The accessibility

Whether the evidence can actually be produced when asked for.

The part

What it is

Evidence held in a system nobody can query, or by a person who has left, is evidence in principle only.

The practical test is whether a sample can be produced within a day, which is roughly what an inspection allows.

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.

Which system or location.

Retrieval time
How long to produce a sample, which is the practical test.
