The fun! project of getting OpenStreetMap maps deployed on Wikimedia
servers (e.g. Wikipedia) is grinding forward at a healthy pace. For those who have no idea what it is you can read the original announcement on the Wikimedia techblog.

Unfortunately the project has been somewhat delayed by the
Wikimedia.de servers mentioned in that posting taking a bit longer to
arrive than expected (the DB server is still not up).

I've personally had some much needed time to work on it recently,
right now I'm hacking static map generation as outlined in this RFC.

(see also this posting on wikitech-l)

If you'd like to help here's the bug list I'm working on.

There are lots of tasks to be done. One very interesting task that I'm
sure someone would be happy to work on is seeing how this setup scales
to >200 languages or so.

Ideally Wikimedia will have static map generation / a tileserver
that'll render maps in the locale of the target wiki, so it'll e.g.
use name:de tags for de.wikipedia.org.
