The movable

What may change as the organisation does.

The part

What it is

Emphasis, examples, framing and which parts are told to whom. These should move, and saying so protects the fixed parts by giving change somewhere to go.

A narrative where nothing may move becomes false rather than stable.

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.
