Well if you distribute the result as a database then that is a
derived database and you need to license it on the same terms
as I read things.

The wiki also implies that OSMF intends to ask for a Mozilla style
clause to make you actually offer the data back to us - at least
that is what I think it is saying. I'm not at all sure that is a
good idea though.

The wiki also says that a cartographer producing maps would need
to give their data back, but I don't see that in the license unless
they ship that map as a database rather than as a rendering. Especially
as the wiki then implies that "artistic cartography" doesn't have to
be contributed back.

I believe so, yes. A shapefile would be a derived database and hence
would have to be licensed on the same terms I believe.

Clearly that is distribution of the database so 4.6(b) would require
you to make an unrestricted version available.
