Certainly. the tabulator follows rdfs:seeAlso and expects some terse RDF. and so would be crippled by any large file, and PDF would not of course help it at all. I take seeAlso as a fairly strong request to see the other thing, like an HTTP redirect. Not a generic "this is vaguely related" link at all, and not in general to point to human-readable stuff.
