Dublin Core was created to support keys like "Title", "Description" and 13 
other "very exciting" keys (RFC2413) -- there must be a reason... 
Keynames are constants. Adding "dc:date" instead of "creation date" should 
make no difference in space and processing. Don't drop the prefix. 
Processing is much easier then. Anyway, most apps will simply call the 
"direct" methods below, so there is no overhead.
