Choosing what to measure · The chosen set · Element
The cap
The maximum number, and how additions are handled.

What it is
A hard cap forces a trade every time someone proposes a new measure, which is the conversation that should happen.
Where the cap is exceeded, the set has been expanded without anyone deciding to.
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.
