But that's me making a reasonable guess and getting on with it.
The EPrints document is a URI which represents a conceptual document
which consists of a number of actual files, eg. HTML+JPG+CSS, so the
dct:hasPart makes sense there. The main issue is how to relate the
document to the metadata record, and you rapidly decend into FRBR hell.
Until a few people have consumed my data I consider it very much a work
in progress!

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> .

I was wondering if there is an existing predicate for linking to a PDF file?
I would like to incorporate a link between bibliographic reference description
and a URL to the location of a PDF of that document.
I had minted a predicate txn:hasPDFVersion, as demonstrated in this RDF snippet. (Part of http://lod.taxonconcept.org/ses/v6n7p.rdf )
<txn:SpeciesOriginalDescription
rdf:about="http://lod.taxonconcept.org/ses/v6n7p#OriginalDescription">

Some have suggested using rdfs:seeAlso to link to what could be a multimegabyte
PDF, but I think this would cause problems for a number of RDF crawlers like
Elmo.
In summary, I think it would be useful to have a predicate that can be used for
linking specifically to a PDF document.
Is there an existing predicate for this?
What do people think about the suggestion to use rdfs:seeAlso to link to a PDF?
I would also like to know of others thoughts or suggestions regarding this
issue,
Respectfully,
- Pete
