Hugh Glaser's sameAs.org site [1] provides a facility for finding
multiple URIs for the same concept. How about a site which does the
opposite: indicates where URIs refer to _different_ concepts? Obviously,
this is only helpful where you might be tempted to assume that the
concepts are identical, e.g. because the same word or phrase is used to
describe/identify both.
Wikipedia's disambiguation pages are doing this job for human readers:
is there a Linked Data equivalent?
I've experimented with this in my FOAF file: basically I provided descriptions
of other people with the same or similar names as me (homepages etc, whatever I
know about them, preferably IFPs) and then declared them to be
owl:differentFrom me. In the end I removed it again because I like to keep this
a bit fuzzy for privacy reasons. ;-)
Other use cases... hmmm. Maybe product descriptions where you have lots of
slightly different versions of a product that might get confused.
I definitely think it's useful for Linked Data purposes, just like owl:sameAs,
IFPs and everything that Allemand and Hendler describe as RDFS-Plus (although
they don't include owl:differentFrom in that).
