 As you already found, the ICMFDublinCore should be supported by both,

 Except for the fact that no CMF (or AT) content type uses the
 zope.dublincore variant? ICMFDublinCore is also much more than I'm
 interested in - IDCTimes is all I need.

I see that IDCTimes provides the created and modified schema  
attributes. CMFDefault's DublinCore has created and modified  
methods that return the same thing, DateTime instances. If you wanted  
to force the ICMFDublinCore semantics into the CMF it looks like you  
would have to change a ton of code that expects those two to be a  
method. Is that really worth it?

 Are there any objections to making the CMFCore interfaces derived
 classes from zope.dublincore, or possibly even using those directly
 where possible?

Do you see any specific benefit, more than just replace our code with  
other code to shift the maintenance burden?

- -0 unless we come up with convincing evidence that the Z3 version is
actually being maintained by somebody who cares about it:  Actually,
after looking at it, -1 unless it is getting some love *and* we can
avoid entangling ourselves with its policy-laden configure.zcml.

The zope.dublincore code hasn't seen any maintenance since being  
exploded out into a separate egg, this is true. In all fairness, the  
DublinCore module in CMFDefault hasn't seen many changes that are  
specifically Dublin Core-related, either, but then again it hasn't  
needed much. It's been working very well with very little maintenance.  
Don't fix it if it ain't broke and keep what we have is what I'd say  
here.

I found myself writing some code which needs to get dublin core data from
content and should work for both zope3 and zope2 applications, except
for the difference in interfaces.
