* - The constant knora-api v2 ontologies that are defined in Scala rather than in the triplestore, [[KnoraBaseToApiV2SimpleTransformationRules]] and [[KnoraBaseToApiV2ComplexTransformationRules]].
*
* It maintains an in-memory cache of all ontology data. This cache can be refreshed by sending a [[LoadOntologiesRequestV2]].
*
* Read requests to the ontology responder may contain internal or external IRIs as needed. Response messages from the
* ontology responder will contain internal IRIs and definitions, unless a constant API v2 ontology was requested,
* in which case the response will be in the requested API v2 schema.
*
* In API v2, the ontology responder can also create and update ontologies. Update requests must contain
* [[ApiV2Complex]] IRIs and definitions.
*
* The API v1 ontology responder, which is read-only, delegates most of its work to this responder.
