[OSM-legal-talk] What extra permissions are needed to include CC-BY data in OSM

Apologies for the delay in my response.

Not from their general inquiry address; I've put another line in via a
shared contact.

I've been meaning to ask if you could clarify a bit further, and/or correct
my understanding of the situation.

3(a) also includes subsections 2, 3 and 4. My message discussed 2; 3 and 4
reads as follows:

If requested by the Licensor, You must remove any of the information

"the extent reasonably practicable" sounds to me like it could be satisfied
by editing http://wiki.openstreetmap.org/wiki/Contributors.

3(a)(4) is a pass-through of the attribution requirement, but the
flexibility afforded in 3(a)(2) means that OSM's current practices should
accommodate it.

Nope. I was referring to collective databases in the ODbL which are

This is the part I think I could use help understanding. My impression is
that a collective database can contain ODbL and non-ODbL content
side-by-side. Are you saying that CC-BY 4.0 makes this impossible because
its attribution requirements would attach to the non-ODbL content as well?
