Representation sufficiency is investigated by specifying distinctions to preserve and permitted collapses. Unless a stronger result is established, sufficiency is inquiry-relative.
The Autorite series follows this idea through distinctions between present state, realized history and specified prediction tasks.
This connects to
Memory
A memory form can be examined through the historical distinctions it represents.
Context
Representation sufficiency depends on the inquiry or action it serves.
History
Which distinctions in realized history must survive is a representation question.
Preservation
A representation can be assessed by whether it preserves chosen distinctions.
Relation
Relational information can be among the distinctions a representation must preserve.
Photography
Framing chooses the boundary between what is visible and what remains outside.
