[英]SHACL union shapes
I have framed a SPARQL query for the following use-case: If IfcWallStandardCase have a property 'FireRating', then the doors associated with it should have a property 'FireRating' as well.我为以下用例构建了一个 SPARQL 查询:如果 IfcWallStandardCase 有一个属性“FireRating”,那么与之关联的门也应该有一个属性“FireRating”。

SPARQL Query SPARQL 查询
SELECT ?door
WHERE {{
?wall rdf:type ifcowl:IfcWallStandardCase.
?wall bot:containsElement ?val.
?wall s4bldg:FireRating ?val.
}UNION{
?door rdf:type ifcowl:IfcDoor.
?door s4bldg:FireRating ?val.
}}
I want to frame a SHACL shape for the same.我想为相同的形状构建一个 SHACL 形状。 From the SHACL advanced features, the closest option is to use the sh:union.从 SHACL 高级功能中,最接近的选项是使用 sh:union。 Below, is my shape.下面,是我的形状。
bot:BuildingShape
a sh:NodeShape ;
sh:targetClass ifcowl:IfcWallStandardCase;
sh:rule [
sh:subject sh:this;
sh:predicate s4bldg:FireRating;
sh:object ifcowl:IfcWallStandardCase;
sh:union(
[sh:path ifcowl:IfcDoor]
[sh:path s4bldg:FireRating]
)
].
But, it does not give me the result given by the SPARQL query.但是,它没有给我 SPARQL 查询给出的结果。 Where am I going wrong?我哪里错了? Any help would be appreciated.任何帮助,将不胜感激。
It's not clear to me that you need a sh:rule for this.我不清楚您是否需要 sh:rule 为此。 Try the following:请尝试以下操作:
bot:BuildingShape
a sh:NodeShape ;
sh:targetClass ifcowl:IfcWallStandardCase;
sh:property [
sh:path bot:containsSubElement;
sh:class ifcowl:IfcDoor ;
] ;
sh:property [
sh:path s4bldg:FireRating;
sh:hasValue "2" ;
]
.
It may not be a full value, and you may want to use sh:in to specify the range of values for FireRating, but it may be worth thinking of it this way and maybe you can tweak to meet your specification.它可能不是一个完整的值,您可能想使用 sh:in 来指定 FireRating 的值范围,但可能值得以这种方式考虑它,也许您可以进行调整以满足您的规范。
