How to create objects in foundry?

Recently started working on palantir's foundry. The documentation is poor, unable to figure out how to create objects at the first place.

I was able to create an object type, however poorly configured, how do I use the objects from it in the object viewer

1. Create an object type in the Ontology Manager app. Sounds like you've done this. Great!
2. Pick a backing dataset for that object type in the Ontology Manager app. Each row in this dataset should have a unique value for its primary key column, and each row should correspond to a single object.
3. When the dataset has been indexed into the ontology -- which will start automatically when you save your object type with a backing dataset -- you'll be able to use the Object Explorer app to view each object. The default view for an object type in Object Explorer is pretty spartan -- just some properties and any links to other objects -- but you can configure it to include other widgets and data.

If you don't have a backing dataset, you can use an empty dataset with just a schema (header row, essentially) and create an Action to create objects. Then you can call that action via its API endpoint or use it in an Object View, a Workshop app, etc. to create individual objects.
