OntologyResponderV1
^^^^^^^^^^^^^^^^^^^

The ontology responder provides information derived from all the ontologies in
the repository, including Knora ontologies as well as project-specific
ontologies. Most importantly, it provides information about resource classes
and properties. This includes the cardinalities defined on each resource
class, and takes into account the rules of cardinality inheritance, as
described in the section **OWL Cardinalities** in :ref:`knora-ontologies`.

For performance reasons, all ontology data is loaded and cached at application
startup. Currently, to refresh the cache, you must restart the application.
To maximise performance, the SPARQL queries used by the ontology responder
are very simple, and the responder calculates class hierarchies and cardinality
inheritance in Scala.
