I was thinking about creating a type of output in the special page that
pruned the graph so that the only nodes and edges left were related to
locations. For example, it would prune all nodes not having a geo attribut=
e
and all relations not {located in, is located in}, etc. We would love to b=

able to better support location-based services on campus and a good way to
do this is to provide a very simple XML document that contains just the
basic location info.
In principle, it would also be possible to extract a similar graph from the

I agree that RDF output would be useful. This is logically the next step
for the extension. I'll add it to my to-do list.
The Python Geo-API is also cool. Denny, our main Python hacker, is also

Have a look at http://wiki.case.edu/Olin_Building, its history, and its tal=
k
page. It appears that links to Google Maps and Mapquest for locations in
the NW quadrant of the globe aren't formatted properly. The link to the
MapSources page works great.
Also, we have been using the GIS extension since the wiki was started. I
would love to convert to SMW, but the following are holding us up:
1) Users must type the degree symbol to input coordinates. Not everybody
can do this. Ideally, they should be able to copy and paste from the old
extension (ex <geo>41 30 17.33 N 81 36 29.58 W</geo>).
2) We would like to define our own links to be displayed next to the
coordinates in the fact box. Ideally, we don't modify the source to do
this. Could the list of links be converted to a setting or MediaWiki
message somehow? If using a MediaWiki message, it is possible to pass
parameters to the message to control what exactly is displayed. If nothing
at all, can we at least easily change the MapSources URL via a system
message?
