Reconciliation between CC and ODC

First of all, OSM is not merely "raw map data". It is not "nothing more than a set of facts". OSM is the source code for a map, which, when combined with a stylesheet (e.g. http://trac.openstreetmap.org/browser/applications/render...) and a compiler (e.g. Mapnik), produces a map.

Secondly, "a set of facts" *is* copyrightable, if there is selection or arrangement of those facts. OSM is a selected, organized, cross-linked set of facts expressed in a non-human language.

If you are going to claim that OSM is "*nothing more* than a set of facts", then you should be able to provide a simple and obvious explanation of what category of facts OSM covers. For instance, the white pages is "a listing of the name, address, and phone number of every person in a certain geographic area".

What is OSM? "A listing of all geographic facts about the world"? Certainly not. What is it? What is the *idea*, which you are saying can be merged with the *expression*.
