Dated June 2010... It appears someone raced me!
I look forward to seeing this implemented.
Only... One weakness in the existing document that might be addressed
as an "upgrade" to this specification at a later date: there appears
to be scant reference to methods of specifying date and time as part
of GEO hyperlinks. For some GIS applications, this might be important.
(I grant that this could be a nightmare to implement on geological
time-scales where it's hard to decide upon a fixed longitudinal
reference point, but on shorter time-scales of hundreds or even
thousands of years, this feature might be a boon to the publication of
historical maps and data.)
What say you? How might I suggest this to the relevant people, if not here?

Hyperlinks for geographic coordinates are a mess. Designers of web
applications are being forced to design their own solutions to make
geographic links more user-friendly...

There's a relatively simple solution to all of this that could easily be
upgraded over time. We already have "mailto:"; hyperlinks, for example, that
accept certain fields and map those to certain parameters within a
user-definable (or system-specific) mail client application.
The same could be done for geographic data. The user might install certain
geographic information systems on their viewing device, specify their
favourite for "geo:" links, and then when they follow a hyperlink with
geographic content, any relevant information fields present might be
transferred over to the geographic information system (GIS) as coordinates.
I suggest for the HTML standards people to simply talk to Wikipedia or
Google and copy their system, as a starting-point for discussion at least.
Maybe their format could be tidied up slightly, but generally I think
they've done a good job and that their work should be adopted as a standard,
so that you don't end up seeing pages with dozens of hyperlinks (one for
each GIS) as we do on Wikipedia.
