Hi all,

I want to know if SHACL allows defining a pattern for values in the  sh:path element, for example, something like:

  sh:property [
       sh:path ex:name??? ;
       sh:node xsd:string;
    ].
Where the part "???"  is dynamic.

This property could validate data graphs as:

ex:name01 "John"; #OK
ex:name02 "Mary; #OK
ex:name03 120;    #ERR

Hugs,

Angelo

Typically, you would define a property shape for each of the properties.
 It would not be sh:node xsd:string, but rather sh:datatype xsd:string.

Values of sh:path are specified here: https://www.w3.org/TR/shacl/#property-paths

The short answer is no, sh:paths cannot be dynamic. Your use case can be covered by SHACL-SPARQL though.

Thank you Holger and Irene,

Irene, you are correct, this line I posted wrong:
>>        sh:node xsd:string;

Hugs,
Angelo
