The versions
Each version of the position, with its dates.
The part
What it is
Superseded versions kept rather than overwritten, so that the history is readable.
How long each held is the most useful field, because it shows whether the organisation is capable of holding a position at all.
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.
