PEMF is Valis' audience model for information access. It defines who content or a database is meant to be visible to in principle, across four tiers: Public, Employees, Management, or Founders.
The tiers, ordered from broadest to most restricted:
- Public — open access, visible to anyone.
- Employees — internal team only.
- Management — management-level restriction.
- Founders — founder-only, highest restriction.
PEMF is used operationally to tag databases and documentation with their intended audience via the VEC (View / Edit / Comment people-properties) property. It is also used as the color axis in the , where each PEMF tier maps to a distinct color (Green, Orange, Red, Blue respectively).
