GPL, LGPL and BSD licenses are for software, not necessarily
appropriate for geodata.

My big concern is how you define derived work. Immanuel, since you're
so adamant, please take a stab at the following scenarios: (and anyone
else that feels strongly about it)

If I buy a license to the government's census data, can I make a map
with that data and OSM's? What's the status of my work?

Can I use the data in a proprietary mapping application if I make the
data I add publicly available, or do I also have to open up my

Can I just create a map with OSM data, but keep rights over my
artistic rendition?

If I add information to the OSM data and overlay it with my points of
interest database, what do I have to contribute back? The map, the
POIs, or just what I added to my OSM data set? (The POIs do not seem
consistent with the rest of the data structure in OSM)

Whatever license we end up with, derived work has to be nailed down. I
believe nothing will hamper adoption more than uncertainty over that
