The drivers
Why the shape exists.
The part
What it is
Weather, budget cycles, school terms, regulatory dates or the customers’ own seasonality. Knowing which matters, because different drivers move differently.
A shape driven by customer budget cycles is stable; one driven by weather is not.
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.
