The ODbL does incorporate attribution. From a given work you can find 
out which dataset was used to produce it, and from a given dataset you 
can find out who produced it.

BY-SA already requires less attribution than the GNU FDL, and this was 
an issue for some people when Wikipedia was relicenced -
