Not quite. The differences I can see for the CIA Factbook entry
(examples I sent
earlier, happens to be the first entry in the catalog.rdf.bz2 that I
have lying around)
* Different subject URI <-- very important, could kludge with
shouldn't have to
* Different layout for dc:subject (uses a rdf:Bag in one, a simple bunch of
bnodes in the other)
* Creator/Contributor/Publisher has a URI in the individual files but a
in the catalog.rdf.gz. Using a URI is the right way to do it.
* Links to downloadable resources are absent in the catalog
So the first means that it is ambiguous which thing I am referring to if
I use your
URIs without going to the trouble of putting in owl:sameAs and then
on that (resource intensive and messy).
The second means that when I create a lens (c.f. fresnel vocabulary) for
at the data I can't do it in a consistent way because sometimes
one shape and sometimes another.
The third means that if I want to present all works by an author I have
to smooshing on a text string when you already have URIs minted for that
The fourth means that I can't provide links to the actual text, or
automatically for indexing/text-mining purposes if I use catalog.rdf.bz2
The information is *similar* but not the same.
