jena - Jena递归推理问题

Question

在下面的示例中，infM 没有推断出 {r myProperty v}，有什么想法吗？

但是，它确实从 mySameAs 断言语句中推断出 {r owl:sameAs r1}。但如果我写：

this.infM = ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM_MINI_RULE_INF, this.baseM);
this.infM = ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM_MINI_RULE_INF, this.infM);

然后它还输出 {r myProperty v}

示例代码：

this.baseM = ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM);
this.infM = ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM_MINI_RULE_INF, this.baseM);

OntResource r = baseM.createOntResource(null);
OntResource r1 = baseM.createOntResource(null);
OntProperty myProperty = baseM.createOntProperty("http://example.com#my_property");
OntResource v = baseM.createOntResource("http://example.com#a_value");
OntProperty mySameAs = baseM.createOntProperty("http://example.com#mySameAs");
baseM.add(mySameAs, RDFS.subPropertyOf, OWL.sameAs);

r1.addProperty(myProperty, v);
r.addProperty(mySameAs, r1);

infM.rebind();

assertTrue(infM.contains(r, myProperty, v));

这对我来说似乎是一个错误。我在 Apache Jena Jira 上将其记录为jena-61。
