The date
When the project ended.
The part
What it is
A stated date, which is what the estimate is compared against and what releases the capacity.
Without it, the project’s duration is unknowable and the estimate cannot be 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.
