W3CHINA.ORG讨论区--用progete源代码怎么把本体持久化到mysql数据库中？

OWL的持久化可以用jena或protege。
原来jena 的owl持久化已经忘了，可以看下
Jena2 Database Interface - How To Create Persistent Models
用protege也是比较简单的：http://protegewiki.stanford.edu/index.php/ConvertingToDatabaseProject
下面是我仿造写的方法：
读：
package com.demo.application;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.net.URI;
import java.util.ArrayList;
import java.util.Collection;
import java.util.List;
import java.util.Map;

public class OWLConnectDBreader {
public static void main(String[] args) {
  String driver = "com.mysql.jdbc.Driver";
  String url = "jdbc:mysql://localhost/223";
  String table = "owltab1";
  String user = "root";
  String password = "root";
  //String uri = "file:f:/123.owl";

// @SuppressWarnings("unchecked");

try{ OWLDatabaseKnowledgeBaseFactory factory = new OWLDatabaseKnowledgeBaseFactory();
  Collection errors = new ArrayList();
  Project prj = Project.createNewProject(factory, errors);
  OWLDatabaseKnowledgeBaseFactory.setSources(prj.getSources(), driver,url, table, user, password);
  prj.createDomainKnowledgeBase(factory, errors, true);
  System.out.print("2323333333333333333333");
  OWLModel  owlmodel = (OWLModel) prj.getKnowledgeBase();
  } catch (Exception e) {

}
}
}

先写到数据库中，再读。
本人已经学习progete API 2个月了，对一般的操作有一定的认识，现在自己在做个系统。自己觉得学习owl还是找对应的英文文档看。
jena的文档：看它自己的文档file:///F:/Jena-2.5.7/doc/documentation.html
protege的文档：http://protege.stanford.edu/plugins/owl/api/guide.html#Jena
