RDF Hyper-linking - slide "Extensions"

We can do a lot with just rdfs:seeAlso, but RDF allows more. We can give the type of the things rdfs:seeAlso relates:

<Person>
 <name>Dan Brickley</name>
 <rdfs:seeAlso>
   <x:Bibliography rdf:about="../stuffIwrote.rdf"/>
 </rdfs:seeAlso>
 <rdfs:seeAlso>
   <x:Resume rdf:about="../cv.rdf"/>
 </rdfs:seeAlso>
</Person>

This helps RDF crawlers be more discriminating, eg. by only traversing links to bibliographies or other people, not bothering with CVs.
