I now have:

 

nen2660:QuantityValue

  a owl:Class ;

  rdfs:subClassOf [

      a owl:Restriction ;

      owl:allValuesFrom xsd:double ;

      owl:onProperty rdf:value ;

    ] ;

.

 

 

People want tof lex this into a double or a decimal

In owl its clear

But in this shacl I get:

nen2660:QuantityValue

  rdf:type rdfs:Class ;

  rdf:type sh:NodeShape ;

  rdfs:seeAlso nen2660-term:QuantityValue ;

  rdfs:subClassOf nen2660:Objectification ;

  skos:definition "The objectification of a value of a quantity (involving a quantitykind and a unit) having a complex value like a simple value sec combined with other metadata or just a combination of simple values"@en ;

  skos:prefLabel "Quantity value"@en ;

  sh:property [

      sh:path rdf:value ;

      sh:datatype [

          rdf:type owl:Class ;

          owl:unionOf (

              xsd:double

              xsd:decimal

            ) ;

        ] ;

    ] ;

.

 

Ie a piece of owl is introduced…after:

Isn’t there a more shacl-native way to do this?

 

Thx michel

OWL logic cannot be used in SHACL.

We provide these resources to answer to this kind of question:


SHACL and OWL Compared at https://spinrdf.org/shacl-and-owl.html

where you find this:

Logical Constraints
owl:complementOf sh:not
owl:intersectionOf sh:and
owl:unionOf sh:or
owl:qualifiedMin/MaxCardinality 1 sh:xone
owl:disjointUnionOf sh:node/sh:or/sh:not

Cheers,
David

That is good news.

But tbc does it when I add ‘x or y’ in the form……

 

So how would:

 

nen2660:QuantityValue

  rdf:type rdfs:Class ;

  rdf:type sh:NodeShape ;

  rdfs:seeAlso nen2660-term:QuantityValue ;

  rdfs:subClassOf nen2660:Objectification ;

  skos:definition "The objectification of a value of a quantity (involving a quantitykind and a unit) having a complex value like a simple value sec combined with other metadata or just a combination of simple values"@en ;

  skos:prefLabel "Quantity value"@en ;

  sh:property [

      sh:path rdf:value ;

      sh:datatype [

          rdf:type owl:Class ;

          owl:unionOf (

              xsd:double

              xsd:decimal

            ) ;

        ] ;

    ] ;

.

 

Look like in pure shacl?

If it’s adding OWL structures then you are using the Composer OWL editing forms - so stop doing that. Import SHACL and drag in the needed SHACL properties (or edit in text editor for even more control).

As I pasted below, owl:unionOf is similar to sh:or so remove the owl:Class stuff and try that.

Cheers,
