I’m building constraints for form building, and I'm wondering the best way to constrain a PropertyShape to say for a given property not only link to individuals of a particular class type, but also individuals from a particular scheme.

For example, in the following we want to use the property rdau:P60552 to link to individuals skos:inScheme <http://rdaregistry.info/termList/configPlayback> .

sh:property [
sh:path <http://rdaregistry.info/Elements/u/P60552> ;
sh:class <http://www.w3.org/2004/02/skos/core#Concept> ;
sh:description "Relates a resource to a number of sound channels used to make a recording." ;
sh:name "Has playback channels" ;
sh:nodeKind sh:IRI ;

I have a feeling based on the SHACL spec the answer is somewhere in the SPARQL-based constraints, but could someone confirm?

Thanks in advance for any pointers,

Steven

Steven,

sh:path can be used for paths, not just for single properties

So, you can place another property constraint to say that the value of http://rdaregistry.info/Elements/u/P60552/skos:inScheme path must be http://rdaregistry.info/termList/configPlayback. You can use sh:hasValue constraint for this.

Irene,

Thanks this is helpful. If I want to say the value used with a property can come from one or more acceptable schemes, I'm guessing that I'll need to use sh:or, right? (Since sh:hasValue says at least one value node is equal to the given term.)

E.g. Let's see if I can get this right...

sh:property [
sh:path http://rdaregistry.info/Elements/u/P60552/skos:inScheme ;
sh:nodeKind sh:IRI ;

sh:or (
[ sh:value <http://rdaregistry.info/termList/configPlayback> ;

]

[ sh:value <http://xyz.org/otherscheme> ;

]

) ;

];

Thanks,

Steven
