Luna Brainstorming
Andy Mabbett
Proposal
I propose a "luna" microformat, for marking up co-ordinates on our Moon. This would be based on the "geo" microformat (and thus relatively easy to implement, since code for "geo" can be re-used).
Note, though, that [1] and [2] indicate that more than one system of recording the co-ordinates, for any given point, is in use, and it may be necessary to include an attribute to indicate which system is to be used, though the most recent standards appears to be the IAU Mean Earth Polar Axis co-ordinate system, as used by NASA and [ttp://en.wikipedia.org/wiki/Apollo_11 Wikipedia], and described in Davies and Colvin, J. Geophys. Res., v. 105, pp. 20,227 - 20,280, 2000.
