Does DC have to reference RDF

I am new to the listserv and realize the following questions may have already been asked previously.  My apologies if they have.  I searched the Archive for the listserv and found related questions but I am still puzzled.

Since Dublin Core is a metadata standard that promotes a clear description of a resource, can it not stand alone?  If someone were writing an XML application that used DC as the metadata scheme could they not just reference the DC namespace alone?  When would you want to reference the RDF namespace?  I understand that RDF promotes interoperability but doesn't DC do that inherently on its own?  The DC website explains exactly what is meant by 'title' or 'creator' or 'subject' etc.  What is the added value of referencing RDF or writing RDF XML?

Regards,

Denise
