Where to start

Inspect the dataset structure and metadata before modifying or combining episodes.

Use it in your project

Write a schema audit for one episode, including observations, actions, time and provenance.

Scope and limitations

Dataset versions differ. Do not assume that examples for one format apply unchanged to another.
