RDF for MP3, ASF, etc.

I was just wondering if someone could help me understand how RDF will work
anything other than text-based files, e.g. html, xml, svg, etc., etc.?  For
instance, I completely understand how an agent could find the metadata in a
document like this:
 
<html>
<head>
  <rdf:RDF
    xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
    xmlns:dc="http://purl.org/metadata/dublin_core#"> 
    <rdf:Description about=""> 
      <dc:Creator>
<rdf:Seq ID="CreatorsAlphabeticalBySurname"
  rdf:_1="Mary Andrew"
  rdf:_2="Jacky Crystal"/>
      </dc:Creator>
    </rdf:Description> 
  </rdf:RDF>
</head>
<body>
<P>This is a fine document.</P>
</body>
</html>

... however, what if the document is an MP3, ASF, or even a Word Document
for that matter?  How would I -- surround?? -- my file with the RDF syntax?
Are we going to have to rely on middleware packages to provide this
functionality, or is there a more reasonable, i.e. cheaper and easier, way
to do this?
 
Thanks in advance, if anyone can answer this for me.
 
Kind regards,
