There is a slot for that in the Commons {{map}} description template
http://commons.wikimedia.org/wiki/Template:Map
using the field "projection",
with a handful of values that have internationalisations defined at
http://commons.wikimedia.org/wiki/Template:I18n/map_projection
But it's not clear whether/how the template should store relevant
parameters.
I'm not sure whether the information can be used as a baseline by
MapWarper yet. (Tim ?). Or whether there are good scripts available to
estimate a projection, given georeferencing points.

If we are going to go through the trouble of storing geo-referencing data, we
would be silly not to add original projection type when known. There are a few

from which there is script that an admin can use to add the data to the
map-warper.
This doesn't capture all of the data stored by Klokan Georeferencer -- eg the
useful information as to what layer the image was georeferenced against -- but
is enough to get the geo-referencing data into the system, and to then get it
out in various formats, including serving georeferenced tiles.
Sorry if it's all still a little bit round-the-houses; but with luck everything
should get a bit more streamlined, as we get more geared up for large scale
import.
(There are already a couple of thousand images on Commons with links to
external georeferencing, either at NYPL or the British Library; plus ready to
be uploaded to Commons a further 6,000 georeferenced map images from the BL
Mechanical Curator collection, just as soon as I've got auto-categorisation a
bit more worked out, with that number currently increasing by approximately a
further 100 georeferenced images a day
https://commons.wikimedia.org/wiki/Commons:British_Library/Mechanical_Curator_collection/georeferencing_done
).
As far as I know, nobody has yet actually used the script to import
pre-existing georeferencing onto the warper.wmflabs.org server, so I'm quite
interested to see how you get on!
Best regards,
James.
