The awareness
Whether people know the route exists.

What it is
A route nobody knows about is not a route. Asked directly, most people in most organisations cannot say who to tell.
Repeating it periodically costs nothing and is what keeps it usable.
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.
