如何在RDF类的所有实例上选择all？

Question

我正在尝试在朋友的数据集上执行选择所有查询。我对他的RDF数据集的设计有些担忧，因为每个客户端的URI都不同。在这种情况下，如何选择所有查询？这是我第一次使用RDF，所以也许我猜错了。

以下是数据：

总之，我们有

<ex:Client rdf:about="http://www.semanticweb.org/home/ontologies/2016/10/ex#Taleb"> 
<ex:Client rdf:about="http://www.semanticweb.org/home/ontologies/2016/10/ex#Djamel">

我们希望获得有关Taleb和Djamel的所有数据。除此之外，当有两个以上的客户端时，如何编写类似的查询？

Answer 1

分享您的数据真是太棒了。我做了一些编辑，因为它没有完成RDF的发布：

• 未定义ex：前缀
• 它没有打开和关闭<rdf:RDF>标签

此外

• 很多人会发现您的数据更易于以TURTLE格式阅读，而不是您发布的RDF / XML格式
• 您还应该考虑为所有实体提供人类可读的rdfs:label，例如<http://www.semanticweb.org/home/ontologies/2016/10/ex#Djamel>
• 我觉得hasValue的{​​{1}}对象DjamelFirstName而不是Nom有点奇怪。这是标签/价值混淆的情况吗？

这是您可以尝试的SO answer listing some training materials。

这里是您的数据片段，采用Turtle格式，并带有标签：

Djamel

你问题的最后两行提供了答案的提示：如果你想找到关于RDF同一类（@prefix ex: <http://www.semanticweb.org/home/ontologies/2016/10/ex#> . @prefix owl: <http://www.w3.org/2002/07/owl#> . @prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . @prefix xsd: <http://www.w3.org/2001/XMLSchema#> . @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> . ex:DjamelFirstName a ex:FirstName ; rdfs:label "Djamel's first name" ; ex:hasPurpose ex:current ; ex:hasRecipient ex:ours ; ex:hasRetention ex:no-retention ; ex:hasValue "Nom" . ex:Djamel a ex:Client ; rdfs:label "Client 'Djamel'" ; ex:hasAdress ex:DjamelAdress ; ex:hasAge ex:DjamelAge ; ex:hasBdDate ex:DjamelBdDate ; ex:hasCreditCard ex:DjamelCreditCard ; ex:hasDriverLicense ex:DjamelDriverLicense ; ex:hasFirstName ex:DjamelFirstName ; ex:hasIdentityCard ex:DjamelIdentityCard ; ex:hasLastName ex:DjamelLastName ; ex:hasPassPort ex:DjamelPassPort ; ex:hasService ex:RentVehicle . ）的两个实例的信息，你应该要求该类的所有成员。

ex:Client

查询的<ex:Client rdf:about="http://www.semanticweb.org/home/ontologies/2016/10/ex#Taleb"> <ex:Client rdf:about="http://www.semanticweb.org/home/ontologies/2016/10/ex#Djamel"> 部分来自的地方。

您的数据模型对我来说通常是合理的，但是您必须处理它嵌套的事实。例如，?s a ex:Client与表示其（？）名称的字符串文字没有直接关系。

我编写了一个查询级别的嵌套查询。如果您的数据实际使用更深层次的嵌套，则您需要修改查询。

ex:Djamel

给出

PREFIX  ex:   <http://www.semanticweb.org/home/ontologies/2016/10/ex#>
SELECT  *
WHERE
  { ?s  a    ex:Client .
    ?s  ?p1  ?o1 .
    OPTIONAL
      { ?o1  ?p2  ?o2 } .
  }
