The retained rights
What each side keeps — data, IP, customers, and anything created jointly.
The part
What it is
Jointly created IP is the standard difficulty and should be settled at the start, when it is hypothetical and therefore easy.
Data is the other: what the partner holds, what they must return, and what they must destroy.
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.
