This fits in with other approaches to geographic information, and 
I suggest we all use the new maps-l mailing list for all of this.

1) More articles ought to have coordinates, in all languages of 
Wikipedia. Is this also relevant to Wiktionary, Wikisource, 
Wikinews, Wikiquote?

2) We need some quality assurance, to make sure we have the right 
coordinates for each place. Making it easier for normal users to 
verify and update coordinates would be helpful. Usability project?

3) Coordinates can now be specified in many different ways, but we 
ought to have fewer, more standardized ways (templates).

4) The output of the templates should be as useful as possible: 
 * link to the GeoHack page,
 * geo microformats,
 * <span class> markup that can be modified by personal CSS/Javascript,
 * in the future also inline maps from OpenStreetMap.

Could we write a specification for what a coordinate template 
should be able to handle?  Could someone write a history of how 
Wikipedia's coordinate templates have evolved over the years?

Håkon, did you only look at the English Wikipedia?  Different 
languages have different coordinate templates.  When I ask around, 
the Germans are convinced that their new template is the best, but 
they can't give a short summary of why this is so.
