Authoritative examples of DC element usage?

["wkearney99" <wkearney99@hotmail.com>]

Hi all,

Is there someplace that discusses what's appropriate for the contents of
various Dublic Core elements?

I'm specfically interested in dc:publisher and dc:creator but other fields
are also of concern.

What's really supposed to be in these?  The specs are ambiguous at best.

My specific question is where should an e-mail address of the publisher,
creator, contributor and like persons be placed and using what format?
