3) Inheritance of Application Annotation Axioms. Generally speaking, InPropertyGroup annotation axioms are not inherited by descendent properties. By contrast, InClassGroup annotations are inherited by descendent classes, and therefore do not need to be repeated. So if a descendent of a class previously defined as a referenced taxonomy root with a InClassGroup annotation is set as the range of another property (and thus made the root of a sub-referenced taxonomy), this root class does not need an additional InClassGroup Class Referenced Taxonomy axiom. But eagle-i referenced taxonomy IRI annotations are not inherited, so this descendent taxonomy root would still need an eagle-i Reference Taxonomy IRI annotation axiom pointing to the owl file where the root class lives.
