Retention and deletion · The mechanism · Element

The copies

Where else the data exists.

The part

What it is

Backups, replicas, analytical stores, exports and local files. Deletion that covers only the primary system leaves most of the copies.

Backups are the standard difficulty and usually handled by a defined backup retention rather than by selective deletion.

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.
