From RDF Data Shapes Working Group
This page collects examples of shapes for two syntax variations of SHACL. The first one is the current syntax. The second is based on merging sh:Shape and sh:NodeConstraint into a single class, and dropping sh:constraint.
Example: Closed shape
ex:ClosedShape
a sh:Shape ;
sh:constraint [
sh:closed true ;
sh:ignoredProperties ( rdf:type ) ;
] ;
sh:property [
sh:predicate ex:onlyProperty ;
] .
ex:ClosedShape
a sh:Shape ;
sh:closed true ;
sh:ignoredProperties ( rdf:type ) ;
sh:property [
sh:predicate ex:onlyProperty ;
] .
Example: Values must be either strings or ex:Addresses
ex:PersonShape
a sh:Shape ;
sh:property [
sh:predicate ex:address ;
sh:or (
[
sh:constraint [
sh:datatype xsd:string ;
]
]
[
sh:constraint [
sh:class ex:Address ;
]
]
) ;
] .
ex:PersonShape
a sh:Shape ;
sh:property [
sh:predicate ex:address ;
sh:or (
[
sh:datatype xsd:string ;
]
[
sh:class ex:Address ;
]
) ;
] .
Example: Rectangle with Area
"A Rectangle must either have width and height, or an area"
ex:RectangleWithAreaShape
a sh:Shape ;
sh:constraint [
sh:or (
[
sh:property [
sh:predicate ex:height ;
sh:minCount 1 ;
] ;
sh:property [
sh:predicate ex:width ;
sh:minCount 1 ;
] ;
]
[
sh:property [
sh:predicate ex:area ;
sh:minCount 1 ;
] ;
]
) ;
] .
ex:RectangleWithAreaShape
a sh:Shape ;
sh:or (
[
sh:property [
sh:predicate ex:height ;
sh:minCount 1 ;
] ;
sh:property [
sh:predicate ex:width ;
sh:minCount 1 ;
] ;
]
[
sh:property [
sh:predicate ex:area ;
sh:minCount 1 ;
] ;
]
) .
