The verb
What the organisation does, as an ordinary verb.
The part
What it is
Build, run, sell, teach, repair, publish, transport. Concrete verbs are available for almost every organisation and are almost never used.
Where no concrete verb fits, the organisation usually does several things and the mission is trying to cover 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.
