定制本體和RDF

Question

我使用Protege創建了自定義的OWL本體，該本體以基於樹的RDF / XML格式序列化。

我想做的是根據自定義本體中的預定義類創建RDF三元組並將其存儲在RDF文件中。 並使用SPARQL查詢這些三元組。 我怎樣才能做到這一點？

===更新===

這是我的自定義本體的外觀，它具有Comment類和isAbout對象屬性。

我的RDF文件看起來像

      </cmnt:Display>
    </cmnt:isAbout>
</cmnt:Comment>
</rdf:RDF>

所以我無法弄清楚從Comment類創建的注釋方式。

我不能寫類似的東西嗎？

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

Answer 1

RDF / XML是RDF。 任何接受SPARQL查詢的存儲庫或庫都應通過庫支持的任何加載機制原樣接受文件。 例如，Jena和ARQ可以將其作為庫處理，而Fuseki可以作為SPARQL端點處理。
