I agree, it's bending the terminology a lot. It wasn't me who came up 
with the 'str' and 'int' example.

Well, imagine

   >>> str(123)
   '123'

Here '123' is the 'str' adapter of the integer 123. It's conceptually 
the same if you do

   >>> IZopeDublinCore(myobj)

except that in the str(123) case, you call the class directly instead of 
using the Component Architecture's registry as a flexible dispatch.
