# Abstract Classification Classes
#
# OWL classes representing ArchiMate 4.0 metamodel categories by
# aspect (BehaviorElement, ActiveStructureElement, etc.) and
# domain (CommonDomainElement, BusinessDomainElement, etc.).
# Concrete elements use rdfs:subClassOf to inherit from both
# their aspect and domain classes. SHACL shapes use
# rdf:type/rdfs:subClassOf* to query the hierarchy.
#
# In ArchiMate 4.0, the "Hexagonion" replaces the 3.x layer
# hierarchy with a domain-based organization. Behavior elements
# are no longer split per layer — Process, Function, Event, and
# Service are single cross-domain concepts in the Common Domain.
