Description

In an application schema, cardinality specifies the number of instances of a property that may be associated with a single instance of a feature type. The following figure shows how cardinality is represented in a UML class diagram.

cardinality

In RDF, OWL restrictions can be used to specify the cardinality of a property.

We are not aware of use cases involving INSPIRE data represented in RDF that would require the validation of cardinality constraints. Therefore we propose to not encode the cardinality of properties in INSPIRE RDF schemas.
