無法加載導入的本體HTTP響應代碼：403

我有以下存儲在OWL文件中的本體（https://raw.githubusercontent.com/wiki/ontop/ontop/attachments/Example_MovieOntology/movieontology.owl）。無法加載導入的本體HTTP響應代碼：403

我試圖加載：

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

但我得到這個異常：

如果我試圖通過本體（WebVOWL）基於Web的可視化加載本體，它加載沒有任何問題。我該如何解決？

適合我。你應該再試一次。該網址在線。 – AKSW

@AKSW我可以從瀏覽器訪問url，但是從IDE中我得到了異常。 – vincentdj

「http：// dbpedia.org/ontology /」的內容協商看起來不適用於導入。 – AKSW

移至OWLAPI 4.2.3。內容協商已升級，並應處理調用者知道如何解析的任何格式。

如果這不行，請在github上的OWLAPI跟蹤器中提出問題。

我已經在使用OWLAPI 4.3.1。它適用於@AKSW的建議，但忽略導入。我會說，貓頭鷹加載器解釋'http：// dbpedia.org/ontology /'導入。 – vincentdj
