85% of the SNOMED relationships are isa. The rest come from the around 50 non-isa relationships in @@. As SNOMED was not trying to capture (model) computable properties, these isa relationships map to:
- rdfs:subClassOf
- rdfs:subPropertyOf
- rdf:type
- owl:equivalentClass
- owl:oneOf
- owl:unionOf
JohnM usually expresses isa as the semantically neutral snomed:isa in an inferencing system like Sesame. He chooses at data consumption time whether to add one of:
- snomed:isa rdfs:subPropertyOf skos:broader .
- snomed:isa rdfs:subPropertyOf rdfs:subClassOf .
and leverage the ensuing inferences.
Peter Hendler (Kaiser Permanente) had modeled SNOMED in OWL.
