Developer community

A motley crew of OSM developers - having a break from coding!

There is an active developer community working on the various aspects of OpenStreetMap development. The project involves many separate components, and a diverse range of programming languages (and spoken languages!).

We have thousands of users all keen for the site to get better - and, like any open source project, not enough committed developers. So you can make a real difference. But the best way to make a difference is by writing and committing code - not by saying "what you're doing is wrong, I think you should do it this way".

Getting involved

  • Absolutely essential - read the mailing list. Major decisions are discussed there - not on this wiki, not on the OSM forum.
  • Learn who to approach for what. The wiki pages about particular projects or servers will tell you who maintains/administers them, or you can ask on the mailing list.
  • Be friendly.

Don't be an "Architecture Astronaut"

  • We all know the database/x/y/z isn't perfect. Really.
  • We would like your help.
  • Telling us how to solve the problem does not help. We probably already know.
  • Solving the problem does help.
  • You may have extensive reasons for not solving the problem. That's fine, but that doesn't help.

If you don't understand the above, please watch this video: How Open Source Projects Survive Poisonous People (And You Can Too) Or try this list debate about Parkinsons Law:

If you still don't understand, that's fine, but we should now part ways. The best way to help openstreetmap's technical base, as a coder, is do some actual coding.

FIXME need some links to past endless mailing list debates about some of the key issues.
