✅ What you built

  • An Ontology Project: Flight Alerts project (a "folder" in this case) composed of recommended folders and artifacts.
  • An ontology_flight_alerts_logic batch pipeline that applies final transform steps to prepare your three datasets for synchronization to the Ontology.
  • Updated flight alert and passengers schedules that now treat your Ontology datasets as the build targets.
  • Updated health checks on the new schedule targets.

✅ What you learned

  • You can consult the documentation to ramp up on functional Solution Design in Foundry.
  • Schema recommendations for Ontology datasets are available in the Foundry documentation.
  • Object types are backed by a single dataset, and a dataset can back only one object type.
  • Many-to-Many link types in the Ontology must be backed by a join table.
  • Datasets that will be used to back Ontology object and link types should be output by a code repository into an Ontology Project.
  • You should always have an intermediate transform step from clean to ontology datasets, even if it seems like an unnecessary formality.
