8 - Traversing the Ontology

📖 Task Introduction

Let’s now retrieve the average departure delay for all flights along this route to help us better understand how divergent our delay is. To do this, we’ll need to cross additional links in the Ontology via the [Example Data] Route object type.

🔨 Task Instructions

1. Click into your Linked Flights card and then on the Objects category button along the bottom of the card.

2. Click Linked object set.

3. In the editor panel, choose [Example Data] Route in the Select Relation Type field.

4. Change the name of your new card from the default (e.g., [Example Data] Routes linked to [Example Data] Flights) to Linked Route.

   • We’ll now need to bring back all flights linked to this route and then any delays linked to those routes.

5. At the bottom of the Linked Route card click the Objects category and choose Linked object set.

6. In the editor panel, choose [Example Data] Flight in the Select Relation Type field.

7. Change the name of your new card from the default (e.g., [Example Data] Flights linked to [Example Data] Routes) to Route Flights.

8. Using the Objects → Linked object set click path used in the steps above, create a new card that represents all [Example Data] Delay objects linked to your Route Flights object set.

9. Change the name of your new card from the default (e.g., [Example Data] Delays linked to [Example Data] Flights) to Route Delays.
