个人创建的 Jena 在写入文件时没有 class
Individual created Jena has no class when written in file
我的 java 程序正在读取医疗数据并将它们翻译成语义，然后我将其保存为 RDF 文件以导出它们。但是来自特定 class 的一个人始终存在于文件中，但某些属性和它的 class 丢失。
我试过更改导出格式，我已经仔细检查了所有 IRI。所有这一切都不成功。
我添加了一些代码来检查 class 和属性，然后在 RDF 文件中写入模型，一切似乎都是正确的。
创建 ontology 的代码：
public static Individual createIndiv(String name, Resource ressource) { // Create an Individual
if (populateModel==null) {populateModel = ModelFactory.createOntologyModel();}
if (name==null || ressource==null) {
logger.error("Creating Individual named "+name+" with classs "+ressource.getLocalName());
return null;
} else {
logger.debug("Creating Individual named "+name+" with classs "+ressource.getLocalName());
System.out.println(ressource);
Individual ind = populateModel.createIndividual(racineURI+name, ressource);
return ind;
}
}
Individual imagingStudy = createIndiv(generateName("imaging_study_TEST"), model.getResource("http://medicis.univ-rennes1.fr/ontologies/ontospm/OntoMEDIRAD.owl#imaging_study"));
写作前要检查的测试：
System.out.println("Test Final :");
System.out.println("RDF Type :"+imagingStudy.getRDFType());
StmtIterator propertiesIter = imagingStudy.listProperties();
Statement p;
while (propertiesIter.hasNext()) {
p = propertiesIter.next();
System.out.println(p.asTriple());
}
编写模型的代码：
public void writingRDF(String pathOut) throws FileNotFoundException { // Write the RDF
logger.info("Writing RDF file in "+pathOut);
FileOutputStream sortie = new FileOutputStream(pathOut);
OntologyPopulator.populateModel.write(sortie, "RDF/XML", null);
logger.info("Writing RDF file Sucessfull");
OntologyPopulator.populateModel = ModelFactory.createOntologyModel();
}
