Using RDF in XML documents

• Thread-topic: Using RDF in XML documents

I want to add document metadata, based on the Dublin Core, to a number of XML files. The initial proposal was to include a <DocumentProperties> element which would contain child elements similar to that shown below:
<Document>
	<DocumentProperties>
		<Title>RDF Test File</Title>
		<Created>2003-09-01</Created>
	</DocumentProperties>
	<Section>
		etc....

However, after scanning the web I came across numerous articles relating to RDF at which point I decided to add the document metadata using RDF statements, but I am unsure how to include this in the XML files. Do I just replace the <DocumentProperties> element with the <RDF> element as the first child of the root-element? i.e.
<Document>
	<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:dc="http://purl.org/dc/elements/1.0/">
	  <rdf:Description rdf:about="RDF Test File">
	    <dc:title> RDF Test File </dc:title>
	    <dc:creator> John Smith </dc:creator>
	    <dc:date> 2003-09-01 </dc:date>
	  </rdf:Description>
	</rdf:RDF>
	<Section>
	etc....

I assume I would then need to add the RDF vocabulary to my XML Schema in order for the XML file to be valid?

Finally, how does the RDF Schema fit in?

Thanks in advance
Harvey
