Regarding attribution, commonly it is assumed that you have to respect
it transitively. That is one of the reasons a license that requires BY
sucks so hard for data: unlike with text, the attribution requirements
grow very quickly. It is the same as with modified images and
collages: it is not sufficient to attribute the last author, but all
contributors have to be attributed.
If we want our data to be trustable, then we need traceability. That is
reporting this chain of sources as extensively as possible, whatever the
license require or not as attribution. CC-0 allow to break this
traceability, which make an aweful license to whoever is concerned with
obtaining reliable data.
This is why I think that whoever wants to be part of a large
federation of data on the web, should publish under CC0.
As long as one aim at making a federation of untrustable data banks,
that's perfect. ;)
