The attempt

What was tried.

The part

What it is

The change, when it was made, and how long it ran before being reverted.

Including changes that were tested and never shipped, since those are the ones least likely to be remembered.

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.
