For every globe we would always need a geodesic system. Even if it is the Mars, we need to know where are the poles, where is the 0 Meridian, etc. Refering to these seems to make most sense.
Which does not mean that we should let the user decide if they want WGS84 or Ares Prime 0, or Selenographic system etc. -- the editor should merely choose "Earth", "Mars", or "Moon" respectively. (Names are made up, I could actually not figure out what the usual geodesic systems are).

Hey,
Why use Q2 ("earth") as the glob, and not Q215848 ("WSG84")? That would be a lot clearer, I think.
Since WGS84 implies Earth, this works for Earth. Is such an implication always present though? What if I want to describe a location on some random planet - I suspect you'd have to specify some system and the globe. If this is the case, we should not omit the globe.
Cheers
