Unfortunately, it looks like there's still a problem with the super/subclass
relationship even after I fixed the inconsistent property. Specifically, here's
the test code:
OntModel model =
ModelFactory.createOntologyModel(OntModelSpec.OWL_DL_MEM_RULE_INF);
FileInputStream inStream =
new FileInputStream("ontology/terrorism.xml");
model.read(inStream, null);
inStream.close();
String uriBase = model.getNsPrefixURI("");
OntClass cls = model.getOntClass(uriBase + "TerrorAttack");
System.out
.println("TerAtt: " + cls + " Super=" + cls.getSuperClass());
for (Iterator<OntClass> iter = cls.listSuperClasses(false); iter
.hasNext();) {
System.out.println("Super: " + iter.next());
}
OntClass newsEvt = model.getOntClass("NewsArticle");
System.out.println("NewsEvt is a superclass of TerrorAttack: "
+ cls.hasSuperClass(newsEvt));
Newest version of the ontology is attached. What is printed:
TerAtt: http://blsdev1.vsticorp.com/terrorism#TerrorAttack
Super=http://www.w3.org/2002/07/owl#Thing
Super: http://www.w3.org/2002/07/owl#Thing
Super: http://www.w3.org/2000/01/rdf-schema#Resource
Super: 1d20fb81:13d82ecf576:-7fec
Super: http://blsdev1.vsticorp.com/terrorism#Killing
Super: http://blsdev1.vsticorp.com/terrorism#Event
Super: 1d20fb81:13d82ecf576:-7fef
Super: 1d20fb81:13d82ecf576:-7ff8
Super: 1d20fb81:13d82ecf576:-7ff7
NewsEvt is a superclass of TerrorAttack: true
The superclass test is obviously incorrect. Not only are the NewsArticle and
TerrorAttack classes disjoint, the NewsArticle class doesn't even appear when
all the superclasses are listed. Why is the hasSuperClass() method returning
true?

As I've said, the presenting problem is at least partly caused by the illegal
use of owl:equivalentClass in the source ontology and if I remove that then the
test case (listing super classes of
#AircraftHijacking) works.
However, as I've also said, I do agree that those two rules are incorrect.
Thanks for the test case. I've recorded it as JENA-416 and applied a fix.
