Project Example

This example illustrates a transformation operator informally.

It is not a formal definition and does not decide persistence.

Operator

PR  project

Intuition

A project transformation derives a selected view or representation from a referent.

Formal authority

The authoritative operator definition is in:

SETheoryTransformation/Domain/Operator/Codes.lean
SETheoryTransformation/Domain/Operator/Labels.lean
SETheoryTransformation/Domain/Operator/Semantics.lean

The reference mirror is in:

reference/transformation-operators.toml

Boundary

Project describes selected representation.
Persistence is evaluated downstream.
