Re: PROPOSED RESOLUTION: use dcterms for the maker element and rename to creator

All valid points Andrea.

I'm not sure how strictly property ranges are ever actually enforced. 
There are plenty of instances of <dc:creator 
rdf:resource="http://...foaf.rdf#me" on the Web and the range of 
dc:creator is string. Actually, I believe it is this fact, that emerged 
at the 2005 DC conference that I had the pleasure of attending, that was 
one of the drivers for the change to dcterms:creator.

In other words, my guess is that we may well see quite a few 
dcterms:creator elements pointing to a foaf:Organization class... and 
UAs may or may not notice.
