The group

Who is served, in terms that exclude someone.

The part

What it is

Specific by size, sector, situation or role. The test is whether a reader could tell they were not in it.

Where several groups are served, naming the primary one is more useful than listing all of them.

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.
