About the RDA Registry and vocabularies
Representing the RDA ontology
Datatype and object element sets
The RDA Vocabularies provide OWL datatype and object properties based on the RDA "canonical" properties. A datatype property can be used with or without a syntax encoding scheme for a value from one of the literal paths; an object property can be used for the URI.
Each datatype and object property is linked to its canonical property by an RDFS sub-property relationship.
The URI of each datatype and object property is derived from the URI of its canonical property by extending the namespace and retaining the most local part.

Each datatype and object property has the same domain as its canonical property.
Each datatype and object property has the same label and lexical alias as its canonical property.
There are no definitions or scope notes for a datatype or object property. The human-readable semantics are associated with the canonical property.
Machine-readable semantics are expressed with object properties. The object property element sets contain, in particular:
- representation of reciprocal RDA elements using the OWL inverse property.
- representation of the target entity of RDA relationship elements using the RDFS range property.
