Data sets whose owner has left.
The part
What it is
Found by comparing the ownership register against the current staff list, which takes minutes and is rarely done.
Each is a data set nobody is maintaining, usually without anyone having noticed.

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.
