The facts

The things the organisation needs to know.

The part

What it is

Customer count, revenue, headcount, order status, product configuration. A short list of things that matter, rather than every field in every system.

The ones that appear in reporting are the ones worth mapping.

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.
