添加属性到individual，并将它们全部插入到我的file.owl中

Question

我有一个类，MAN。我想添加一个个体，jack，属性:

 hasage="50"
 hasadress="france"

我如何创建我的个人jack和添加属性给他，并将它们保存到我的文件database.owl ?这就是其中的联系。我使用Eclipse和Jena API。

  JenaOWLModel owlModel ;
  OntModel model;           
  owlModel = ProtegeOWL.createJenaOWLModelFromURI("file:///C:/database.owl");
  model = owlModel.getOntModel();

我恳求你帮助我，我的论文答辩还有几天，这个代码工作完美，我可以在我的文件中保存个人。但是我不能为这些个体添加属性并保存它们

请帮帮我，我该怎么办，我真的很担心，提前谢谢你了

     public class testins { 
static JenaOWLModel owlModel ;
public static void main(String[] args) {
OntModel model;
javax.swing.JDialog jDialog1 = new javax.swing.JDialog();
try{        
    owlModel = ProtegeOWL.createJenaOWLModelFromURI("file:///D:/file.owl");//  the link of my owl file
    model = owlModel.getOntModel(); 
    JOptionPane.showMessageDialog(jDialog1,
    "loaded with success","Information",JOptionPane.INFORMATION_MESSAGE);       
   }
catch(Exception e){
    JOptionPane.showMessageDialog(jDialog1,
            "error",
            "Information",
            JOptionPane.INFORMATION_MESSAGE);
}   

OWLNamedClass theAlert = owlModel.getOWLNamedClass("Alert"); //my class Alert
theAlert.createOWLIndividual("indivname1"); //i add here an indevidual
theAlert.createOWLIndividual("indivname2"); //i add here another indevidual
// now how to add to those two Individuals properties ?? each individual has 2
// properties , the property witch its name est_evaluer and the second est_analyser those 
// to properties will contain values so here is my problem how to add those values to an
// individual and save all of them

       Collection errors ;
       String fileName ;           
       fileName= ("D:/file.owl");
       errors = new ArrayList();
//here i'll save it and it work ,it mean that i find in my file "file.owl" 
//individuals i added witch are "indivname1" and "indivname2" in my class ALERT 
// so now my problem is how to add properties to those indiviuals i add , and save them also
    try{  owlModel.save(new File(fileName).toURI(), FileUtils.langXMLAbbrev, errors);
    System.out.println("File saved with " + errors.size() + " errors.");
  }
  catch(Exception e){         
  }
   }   

}

您没有说明您正在使用的名称空间是什么。所以我假设是http://example.org/example#，根据需要进行调整。

String NS = "http://example.org/example#";
// create ex:Man class
OntClass man = model.createClass( NS + "Man" );
// create individual ex:jack
Individual jack = model.createIndividual( NS + "jack", man );
// create some properties - probably better to use FOAF here really
DatatypeProperty age = model.createDatatypeProperty( NS + "age" );
DatatypeProperty address = model.createDatatypeProperty( NS + "address" );
jack.addProperty( age, model.createTypedLiteral( 50 ) )
    .addProperty( address, model.createLiteral( "France" ) );
