Re: Wine Ontology

Thanks for catching that Charles.  I suspect it was generated by an emacs 
macro that was scraping the winery definitions.  There are actually a 
bunch of duplicated ones there and in other allDifferent statements.

It is perfectly legal OWL from a syntactic standpoint, but semantically it 
should generate an inconsistency since an individual can not be different 
from itself.

I've updated it in the version of wine.owl that I'm working on.  I'll post 
it in a few days.

All,

I was reviewing the wine ontology and had questions about a couple things. 
(Other than the winery named McGuinesso which seems to have been named 
after a certain person at Stanford University and Congress Springs Winery 
which is now named Savannah-Chanelle.) The other somewhat more relevant 
issue is that at the end of the ontology is a list of <owl:AllDifferent> 
which contains the following:
      <vin:Winery rdf:about="#Marietta" />
      <vin:Winery rdf:about="#Marietta" />
      <vin:Winery rdf:about="#Marietta" />
      <vin:Winery rdf:about="#Marietta" />
along with a bunch of other names, many of them repeated. Is that valid 
OWL? Seems odd in that it logically it would be saying that a class is 
different than itself.
