The reason we used DC Contributor instead of Creator is because the semantics 
do not map well to MARC creators/contributors. Creators in MARC can be in 1XX 
and 7XX; since 1XX is not repeatable, additional creators go in 7XX. 
Contributors in Dublin Core play a secondary role in the resource ("An entity 
responsible for making contributions to the resource.") vs. Creator ("An entity 
primarily responsible for making the resource.").If we simply mapped the name 
in 1XX to Creator and the name in 7XX to Contributor, these may or may not be 
correct in terms of semantics. In MARC primary vs. secondary contributions are 
not what distinguish recording in 1XX vs 7XX, but the particular contribution 
that was made may be included in the role subfield ($e in textual form or $4 in 
coded form). Unfortunately we find that many MARC records do not record the 
role, but that is because of previous cataloging policy, not anything in MARC.  
 Another point is that whether the contribution is primar!
 y or secondary may vary depending on the type of material, so giving the 
specific contribution may be more useful in the long run (for instance, an 
illustrator may be considered a secondary contribution in the book world, but 
if the resource is in a museum it may be considered the primary contribution).  

It might be noted that some time ago (the year that the DC conference was in 
Florence, I can't remember exactly when that was) the Dublin Core Usage Board 
(of which I was then a member) attempted to combine creator and contributor 
(and publisher) to become one DC element (Agent), but implementers objected to 
it, so the proposal was withdrawn. But that was recognition that the 
distinction being made might not have been the best way to go. That was also a 
factor in mapping MARC to DC this way.

It looks like it's using Contributor instead.  So I'm guessing the sticking 
point is that it's hard to figure out what Contributors are primary, so it's 
safer to just punt and put them all in Contributor instead.
