我有一个班级MAN
。我想添加一个具有属性的个人jack
:
hasage="50"
hasadress="france"
如何创建我的个人jack
并向他添加属性并将其保存到我的文件database.owl
中?这是连接。我使用Eclipse和Jena API。
JenaOWLModel owlModel ;
OntModel model;
owlModel = ProtegeOWL.createJenaOWLModelFromURI("file:///C:/database.owl");
model = owlModel.getOntModel();
我求你帮助我,我的论文辩护仍然很好,这个CODE工作完全可以保存我的文件中的个人。但是我不能为这些人添加属性并保存它们。
请帮助我,我该怎么办,我真的非常感谢你提前感谢
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){
}
}
}

您没有说明您使用的命名空间是什么。所以我将假设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" ) );
