What is the point in paragraph 4.3, if it can be easily side stepped? 
And would the large data set import rights holders be happy if they 
found out? If this paragraph is only for show, I suggest it is removed 
for brevity and clarity.

I agree, they are evil. My concern is ODbL wants to have its cake (to 
have attribution) and to eat it (to allow public domain produced works), 
which is a contradiction. Since I agree with your interpretation above, 
I say we drop the attribution requirement completely, for produced works.

That seems a bit of a sweeping statement, as far as I understand? Surely 
our CC-BY-SA license is compatible with CC-BY-SA and CC-BY imports, 
since the attributions are carried forward? (Although, as Richard 
pointed out, this is also quite complicated. 
) This really only becomes an issue if/when ODbL relicensing kicks in, 
as I understand.

This issue also applies to OS opendata, as it requires attribution. Is 
work afoot to get OS to agree to compatibility with ODbL? (Probably in 
the LWG?)
