The origin

When the format started, and why.

The part

What it is

A format nobody can date is being produced out of momentum. That is not an argument for stopping it, but it is an argument for asking.

Origins are often a person rather than a decision — someone who liked making it and has since left.

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.
