Re: Is it best practices to use a rdfs:seeAlso link to a potentially multimegabyte PDF?, existing predicate for linking to PDF?

I see that Chris Gutteridge uses dc:hasPart for the ePrints RDF (eprints.org).
Eg:

<http://eprints.ecs.soton.ac.uk/21681/>
	dc:format "text/html";
	dc:title "HTML Summary of #21681 Consuming multiple linked data sources: Challenges and Experiences";
	foaf:primaryTopic <http://eprints.ecs.soton.ac.uk/id/eprint/21681> .
...
<http://eprints.ecs.soton.ac.uk/id/eprint/21681>
	ep:hasDocument <http://eprints.ecs.soton.ac.uk/id/document/36430>,
...
<http://eprints.ecs.soton.ac.uk/id/document/36430>
	dct:hasPart <http://eprints.ecs.soton.ac.uk/21681/1/cold2010%2Dpaper16%2Dcamera%2Dready.pdf>;
...
