maybe e-mail identyfication? authors ranking?
catpaw, do you mean kind of policy which will permit or not things to do with maps?
A license that allows, a) at least an infinite non-exclusive permission for the mapserver to host this thing (this should be a no-brainer). b) An allowness for anybody to download it, and use it on his server and also redistribute it. c) And an allowness to make modifications(improvements) and to be able to give it to others.
I don't think there have to be big controls, just like in wikipedia, they tell you all you content you enter there gets under their open license. If someone else tries to give what he doesn't own (which he cannot), you just delete it, if the real author(s) complains to you.
cc-by-nc-sa http://creativecommons.org/licenses/by-nc-sa/3.0/ would do okay i guess.
