Yes, I had forgotten about this. SPIN global constraints do not need rdf:type links, even though they are attached classes. I should have said Simmilarly a SPIN ask attached to a regular class (i.e., not owl:Thing or rdfs:Resource) is only run against elements of the class. Although now I'm not even sure that this is universally true. peter On 11/19/2014 02:08 PM, Holger Knublauch wrote: > > On 11/20/14, 7:01 AM, Peter F.
