vehicleType is a string. Why is its maxCardinality "nonNegativeInteger"?

NiclasScheiber commented 6 months ago

In OWL, max cardinality constraints just mean that the property cannot be present more than the indicated time. Hence it must be a non-negative integer.

The value of the property is not affected by this.

In this example, a TransportMeans may have 0 or 1 properties of type vehicleType (maxCardinality constraint) and that, if present, a vehicleType must hold an embedded object of type CodeListElement (allValuesFrom constraint).

The CodeListElement in turn can hold a code property (eg. "74F"), a description ("747 all Freighter models") and a codeListName ("IATA Aircraft Type Codes").
