下面是java代码：

InputStream in = FileManager.get().open(filename);
if (in == null) {
    throw new IllegalArgumentException("File: " + filename + " not found");
}
model = ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM);
model.read(in, null);
try {
    in.close();
} catch (IOException e) {
    System.err.println("Couldn't close the inputStream");
}

这有帮助吗？我真的不知道了...

这是一个OWL2 XML格式的文件。Jena不支持这种格式，但它支持RDF/XML中的OWL。

换句话说，它对XML的期望是错误的，并因此变得混乱。

请尝试将其保存为其他格式。
