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‘。
数据图
@prefix inst1: <https://someHost.com/PROJ1001#> .
@prefix : <http://test.com/#> .
@prefix owl: <http://www.w3.org/2002/07/owl#> .
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix ifcowl: <https://www.buildingsmart-tech.org/ifcOWL/IFC4_ADD1#> .
@prefix s4bldg: <https://saref.etsi.org/saref4bldg/> .
@prefix bot: <https://w3id.org/bot#> .
inst1:Wall1 a ifcowl:IfcWallStandardCase ;
s4bldg:FireRating "2" ;
bot:containsSubElement inst1:Door1, inst1:Door2.
inst1:Door1 a ifcowl:IfcDoor ;
s4bldg:FireRating "2" .
inst1:Door2 a ifcowl:IfcDoor .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.
}}我想为相同的SHACL形状添加框架。在SHACL高级特性中,最接近的选项是使用sh:union。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]
)
].但是,它没有给出SPARQL查询所给出的结果。我哪里错了?任何帮助都将不胜感激。

我不清楚你是否需要一个sh:规则。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" ;
]
.它可能不是一个完整的值,您可能希望使用sh:in来指定FireRating的值范围,但这样想可能是值得的,也许您可以调整以满足您的规范。
