The sample
What was collected, from where.
The part
What it is
A quarter of real output across every channel, including the ones nobody thinks of as brand material — invoices, notifications, job adverts.
Collected by someone who did not produce it, or the sample is curated before it is assessed.
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.
