The difference

How the difference is expressed.

The part

What it is

Absolute, percentage, or both. Percentages on small bases mislead and absolutes on large ones are hard to weigh.

Direction should be unambiguous: a rise is not always good, and colour conventions have to reflect that per measure.

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.
