SHACL：要求SH：财产成为URI

发布于 2025-02-07 22:29:13 字数 1057 浏览 2 评论 0原文

我想知道是否有一种方法可以指定给定的sh：属性有望在没有任何特定类的情况下具有URI的值。

在下面的示例SHACL中，属性meta：value只允许URI，尽管我不知道在SHACL中表示它的方法。

示例SHACL

@prefix sh: <http://www.w3.org/ns/shacl#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

@prefix meta: <metadata#> .
@prefix meta_sh: <metadata/shacl#> .

meta_sh:Entry
    a sh:NodeShape;
    sh:targetClass meta:Entry;
    sh:property [
        sh:path meta:value;
        # Value expected to be a URI
        sh:minCount 1; # Required; 1 or more
    ];
    sh:property [
        sh:path meta:time;
        sh:datatype xsd:dateTime;
        sh:minCount 1; sh:maxCount 1; # Required; 1
    ];
    .

示例数据

@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

@prefix meta: <metadata#> .
@prefix data: <data#> .

data:Entry_001
    a meta:Entry;
    meta:value data:ProductListing_459; # URI
    meta:value data:RentalListing_934; # URI
    meta:time "2022-06-15T06:20:31Z"^^xsd:dateTime;
    .

I was wondering if there's a way to specify that a given sh:property is expected to have a value of a URI without any particular class.

In the example SHACL below, the property meta:value would only allow URIs, although I don't know of a way to represent it in SHACL.

Example SHACL

@prefix sh: <http://www.w3.org/ns/shacl#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

@prefix meta: <metadata#> .
@prefix meta_sh: <metadata/shacl#> .

meta_sh:Entry
    a sh:NodeShape;
    sh:targetClass meta:Entry;
    sh:property [
        sh:path meta:value;
        # Value expected to be a URI
        sh:minCount 1; # Required; 1 or more
    ];
    sh:property [
        sh:path meta:time;
        sh:datatype xsd:dateTime;
        sh:minCount 1; sh:maxCount 1; # Required; 1
    ];
    .

Example Data

@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

@prefix meta: <metadata#> .
@prefix data: <data#> .

data:Entry_001
    a meta:Entry;
    meta:value data:ProductListing_459; # URI
    meta:value data:RentalListing_934; # URI
    meta:time "2022-06-15T06:20:31Z"^^xsd:dateTime;
    .

这应该有效：

@prefix sh: <http://www.w3.org/ns/shacl#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

@prefix meta: <metadata#> .
@prefix meta_sh: <metadata/shacl#> .

meta_sh:Entry
    a sh:NodeShape;
    sh:targetClass meta:Entry;
    sh:nodeKind sh:IRI ;
    sh:property [
        sh:path meta:value;
        # Value expected to be a URI
        sh:minCount 1; # Required; 1 or more
    ];
    sh:property [
        sh:path meta:time;
        sh:datatype xsd:dateTime;
        sh:minCount 1; sh:maxCount 1; # Required; 1
    ];
    .

this should work:

@prefix sh: <http://www.w3.org/ns/shacl#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

@prefix meta: <metadata#> .
@prefix meta_sh: <metadata/shacl#> .

meta_sh:Entry
    a sh:NodeShape;
    sh:targetClass meta:Entry;
    sh:nodeKind sh:IRI ;
    sh:property [
        sh:path meta:value;
        # Value expected to be a URI
        sh:minCount 1; # Required; 1 or more
    ];
    sh:property [
        sh:path meta:time;
        sh:datatype xsd:dateTime;
        sh:minCount 1; sh:maxCount 1; # Required; 1
    ];
    .

是的，您是对的，sh：nodekind必须成为属性形状的一部分。

它仍然无法使用的原因：定义前缀的方式。它们不是完整的URIS，因此SHACL处理器添加了一些零件（也许是文件的磁盘位置取决于）。结果：形状中的meta在数据中与meta不匹配。

这起作用：

SHACL

@prefix sh: <http://www.w3.org/ns/shacl#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

@prefix meta: <https://example.org/#> .
@prefix meta_sh: <metadata/shacl#> .

meta_sh:Entry
    a sh:NodeShape;
    sh:targetClass meta:Entry;
    sh:property [
        sh:path meta:value;
        sh:nodeKind sh:IRI ;
        sh:minCount 1; # Required; 1 or more
    ];
.

数据

@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

@prefix meta: <https://example.org/#> .
@prefix data: <data#> .

data:Entry_001
    a meta:Entry;
    meta:value data:RentalListing_934 ; # URI
    meta:time "2022-06-15T06:20:31Z"^^xsd:dateTime;
.

data:Entry_002
    a meta:Entry;
    meta:value "this is not an uri" ; # No Uri
    meta:time "2022-06-15T06:20:31Z"^^xsd:dateTime;
.

Yes, you are right, the sh:nodeKind has to be part of the property shape.

The reason why it still not worked: the way you defined the prefixes. They were no full URIs so the SHACL processor added some parts (maybe the disk location of the file, depends). The result: the meta in the shapes never matched the meta in the data.

This works:

SHACL

@prefix sh: <http://www.w3.org/ns/shacl#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

@prefix meta: <https://example.org/#> .
@prefix meta_sh: <metadata/shacl#> .

meta_sh:Entry
    a sh:NodeShape;
    sh:targetClass meta:Entry;
    sh:property [
        sh:path meta:value;
        sh:nodeKind sh:IRI ;
        sh:minCount 1; # Required; 1 or more
    ];
.

Data

@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

@prefix meta: <https://example.org/#> .
@prefix data: <data#> .

data:Entry_001
    a meta:Entry;
    meta:value data:RentalListing_934 ; # URI
    meta:time "2022-06-15T06:20:31Z"^^xsd:dateTime;
.

data:Entry_002
    a meta:Entry;
    meta:value "this is not an uri" ; # No Uri
    meta:time "2022-06-15T06:20:31Z"^^xsd:dateTime;
.
