The path

Which sequence determines the date.

The part

What it is

The longest chain of dependent items including the waiting, which is what most schedules omit.

Frequently shorter in work and longer in elapsed time than people expect, because it is dominated by external items.

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.
