hi ross,
apologies for the delay!
as long as both URIs represent a book title, i have no objections.
my comment was a rather generic warning - URNs and "non-URN URIs" can of
course be linked by owl:sameAs.
intelligence of a human or machine agent depends on the subtleness and
quality of that agent's category system. if everything is sameAs to lots
of other things, then the amount of intelligent conclusions you can draw
from the LOD cloud will be limited.

Martin,
Given that there's apparently considerable disagreement here (and
probably plenty of confusion), can you elaborate on what exactly you
object to in this request?
The first objection I saw raised was by Tom Morris ("is a FreeBase
topic really a book?") and agree that urn:isbn:9780670063260 is not
the same thing as http://rdf.freebase.com/ns/en.on_the_road.
However, I'm not sure I see that distinction between
urn:isbn:9780670063260 and
http://rdf.freebase.com/ns/soft.isbn.9780670063260.best as they're
both trying to identify an edition (or, loosely, a frbr:Manifestation)
of a work.
My questions would be:
1) If the latter relationship is not a good fit for owl:sameAs, why?
2) if #1 is true, what is a better alternative?
I understand the rationale of not wanting to water down the semantics
of owl:sameAs to the point that it's little more than rdfs:seeAlso
with louder voice. At the same time, it's difficult to see if your
issue is with a type mismatch between a URN and a URI; how FreeBase
models their data; or general "mutually assured destruction"-ness of
owl:sameAs.
Thanks,
-Ross.

dear all:
quite clearly, a book title is not the same as a book, and if the linked
data community continues to link apples and oranges via owl:sameAs then
either
- the socially agreed meaning owl:sameAs is being degraded to untyped href
in HTML
or
- vast amount of data in the linked data cloud turns useless
but as a minimum precaution against spoiling the graph of data, put your
sameAs statements into separate graphs so that meaningful applications can
filter them out easily.

But is the description of the book (ie Freebase topic) really the same

Assuming it was, wouldn't you not only have to make the sameAs
assertions and publish them someplace, but also get them loaded into
sameas.org <http://sameas.org>?

Ah hah!
Now how to (nicely) get that indexed...
Make a linkset and publish it via:
1. A data dump
2. SPARQL endpoint
3. Your Linked Data Space .
Then you have your index, and others can make their variants by meshing
their data with yours :-)
Re. DBpedia, we can add the linkset to its own Named Graph as we've done
with other linksets.
