There is no 1:1 problem as long as we are clear what is being described. I
completely agree with your analysis above, but that doesn't make it any
less true that both Carl and yourself are dc:contributors to the overall
document (or Web page or whatever you want to call it) that is the
combination of the text/html and the image/png (i.e. the Web page that
appears in my browser and that I print on my printer).
Carl is the illustratorCreator of the image and an illustratorContributor
of the document. There are two separate properties and therefore have to
be given two separate names if we want to make these kinds of
distinctions.
However, my feeling is that DC doesn't need to make the distinction
between these two things. I'm reasonably happy to accept that
'illustrator' is a useful property for resource discovery, but it is the
'contributor' kind of 'illustrator' that is most useful, not the 'creator'
kind of 'illustrator' (because if I'm looking for an image created by a
particular illustrator, I can already do that by looking for images with a
particular dc:creator).
