Hi Steve,
it SHOULD work, but TBC has two validation buttons and only the green
one includes the classes and properties:

I'm not understanding something about validating SHACL files. Normally
I successfully use shapes and SPARQLConstraints to validate rdf
instance files, but I'd also like to apply some constraints to our
SHACL shape definitions themselves.
For example, I'd like to ensure all our declared classes/Nodeshapes
have an rdfs:label, so I wrote:
owl:Class
sh:property [
sh:path rdfs:label ;
sh:minCount 1 ;
] ;
.
On the above, please double-check that owl:Class rdf:type sh:NodeShape
is also asserted.

I also tried
1. Writing a SPARQLConstraint to do the same thing.
2. Using the sh:targetClass method with an explicitly named shape.
3. Using these with sh:NodeShape instead of owl:Class, since all my
classes are also instances of sh:NodeShape.
None produced any validation errors when I ran the TBC validator on a
shapes file containing the definition of a class where I intentionally
omitted an rdfs:label value.
I know that the SHACL spec even has the shsh:ShapeShape specification,
so I assume this kind of thing can be done. Is something blocking the
validation error from showing up? Is it because rdfs:label is an
annotation property?
