Re: How looks ValidationReport + according ValidationResult for sh:or based shape?

Hi Konrad,

the spec uses a rather formal language to explain what is supposed to 
happen. In this particular case it states

if|v|conforms <https://www.w3.org/TR/shacl/#dfn-conforms>to none of 
themembers <https://www.w3.org/TR/shacl/#dfn-members>of|$or|there is 
avalidation result 
<https://www.w3.org/TR/shacl/#dfn-validation-results>with|v|as|sh:value|.

The test cases document

http://w3c.github.io/data-shapes/data-shapes-test-suite/#validate-rdf-data-tests

links to example(s) of what is supposed to be produced. This one here

https://github.com/w3c/data-shapes/blob/gh-pages/data-shapes-test-suite/tests/core/node/or-001.ttl

is close to what you seek, and produces

[
       rdf:type sh:ValidationReport ;
       sh:conforms "false"^^xsd:boolean ;
       sh:result [
           rdf:type sh:ValidationResult ;
           sh:focusNode ex:InvalidRectangle1 ;
           sh:resultSeverity sh:Violation ;
           sh:sourceConstraintComponent sh:OrConstraintComponent ;
           sh:sourceShape ex:RectangleWithArea ;
           sh:value ex:InvalidRectangle1 ;
         ] ;
       sh:result [
           rdf:type sh:ValidationResult ;
           sh:focusNode ex:InvalidRectangle2 ;
           sh:resultSeverity sh:Violation ;
           sh:sourceConstraintComponent sh:OrConstraintComponent ;
           sh:sourceShape ex:RectangleWithArea ;
           sh:value ex:InvalidRectangle2 ;
         ] ;
     ] ;

So, regardless of the structure of the sh:or, it will only ever produce 
a single sh:ValidationResult, and not any "nested" ones (although 
sh:detail could be used to record these, outside of the standard behavior).

If things remain unclear, please follow up. The example you mention 
below doesn't have a data graph, so it's difficult to answer.
