Temporal validity
thecontinuitylayer.com/glossary/temporal-validityThe definition
The span during which a fact was true, as distinct from when the system recorded it. A record with temporal validity can retire a stale value when a newer one contradicts it, and can answer both “what is true now” and “what was true then”. See Bi-temporal memory.
The same words the glossary hub and the public data mirror carry; this page is the stable address for the term.
