Freshness
Also known as: Staleness
Freshness is how recently a record was updated. Stale data is the opposite - old enough that it may no longer reflect reality.
Freshness describes how current a piece of data is, usually expressed as a last-updated timestamp. Staleness is the inverse: data that has not been refreshed recently and may have drifted from the truth.
Freshness matters most for fast-moving facts. Star counts and maintenance status age quickly; a definition ages slowly.
In GraphCanon
Pages show when their facts were last synced, and structured data carries dates so both search engines and agents can weigh how current a claim is.
