a new feature?


Release
Real artists ship


Release Instructions

• Do you have some instructions on how to release?
(any automated or manual testing?)

• Informal:

• Verify nightly build passed tests and Tag

• Formal:

• Code freeze, release candidates, tag in version control


Testing Instructions

• Just tell us what you actually do :-)

• Automated “Jenkins” build server, with core modules at 80%
test coverage

• Make a Release Candidate, and it can still perform the
quickstart instructions it is “good to go”


Release Questions

• Q: Can a volunteer follow the instructions to make a release?

• Q: Are you sure?

• Q: Would you let them upload to the project site?


Incubation Projects
We are working on it!

• The OSGeo Board is responsible for running the foundation,
they are elected by the Charter Members annually.

• Charter members by public nomination annually

• Project Ofﬁcer

• Volunteer contact point

• Can change ofﬁcer as needed


Marketting Committee
Volunteers from all over the world

• The Marketting Committee is very active, getting information out to
the public, helping prep material for conferences and taking charge of
publicity.

• Some project details and documentation

• Application Overview

• Application Quickstart

• Logo

• Graphic Image (ie screen shot or layer diagram)

• Recommend: Stable release they can point users at
(DebianGIS, OSGeo-Live, osgeo4w, website...)

System Admin Committee
Infrastructure help if you need it


System Admin Committee
• That is “sudo” to you and me, the System Admin Committee
is responsible for foundation infrastructure.

• Link on the OSGeo Home page

• Can set you up with the following infrastructure

• OSGeo issue tracker

• OSGeo mailing list

• OSGeo svn

• http://downloads.osgeo.org


Other Projects
Play nice with others


Other Projects

• Some communication and collaboration is expected
(often around release or data QA issues)

• Example: PostGISrelease procedure checks functionality with
MapServer and GeoServer

• Example: MetaCRS project is a meeting place to discuss co-
ordinate reference system accuracy issues
(so the data is aligned correctly)


Other Foundation Activities


Committees
• The Foundation contains more committees, presently these
groups have not requested direct contact with software
projects.

• Public Geospatial Data Committee

• Education and Curriculum Committee

• Website Committee

• Conference Committee


Local Chapters

• Local Chapters have been set up all over the world, activities
range from talking shop at the pub, through to focused code
sprints or raising funds for the development of speciﬁc
features.


Thanks!
