E.10.D2:8.1 - Describing use, viewpoint, and view
For one named describing use, state that the use selects one exact U.Viewpoint episteme P when that selection changes what is read or checked. It says from which concern-bearing viewpoint the already identified episteme is being read for that use.
That selection:
- does not acquire C.2.1 episteme identity;
- does not establish
EpistemeViewpointConformanceRelation; - does not admit or remove same-individual
U.Viewmembership; - selects no receiving view and performs no A.6.3 viewing construction;
- may change between two describing uses while the episteme remains unchanged.
Call the same episteme a U.View only when it conforms to at least one exact U.Viewpoint episteme under E.17.0’s fixed membership rule. Direct authoring and A.6.3 source-to-receiving construction can produce an episteme but grant no view membership. A rendering, publication form, or carrier-borne display is not a view by appearance. If one use selects several viewpoints, keep each identified. Use C.13 only when that use depends on the plurality as a collection and A.22 only when it depends on their organization; do not overload one context qualification.
