Thx Irene All clear. In our guide we combine shacl with rdfs/owl for the props so I will reuse the subclassof/subpropertyof of rdfs... (i.s.o. the shacl and-expression for the classes)

From: topbraid-users@googlegroups.com <topbraid-users@googlegroups.com> On Behalf Of Irene Polikoff Sent: dinsdag 23 april 2019 17:40 To: topbraid-users@googlegroups.com Subject: Re: [topbraid-users] owl <> shacl It depends on what you are trying to accomplish. Sub-properties is not a concept in SHACL. If you use sub-properties, you will need to perform inferencing before you submit your data to the SHACL engine. That is, if you expect any validation to happen as a result of such declarations. People also often declare sub-properties only for the ease of query and not for inferencing. This way they could query, for example, for: ?p rdfs:subPropertyOf ex:parentProperty. ?s ?p ?o. As opposed to listing each individual property. Question about subclasses is, I believe, about inheritance or ways to re-use shapes. SHACL supports rdfs:subClassOf. In other words, if a target of shape X is class A, all direct members of A as well as indirect members (through A’s subclasses, transitively) are targeted. Purely SHACL option for re-use is to use logical expressions. For example: ex:Shape1 a sh:NodeShape; sh:property [sh:path ex:property1; sh:minCount 1]. ex:Shape2 a sh:NodeShape ; sh:and ( ex:Shape1 [ sh:path ex:property2 ; sh:minCount 1 ; ] ) . Of course, to make these shapes do anything, you would also need target declarations. With this, any target of Shape2 would also be validated against Shape1.
