Completely agree. I'm very happy with the direction of DC terms. The 
foaf:maker property was essential for a while, until DC was cleaned up. 
I'll mark it as a sub-property of dcterms:creator. I hope we'll get 
reciprocal claims into the Dublin Core RDF files some day too...

Copying Tom Baker here. Tom - what would the best process be for adding 
in mapping claims to the DC Terms RDF? Maybe we could draft some RDF, 
put it onto dublincore.org elsewhere, and for now add a seeAlso from the 
namespace RDF?
