mysql jena rdf_使用xml文件中的jena创建RDF三元组和RDF存储

我使用下面的java程序从xml文件中提取信息。

import java.io.File;

import java.net.URL;

import org.w3c.dom.*;

import javax.xml.parsers.DocumentBuilderFactory;

import javax.xml.parsers.DocumentBuilder;

import org.xml.sax.SAXException;

import org.xml.sax.SAXParseException;

public class ExtractInfo {

public static void main(String argv []) {

try {

DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();

DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();

File file = new File("page.xml");

Document doc = docBuilder.parse(file);

// normalize text representation

doc.getDocumentElement().normalize();

System.out.println ("Root element of the doc is " +

doc.getDocumentElement().getNodeName());

NodeList listOfPersons = doc.getElementsByTagName("person");

int totalPersons = listOfPersons.getLength();

System.out.println("Total no of people : " + totalPersons);

for (int s=0; s

Node firstPersonNode = listOfPersons.item(s);

if (firstPersonNode.getNodeType() == Node.ELEMENT_NODE) {

Element firstPersonElement = (Element)firstPersonNode;

//-------

NodeList firstNameList = firstPersonElement.getElementsByTagName("first");

Element firstNameElement = (Element)firstNameList.item(0);

NodeList textFNList = firstNameElement.getChildNodes();

System.out.println("First Name : " +

((Node)textFNList.item(0)).getNodeValue().trim());

//-------

NodeList lastNameList = firstPersonElement.getElementsByTagName("last");

Element lastNameElement = (Element)lastNameList.item(0);

NodeList textLNList = lastNameElement.getChildNodes();

System.out.println("Last Name : " +

((Node)textLNList.item(0)).getNodeValue().trim());

//----

NodeList ageList = firstPersonElement.getElementsByTagName("age");

Element ageElement = (Element)ageList.item(0);

NodeList textAgeList = ageElement.getChildNodes();

System.out.println("Age : " +

((Node)textAgeList.item(0)).getNodeValue().trim());

}

}

} catch (SAXParseException err) {

System.out.println ("** Parsing error" + ", line "

+ err.getLineNumber () + ", uri " + err.getSystemId());

System.out.println(" " + err.getMessage());

} catch (SAXException e) {

Exception x = e.getException ();

((x == null) ? e : x).printStackTrace();

} catch (Throwable t) {

t.printStackTrace();

}

}

}有人可以帮助我从提取的信息中生成RDF三元组，并使用包含所有三元组的Jena创建三重商店。我对RDF和耶拿很新，所以我确实需要你们的帮助，

提前致谢。
