There has been rapid progress on the subject of adding OpenStreetMap
maps to Wikimedia projects (e.g. Wikipedia) during the MediaWiki
Developer Meet-Up taking place right now in Berlin.
We now have a clear plan of action for getting OpenStreetMap maps
embedded in Wikimedia wiki (e.g. Wikipedia) pages:
* Wikimedia will set up a database to mirror the OSM data (Planet.osm)
* Wikimedia will set up its own rendering infrastructure for rendering
tiles & other maps from the OSM data
* The existing MediaWiki extensions for displaying OSM data in a
MediaWiki article will be improved to work acceptably in production on
To prototype all this we'll be using new infrastructure provided by
Wikimedia Deutschland. Once things have been tested there they'll
eventually be deployed on the main Wikimedia sites.
After discussion with the Wikimedia operations people (including Brion
Vibber, Mark Bergsma et al) there seem to be no objections to the
above plan as long as:
* The tools involved are improved to be relatively stable & deployable
on Wikimedia, e.g. being able to embed more than one slippy map, the
internationalization of error messages etc.
* The end product (the generated tiles or map files) are cachable so
that they can be thrown at the frontend squids, as they're static
images this should be easy.
The featureset that we're aiming for to be able to deploy this on
Wikimedia sites from the view of the user (more can be added later
once we've got it working) is:
* The ability to embed OSM maps in articles with something like the
Simple image extension, perhaps automagically turning into a Slippy
Map if the browser supports it
* A static or slippy map that can be used by geotagged articles so
we can have maps without explicit inclusion of a <map> tag.
We'll also set up a map toolserver for experimenting with other uses
of OpenStreetMap data on Wikimedia. People with relevant projects can
get access to this toolserver to try out their ideas for tools that
could eventually be integrated on the main Wikimedia sites.
This project is seeking help from anyone who's interested who'd like
to be a part of making this happen, if you want to be a part of adding
