无法加载导入的本体HTTP响应代码：403

问题描述：

我有以下存储在OWL文件中的本体（https://raw.githubusercontent.com/wiki/ontop/ontop/attachments/Example_MovieOntology/movieontology.owl）。无法加载导入的本体HTTP响应代码：403

我试图加载：

OWLOntologyManager manager = OWLManager.createOWLOntologyManager(); 
File file = new File("movieontology.owl"); 
OWLOntology ontology = manager.loadOntologyFromOntologyDocument(file);

但我得到这个异常：

如果我试图通过本体（WebVOWL）基于Web的可视化加载本体，它加载没有任何问题。我该如何解决？

适合我。你应该再试一次。该网址在线。 – AKSW

@AKSW我可以从浏览器访问url，但是从IDE中我得到了异常。 – vincentdj

“http：// dbpedia.org/ontology /”的内容协商看起来不适用于导入。 – AKSW

答

移至OWLAPI 4.2.3。内容协商已升级，并应处理调用者知道如何解析的任何格式。

如果这不行，请在github上的OWLAPI跟踪器中提出问题。

我已经在使用OWLAPI 4.3.1。它适用于@AKSW的建议，但忽略导入。我会说，猫头鹰加载器解释'http：// dbpedia.org/ontology /'导入。 – vincentdj
