In fact, on page 16 of Open Knowledge Base Connectivity 2.0.3 (Proposed), which is the most recent document I could find, there is the statement: Note that if slot :DOMAIN of a slot S has multiple values C1,...,Cn then the domain of slot S is constrained to be the intersection of classes C1,...,Cn. which indicates to me that OKBC using the conjunctive semantics for domains of slots. peterReceived on Friday, 15 September 2000 17:08:02 UTC
