The fields

What is recorded with each event.

The part

What it is

The fields determine what questions can be answered. An event with no context fields records that something happened and nothing about it.

Consistency of field names across events is what allows analysis to join them.

The smallest level

The attributes it carries

Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
