## Defining cardinality of properties

By default, properties are multivalued, there are no restrictions in the number of values a property can store.

    <xi:include></xi:include>

Wherever this is not desirable, cardinality can be limited on properties through nrl:maxCardinality.

    <xi:include></xi:include>

This will raise an error if the SPARQL updates in the endpoint end up in the property inserted multiple times.

    <xi:include></xi:include>

Tracker does not implement support for other maximum cardinalities than 1.
