Yes.

I meant section 2.1 of the current DbCL, I'm sorry for being unclear.

I hadn't considered that before but that makes sense, yes.

Ah OK. I was assuming the Produced Work would be the image/map tile/etc. 
. To be clear: the Produced Work is a representation of a subset of data 
from the database in some kind of result set format?

No, all this context is really helpful. :-)

> The really simple answer IMO is that Clause 8e addresses "the entire agreement" ONLY between the parties to that agreement, which in the case outlined above is the "mojo creator", who is the Licensor of their CC content under the CC-BY-SA license and not the ODbL licensor, who can be someone completely different and isn't a party to this agreement. It's the "mojo" that's licensed.

The mojo creator is the "You" of the ODbL, and the BY-SA downstream user 
is not the "You" of the ODbL.

Yes I think I remember that.

Thanks!
