  7. Model Graph: Model graphs in RACK are used to store the ontologies/semantic data models in the RACK database.

  8. Nodegroup: Nodegroups are .json files that represent connections between data and can be used to either query the RACK database or load instance data into the database.

  9. Ontology: Ontologies are semantic data models that represent the domain-specific relationships between the different types of data that are to be loaded into RACK.
