Virtuoso R2RML rr：IRI生成

我在Virtuoso中生成rr:termTyperr:IRI時遇到問題。我不知道我是否做錯了，但我遵循W3C規範。Virtuoso R2RML rr：IRI生成

我的映射看起來像這樣。當我使用CONSTRUCT聲明生成三元組時，我仍然得到"URL"但不是IRI => <url>（OWNER_LINK和BRAND_LINK列）。這是Virtuoso不支持的東西，還是我編碼錯了？

所以我想通了，我的代碼是錯誤的，應該是這樣的

rr:predicateObjectMap 
    [ 
     rr:predicateMap 
      [ 
      rr:constant s:url 
      ]; 
     rr:objectMap 
      [ 
      rr:termType rr:IRI   ; 
      rr:template "{BRAND_LINK}" ; 
      ]; 

    ];.

，它的工作

謝謝。

需要明確的是 - 你說的R2RML映射成功加載，但運行SPARQL CONSTRUCT查詢時，不顯示在結果中rr:termType rr:IRI映射設置？

As the docs indicate，只有rr:sqlQuery目前不支持......

是的我沒有得到任何結果集你知道我在做什麼錯嗎？在與Virtuoso合作時，我真的感到很沮喪 – James 2014-11-10 23:03:26
