The accuracy
Whether the values are right.
The part
What it is
Checked by sampling against something external — a phone call, a document, an observation. Internal consistency is not accuracy.
A small sample is enough to establish an error rate, which is what is actually needed.
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.
