Error List for the domain-specific verification
The following errors are generated during the compliance check of a schema.org annotation/RDF-Graph based on the constraints defined by a Domain Specification.

Semantics for Class Matching
In the following our understanding of the class-subclass relationship is explained.This relationship is important to determine valid matches for sh:targetClass / sh:class and ds:subDSOf.
A set of classes 'SubDS' is a valid match for another set of classes 'SuperDS' if all elements in 'SuperDS' are also present in a set that contains all elements from 'SubDS' along with all their superclasses:
classes(SuperDS) ⊆ superclasses(classes(SubDS))
The following table gives examples for this.
