[Pellet-users] [Fwd: example BnodeQueryExample error]

[Evren Sirin]

Note that, these are just warnings printed and not error messages. The 
problem is the ontology uses a property from OWL namespace 
owl:sameIndividualAs which is not defined in OWL. And this is because 
the food ontology used in that example is from an earlier OWL guide 
(before owl:sameIndividualAs was dropped in favor of owl:sameAs). The 
corrected food ontology is at [2] and does not have that problem. But 
this little problem has no effect on the results of that example, i.e. 
you are supposed to get answers only with the first execution of query 
and not the rest.

Cheers,
Evren
