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

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!
