如何使用SPARQL构造一个acl形状

Question

我有一个ttl文件，其中包含以下信息:

ex:Shape1
a sh:NodeShape ;
sh:property ex:Property-1
rdfs:label "Shape 1"
ex:Property-1
a sh:PropertyShape ;
sh:path ex:property1
sh:name "Property 1"
ex:property1
a owl:DatatypeProperty

将上述数据加载到我的三重存储(其中已经包含许多形状)后，我可以使用什么查询来检索相同的数据回来?

我尝试了一些事情，我得到的最接近的是下面的查询，它返回我的三重存储中的每个形状(但不是ex:property1):

PREFIX sh: <http://www.w3.org/ns/shacl#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX owl: <http://www.w3.org/2002/07/owl#>
PREFIX ex: <http://example.com/#>
CONSTRUCT {
?subject ?predicate ?object
}
WHERE {
ex:Shape1 sh:property ?propertyShape .
{ ex:Shape1 ?predicate ?object } UNION {  ?propertyShape ?predicate ?object }
?subject ?predicate ?object .
}

Answer 1

这个查询似乎做了我需要的:

PREFIX sh: <http://www.w3.org/ns/shacl#>
PREFIX ex: <http://example.com/#>
CONSTRUCT {
?subject ?predicate ?object
}
WHERE {
{
bind(ex:Shape1 as ?subject)
ex:Shape1 ?predicate ?object
}
UNION
{
ex:Shape1 sh:property ?subject .
?subject ?predicate ?object
}
UNION
{
ex:Shape1 sh:property/sh:path ?subject .
?subject ?predicate ?object
}
}
