Term	Kind	Topic	What it is
Data Product Published Dataset, Owned Data Asset, Analytical Interface	concept	Data Products	A dataset published deliberately as an interface with a named owner, documented semantics, quality guarantees and a change policy - as distinct from a table that consumers happen to be able to reach.
Data Product	concept	Data Products	A curated, documented, owned dataset treated as a product with consumers, a service level and a lifecycle, rather than as the output of a pipeline.
Dataset Deprecation Policy Dataset Sunset Policy, Retirement Notice Period	practice	Data Products	The written rule stating how a published dataset or column is retired - the notice period, how consumers are identified, and what happens if they do not move - without which nothing can ever be removed.
Partition Immutability Promise Closed Partition Guarantee, Correction-Row Policy	pattern	Data Products	A published commitment that once a time partition is closed its rows will never change, with corrections issued as new rows - so consumers can checkpoint and reconcile instead of reloading history.
