Dataset IDs are permanent and immutable after publication.

An ID may never be changed.
A breaking schema change (incompatible column rename, type change) requires a new ID with a version suffix: rw.nisr.cpi.monthly.v2.
A dataset may be deprecated (set to pipeline: stale) but its ID is never removed from the catalog.
IDs always carry the country prefix. nisr.cpi.monthly is invalid; rw.nisr.cpi.monthly is correct.
