We are here to help and we are not alone!




Are you Lonely

6

•OSGeo Foundation offers

• 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

7




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?

8




Are you broke?

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...

13




The BadgeSeeing beyond Branding

14




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

• It is actually open source!

• There is documentation

•Open to your involvement and participation

• Code ownership has been checked(so it is unlikely to be pulled suddenly)

• Project has a measure of legal protection(unlikely to be pushed under)

15




Project Benefits• “Community” - join your map making peers!

•Marketting: OSGeo badge / branding / OSGeo Live DVD

• Infrastructure: hosting, mailing lists, version control, etc..

• Collaboration: Education, Open Data, Standards, Code Sprint

•Other: Shelter, Communication, Outreach

• Tip: OSGeo Foundation has a mandate to promote open source spatial (even before your project joins)

16




Foundation Benefits

•Mandate - to promote open source spatial

• Additional capabilities for open source mapping

• Additional prior art (safety in numbers)

• Communication

• Projects provide an “officer” as contact person

• Project name, branding, license, details are quickly available

Incubation Checklist

49




OpenProject has open, active and healthy

user and developer community

50




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

51



http://opensource.org/

http://opensource.org/


Community• Active

• Community of users and developers

• Support each other

• Example: Collaboration during release

• Healthy

• Long term viability

• Participation from range of developers / organisations

52




Copyright and LicenseCheck a project has obtained the ability to release

53




• Source code available under an open source license

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

Source Code License

54




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

55




Sanity Check

•We ask for a Provenance Review

• Check source code

• Check documentation

• Check data

•Do you know who gave it to you?

56




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

57




ProcessVersion control, issue tracker, decisions

58




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”)

59




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)

60




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)

61




DocumentationDon’t be scared, looking for a basic quickstart

(and enough for a volunteer to help out)

62




User Documentation

• Basic Quickstart

• Guide new user through performing “core functionality”

• That was not so bad was it?

63




Developer Documentation

• Checkout and build instructions

• Code documentation

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

• Comments!

64




Documentation Questions

•Q: How to submit a patch or fix?

•Q: How to contribute a new feature?

65




ReleaseReal artists ship

66




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

67




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”

68




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?

73




OSGeo Board

• 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

74




Marketting CommitteeVolunteers from all over the world

75




Marketting Committee• 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...)

76




System Admin CommitteeInfrastructure help if you need it

77




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.org78




Other ProjectsPlay nice with others

79




Other Projects

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

• Example: PostGIS release 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)

80




Other Foundation Activities

81




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

82




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.
