自定义本体和RDFs

Question

我使用Protege创建了一个定制的OWL本体，它以基于树的RDF/XML格式序列化。

我想做的是从我在自定义本体中预定义的类中创建RDF三元组，并将它们存储在RDF文件中。并使用SPARQL查询这些三元组。我怎么能这么做？

所以我想不出一个从comment类创建的注释的方法。

我就不能写点什么吗？

select *
where {
  ?Comment rdf:type ns:Review ;
}

Answer 1

RDF/XML就是RDF。接受SPARQL查询的任何存储库或库也应该通过库支持的任何加载机制接受文件原样。例如，Jena和ARQ可以将其作为库处理，而Fuseki可以作为SPARQLendpoint处理。
