Hi,
i don't think that attribution match with osi definition, as it requires  to allow derivative works, and CC-by has not this clause. 
I do agree that CC-by-sa match with osi definition as this second license allows derivative works.
Despite of this, remember that in some legal sistems the attribution clause is not required, as the law requires this kind of right. So for instance in cc-spa and in cc-ita they have decided to include the attribution clause per defoult in all the license solutions.

A question: about the source code: as CC refers to multimedia many times there is not source code. But, in CC there is not requirements to deliver or make availabe a copy of the work in an open format (as FDL does). Any comments?
