Thx, for the way back I guess using sh:values? (at someotherclass)

For inferencing, I would associate a rule with :SomeOtherClass to infer 
membership in :ExampleClass (made up name since you did not give one) if the 
hasValue condition is met.

It is similar to the below example where type Square is inferred for a 
rectangle with the same width and height.

ex:Rectangle a rdfs:Class, sh:NodeShape ;
rdfs:label "Rectangle" ;
sh:property  [ sh:path ex:height ;
  sh:datatype xsd:integer ;
  sh:maxCount 1 ;
  sh:minCount 1 ;
  sh:name "height" ; ] ;
sh:property [ sh:path ex:width ;
  sh:datatype xsd:integer ;
  sh:maxCount 1 ;
  sh:minCount 1 ;
  sh:name "width" ; ] ;
sh:rule [ a sh:TripleRule ;
  sh:subject sh:this ;
                sh:predicate rdf:type ;
  sh:object ex:Square ;
  sh:condition [ sh:property [ sh:path ex:width ; sh:equals ex:height ; ] ; ] ; 
] .


Of course, you would use sh:hasValue instead of sh:equals.

For constraint checking, you need to have the following for :ExampleClass

hasValue :v1 constraint for :p1 path and
hasValue  :SomeOtherClass constraint for rdf:type/rdfs:subClassOf* path.

Having an owl-rl restriction like:

  owl:equivalentClass [
      rdf:type owl:Class ;
      owl:intersectionOf (

            rdf:type owl:Restriction ;
            owl:hasValue :v1 ;
            owl:onProperty :p1 ;
          ]

How would that best translate to SHACL? (under an inference assumption, not 
just checking).

Should I use SHACL-AF sparql construct for each direction?
Or can I reuse some AF syntactic sugar construct in one or both directions?

Thx Michel
