The use

What the output is used for.

The part

What it is

Deciding where the next increment of budget goes is a good use. Judging a channel’s worth in isolation is not.

Attribution used as a performance report mainly settles internal arguments and settles them in favour of whoever owns the trackable channels.

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.
