我们现在有成型的OWL数据,但是采用protege打开的时候,因为数据量太大,出现heap space的问题.
所以就用不了protege直接的界面操作工具(用protege将owl转为sql database).

考虑protege是否有某些开源的class,可以做到owl->数据库的转换工作.

我们目前知道的有 http://protege.stanford.edu/download/prerelease_javadoc_owl/edu/stanford/smi/protegex/owl/database/OWLDatabaseModel.html

这是OWL database的包, 看起来有些复杂,这个class和其他的类有相关性.

不知道有没有直接的API接口可以做?其数据库中数据的关系描述(如类,属性,实例等)是如何描述的?

现在是在摸黑做,所以想知道别人是否做过这样的工作,有些什么经验或者是相关文献可以参考.

谢谢

Method 1   
The simplest way to load an OWL Database project is to load programmatically the project (pprj file), which already contains all database connection information:

Project prj = Project.loadProjectFromFile("/home/pizza_db.pprj",errors);
OWLModel owlModel = (OWLModel) prj.getKnowledgeBase();
...

Method 2
The second method should be used if there is no project file (.pprj) associated with the OWL Database ontology.  

OWLDatabaseKnowledgeBaseFactory factory = new OWLDatabaseKnowledgeBaseFactory();         
Project prj = Project.createNewProject(factory, errors);
OWLDatabaseKnowledgeBaseFactory.setSources(prj.getSources(), "com.mysql.jdbc.Driver", "jdbc:mysql://localhost:3306/protege", "pizza", "user", "password");
prj.createDomainKnowledgeBase(factory, errors, true);

OWLModel owlModel = (OWLModel) prj.getKnowledgeBase();

我不知道还没有其他方法，欢迎讨论！！
