[tdwg-content] Fwd: Is it best practices to use a rdfs:seeAlso link to a potentially multimegabyte PDF?, existing predicate for linking to PDF?

[Peter DeVries]

I thought that I would run the PDF question past the some lod experts.

Here is the first reply

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 <
