The observations

What actually happened.

The part

What it is

Where they hesitated, what they tried first, what they said out loud, and where they gave up.

Recorded as behaviour rather than as interpretation, since the interpretation can be argued with later and the behaviour cannot.

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.
