Question

每当我在某些人身上调用“.getOntClass（）”时，我都注意到Jena给了我一个转换错误。我做了一些进一步的测试，当我在某些人上调用“.getRDFType（）”时，它错误地返回“http://www.w3.org/2002/07/owl#NamedIndividual”而不是本体中陈述的正确的rdf：类型。以下是本体中涉及的个人：

当我在其上调用“.getRDFType（）”时，第一个人（Haas-DM1VerticalMill）正确返回“http://infoneer.txstate.edu/ontology/MSDL_0000076”。但另外两个人（Haas-DM2VerticalMill和Haas-VF1VerticalMill）错误地返回“http://www.w3.org/2002/07/owl#NamedIndividual”而不是“http://infoneer.txstate.edu/ontology/MSDL_0000076”。

奇怪的是，当我摆脱两个问题个体中的“msdl：MSDL_0000179 rdf：resource =”http://infoneer.txstate.edu/ontology/MSDL_0000154“”这一行时，“。getRDFType（）”返回“ http://infoneer.txstate.edu/ontology/MSDL_0000076“应该如此。我不知道为什么会这样，特别是考虑到Haas-DM1个人也有这条线，并且包含它的工作正常。

将严格模式设置为false不会改变任何内容。有什么帮助吗？

Jena奇怪地认为个人rdf：type是随机个体的“#NamedIndividual”
