在RDF文件SPARQL嵌套元組

Question

如何寫SPARQL爲包含這些類型的元組的

<rdf:Description rdf:about="http://example.com/BEROVO"> 
      <j.0:destDetails rdf:resource="http://example.com/0c64a8f2-fd39-4e9d-a03b-527359af8661"/> 
      <j.0:destDetails rdf:resource="http://example.com/31dd238d-0356-4d78-b6fb-26647902ecd3"/> 
      <j.0:destDetails rdf:resource="http://example.com/76248058-5dd1-42a5-b988-affcf732ac6a"/> 
      <j.0:destDetails rdf:resource="http://example.com/f8541d66-4107-464a-bc31-60df76a4f7a4"/> 
      <j.0:destDetails rdf:resource="http://example.com/1298d38c-e69f-42ca-a329-f0cd8091a524"/> 
      <j.0:destDetails rdf:resource="http://example.com/5122c7a1-ca0d-4302-84ad-fea4909e8551"/> 
      <j.0:destDetails rdf:resource="http://example.com/cb25a063-0787-4079-8e4a-21e3440df8c3"/> 
      <j.0:destDetails rdf:resource="http://example.com/f72eeb27-4852-4737-b248-338bc05206b4"/> 
      <j.0:destDetails rdf:resource="http://example.com/0fc999e9-0a5a-4555-a7bf-6a4a41508ae8"/> 
      <j.0:destDetails rdf:resource="http://example.com/3303225e-f2dd-4712-9cb3-d10a69bd4357"/> 
      <j.0:destDetails rdf:resource="http://example.com/31d37728-a72d-445e-b554-d5cdc91830e5"/> 
</rdf:Description> 
<rdf:Description rdf:about="http://example.com/0c64a8f2-fd39-4e9d-a03b-527359af8661"> 
      <j.0:distrName>BEROVOTRANS-BEROVO</j.0:distrName> 
      <j.0:moneyTwoDir>520 den.</j.0:moneyTwoDir> 
      <j.0:moneyOneDir>420 den.</j.0:moneyOneDir> 
      <j.0:hasTimeStop>17:15</j.0:hasTimeStop> 
      <j.0:hasTimeStart>13:20</j.0:hasTimeStart> 
</rdf:Description> 

對於從元組列表我想獲得信息的屬性每一個項目一個RDF文件：

• j.0:distrName，
• j.0:moneyTwoDir，
• j.0:moneyOneDir，
• j.0:hasTimeStop和
• j.0:hasTimeStart。

雖然Turtle和SPARQL的語法並不完全相同，但很多Turtle表達式都適合作爲SPARQL模式。如果我們把你的數據的輕微修改（使之成爲完整的RDF文件），我們得到：

<rdf:RDF xmlns:j.0="http://example.com/" 
     xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"> 
    <rdf:Description rdf:about="http://example.com/BEROVO"> 
    <j.0:destDetails rdf:resource="http://example.com/0c64a8f2-fd39-4e9d-a03b-527359af8661"/> 
    <j.0:destDetails rdf:resource="http://example.com/31dd238d-0356-4d78-b6fb-26647902ecd3"/>

    </rdf:Description> 
    <rdf:Description rdf:about="http://example.com/0c64a8f2-fd39-4e9d-a03b-527359af8661">

    <j.0:moneyOneDir>420 den.</j.0:moneyOneDir> 
    <j.0:hasTimeStop>17:15</j.0:hasTimeStop> 
    <j.0:hasTimeStart>13:20</j.0:hasTimeStart> 
    </rdf:Description> 
</rdf:RDF> 

使用耶拿的rdfcat工具，我們可以在龜得到這樣的：

$ rdfcat -out Turtle data.rdf 
@prefix rdf:  <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . 

<http://example.com/BEROVO> 
     <http://example.com/destDetails> 
       <http://example.com/31dd238d-0356-4d78-b6fb-26647902ecd3> , <http://example.com/5122c7a1-ca0d-4302-84ad-fea4909e8551> , <http://example.com/cb25a063-0787-4079-8e4a-21e3440df8c3> , <http://example.com/3303225e-f2dd-4712-9cb3-d10a69bd4357> , <http://example.com/0c64a8f2-fd39-4e9d-a03b-527359af8661> , <http://example.com/1298d38c-e69f-42ca-a329-f0cd8091a524> , <http://example.com/31d37728-a72d-445e-b554-d5cdc91830e5> , <http://example.com/0fc999e9-0a5a-4555-a7bf-6a4a41508ae8> , <http://example.com/76248058-5dd1-42a5-b988-affcf732ac6a> , <http://example.com/f72eeb27-4852-4737-b248-338bc05206b4> , <http://example.com/f8541d66-4107-464a-bc31-60df76a4f7a4> . 

<http://example.com/0c64a8f2-fd39-4e9d-a03b-527359af8661> 
     <http://example.com/distrName> 
       "BEROVOTRANS-BEROVO" ; 
     <http://example.com/hasTimeStart> 
       "13:20" ; 
     <http://example.com/hasTimeStop> 
       "17:15" ; 
     <http://example.com/moneyOneDir> 
       "420 den." ; 
     <http://example.com/moneyTwoDir> 
       "520 den." . 

果然，這幾乎是相應的SPARQL查詢會是什麼樣子：

prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> 

select ?details ?name ?moneyTwoDir ?moneyOneDir ?timeStop ?timeStart where { 

    <http://example.com/BEROVO> 
    <http://example.com/destDetails> 
     ?details . 

    ?details 
    <http://example.com/distrName> 
     ?name ; 
    <http://example.com/hasTimeStart> 
     ?timeStart ; 
    <http://example.com/hasTimeStop> 
     ?timeStop ; 
    <http://example.com/moneyOneDir> 
     ?moneyOneDir ; 
    <http://example.com/moneyTwoDir> 
     ?moneyTwoDir . 
} 

您可以查詢了一下清潔劑，如果你w ^螞蟻：

prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> 
prefix ex: <http://example.com/> 

select ?details ?name ?moneyTwoDir ?moneyOneDir ?timeStop ?timeStart where { 

    ex:BEROVO ex:destDetails ?details . 

    ?details ex:distrName ?name ; 
      ex:hasTimeStart ?timeStart ; 
      ex:hasTimeStop ?timeStop ; 
      ex:moneyOneDir ?moneyOneDir ; 
      ex:moneyTwoDir ?moneyTwoDir . 
} 

結果如你所期望的：

$ arq --data data.rdf --query query.sparql 
--------------------------------------------------------------------------------------------------------------------- 
| details         | name     | moneyTwoDir | moneyOneDir | timeStop | timeStart | 
===================================================================================================================== 
| ex:0c64a8f2-fd39-4e9d-a03b-527359af8661 | "BEROVOTRANS-BEROVO" | "520 den." | "420 den." | "17:15" | "13:20" | 
---------------------------------------------------------------------------------------------------------------------
