FYI, I have just commited a preliminary version of a GEO mode (location
management, if you will) to CVS HEAD. You will have to set
"$wgUseGeoMode = true ;" in LocalSettings for that to work.
Currently, it does not do *that* much: It uses the ISBN mechanism, but
with the GEO keyword, like "GEO 1.22.33:-4.55.66". This is converted to
a link to a "SpecialGeo" page, which currently only shows a link to the
according MapQuest page.
As a special option, I hard-coded a regular expression
search-and-replace that will work on the RamBot articles (like
"38°30'10" North, 90°38'42" West");
coordinates on these pages
will thus be linked likewise.
At the moment, it does *not* store the coordinates/article data pair in
a special database table, which will be required for "real" functions,
like "what's near this location". I might implement that later, unless
someone beats me to it (hint! :-)
