We have a fairly complex system that will have a lot of maps, and a lot of non-techie map-editors. The maps need to be stored on our "commons" and displayed on multiple wikis, so we have ended up using .map files. They show up nicely on the various wikis, and we are happy going to our personal commons wiki to do the editing. But it seems that the only editor to change those .map files is the text editor. We have a programmer, and are interested in looking at the concept of perhaps modifying the GeoJson editor such that it can modify .map files too. Is there someone who can talk us through what all this would entail, how to get started, and the like?

There is a gadget on the French wikipedia that provides a geojson editor. Its called KartoEditor
