The historical

What happens to the data already collected wrongly.

The part

What it is

Corrected, flagged, or left with a note about the date the fix took effect. All three are defensible and the choice should be recorded.

A fix with no treatment of history produces a discontinuity that looks like a business change.

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.
