Super Classes
The table below lists MeSH RDF super classes and their subclasses according to the MeSH RDF schema. Use inference when querying these super classes.
| Child Class | Predicate | Super Class |
|---|---|---|
| meshv:AllowedDescriptorQualifierPair | rdfs:subClassOf | meshv:DescriptorQualifierPair |
| meshv:DisallowedDescriptorQualifierPair | rdfs:subClassOf | meshv:DescriptorQualifierPair |
| meshv:GeographicalDescriptor | rdfs:subClassOf | meshv:Descriptor |
| meshv:TopicalDescriptor | rdfs:subClassOf | meshv:Descriptor |
| meshv:PublicationType | rdfs:subClassOf | meshv:Descriptor |
| meshv:CheckTag | rdfs:subClassOf | meshv:Descriptor |
| meshv:SCR_Chemical | rdfs:subClassOf | meshv:SupplementaryConceptRecord |
| meshv:SCR_Disease | rdfs:subClassOf | meshv:SupplementaryConceptRecord |
| meshv:SCR_Protocol | rdfs:subClassOf | meshv:SupplementaryConceptRecord |
An example where inference is required would be to query all instances of subclasses of meshv:Descriptor (meshv:TopicalDescriptor, meshv:GeographicDescriptor, etc).
