If I remember correctly the original post that started this of Ben
has
it about right. We need some tags which say "these two database
records
are about the same protein, well, sort of, at least in this case, for
the purposes of what I am doing".
I agree - the issue also came up at the BioHackathon last week...
basically, as Tom Oinn phrased it, "if you're thinking of using
owl:sameAs... don't!"
Another predicate is needed that is less "rigourous" -
owl:kindOfLike :-)
I think there is another, potentially more nefarious concern in the
statement that Ben was objecting to in his post. The statement was:
http://www.uniprot.org/tissues/229 (subject)
http://www.w3.org/2002/07/owl#sameAs (predicate)
http://purl.uniprot.org/po/0009009 (object)
my concern is whether http://purl.uniprot.org/po/0009009 is intended
to be a class, or intended to be an instance... since owl:sameAs is
only supposed to be used to claim the "identicalness" of two
individuals, not an individual to a class...
Oh what a tangled "Web" we weave! ;-)
Well, if you can tell us how to do some weaving, we maybe can make
progress. The properties of sameAs are fairly easy to list. It is
transitive, reflexive, symmetric and substitutive: if A sameAs B and
something is true of A, then its also true of B. So, which of these
_aren't_ correct for the application you have in mind? Can you say why
not (an example will do)? "Less rigorous" doesn't cut it.
