The stated purpose
What the data was collected to do.
The part
What it is
Specific enough to exclude something. “To improve our services” excludes nothing and is therefore not a purpose.
It should match what people were actually told rather than what the organisation intended.
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.
