  Data Models are structured representations of entities, attributes, and
  relationships that define how data is stored, accessed, and exchanged.
  The landscape spans relational, hierarchical, network, object, document,
  graph, key-value, columnar, and event-sourced models, plus shared
  semantic models like Schema.org, FIBO, FHIR, ISO 20022, and W3C RDF/OWL.
