The provisional

What is planned but changeable.

The part

What it is

A quarter is typical. Subjects are named and slots are allocated, but either can move without disruption.

This is where seasonal moments are placed early enough to be prepared.

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.
