A.6.3:4.1 - Identify both epistemes independently
Before declaring a viewing, recover for each of X and Y under C.2.1:
- exact claim content;
- exact EntityOfConcern;
- effective
U.ReferenceScheme.
X and Y are separate epistemes whenever one of those identity discriminators differs. A filename, table, diagram, query result, viewpointRef, or publication form is not a substitute for either identity.
If the supposed receiving item has no recoverable claim content or EntityOfConcern, stop: the receiving episteme has not been identified. If the exact EntityOfConcern differs, use A.6.4 retargeting rather than A.6.3.
