# FHIR core — TRUE subset of HL7 FHIR R4 resource-type vocabulary.
# Upstream: http://hl7.org/fhir/R4/   License: see HL7 terms
#
# This file ships ONLY the resource class hierarchy. The published
# HL7 FHIR RDF ontology (http://hl7.org/fhir/fhir.ttl) uses a rich
# value-type metamodel (fhir:link, fhir:CodeableConcept, fhir:Reference,
# wrapped scalar values, etc.) — flattening Patient.subject, Observation.code
# etc. into bare OWL properties with rdfs:range xsd:string would NOT be a
# subset of FHIR-RDF; it would contradict it. So we omit those axioms.
#
# If you need full FHIR data modeling, load HL7's published RDF ontology
# directly (predicate init --mode upload --file fhir.ttl).
