Hi Dave,

I respectfully disagree.  Here is a quote from the document "Using 
Dublin Core" at 
http://www.dublincore.org/documents/2001/04/12/usageguide/.

In this guide, we have chosen to represent Dublin Core examples in several 
different syntaxes, including: HTML ( the Web's Hypertext Markup Language 
format), RDF/XML (the Resource Description Framework using eXtensable Markup 
Language) and in a generic form (Element="value").  ...  When considering an 
appropriate syntax, it is important to note that Dublin Core concepts are 
equally applicable to virtually any file format, as long as the metadata is 
in a form suitable for interpretation both by search engines and by human 
beings.

Your email seems to contend that Dublin Core has some special "tie" to
RDF.  By "ties" I do not mean influence or contribution, I mean dependence
and exclusivity.  So, what is the dependence of DC on RDF?  
More below...

Really? How has DC effected the design of RDF?  It is not like the DC 
elements are earth shattering.
Just a nice standard set of definitions.  Also, considering I can just as 
easily use the same elements in HTML or XML, what is the benefit of 
using them in RDF?  I would like to see a concrete example that delivers
clear value added.

It is obvious that the DC elements can be RDF predicates about Resources.
But you still have not proven that they are *more useful* in RDF than 
in XML.  That is the key issue.
