HyperText Topology in RDF

I was reading about the topology of HyperText links, and wondered if links
wouldn't be better expressed in RDF? For example, I could create some ns
denoting that a resource has a link, and then use an rdf:Description to
describle the topology of that link.

Example:-

<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
      xmlns:dc="http://purl.org/DC/elements/1.1/"
      xmlns:link="http://linkns.com/"
      xmlns:xlink="http://www.w3.org/1999/xlink">
 <rdf:Description rdf:about="http://www.w3.org/">
   <link:linkBag>
     <rdf:Description rdf:ID="link1"
         xlink:href="http://www.w3.org/MarkUp/"
         dc:title="HTML Homepage"
         dc:author="Dave Raggett et al."/>
   </link:linkBag>
 </rdf:Description>
</rdf:RDF>

Although that is a highly simplistic model (only describing one link
briefly!) you can see how by using RDF M&S it would be easy to define link
relationships between an entire module part of a site. In other words,
HyperText are nodes and arcs, so why not use RDF to describe them? You
could use some attribute of xlink to show how your certain link is
described in RDF. Notice that dc:author here implies that Dave Raggett
created the link rather than the href.
This is basically so I can get my XHTML to RDF deeley working: at the
moment it doesn't express link types very well (it gets the triples the
wrong way round, and uses rss:link). IOW: help, please! Is expressing XHTML
link semantics in RDF a good idea or not?
