Deduplication by ISRC

ISRC is used as the dedup key. Multiple REC records with the same ISRC are merged into a single recording entry with multiple releases in releases[].

Records with no ISRC always create a new recording entry.

Relinquishment

The relinquishment object appears on a publisher participant when a PWR record signals that an original publisher (E) stops representing a writer for a specified scope. This is a CWR 2.2 Rev3 feature.

Field	Type	Req	Source Field	Description
`effectiveFrom`	string	M	`PWR.RelinquishmentEffectiveDate`	Date the relinquishment takes effect. Format: `YYYYMMDD`.
`postTermCollectionUntil`	string	O	`PWR.PostTermCollectionDate`	If provided, collection is still permitted until this date.
`scope.rightsTypes`	string[]	M	`PWR.RelinquishmentPR/MR/SR`	Rights relinquished: `["pr"]`, `["mr"]`, `["sr"]`, or combinations.
`scope.territories.include`	string[]	M	`PWR.RelinquishmentTerritoryCode`	TIS codes included (when `RelinquishmentTerritoryIndicator = "I"`)
`scope.territories.exclude`	string[]	M	`PWR.RelinquishmentTerritoryCode`	TIS codes excluded (when `RelinquishmentTerritoryIndicator = "E"`)
`note`	string	O	(generated)	Human-readable explanation

Trigger condition

Set when all three conditions are met on a PWR record:

RelinquishmentIndicator = "Y"
PublisherIPNumber resolves to a known publisher in publishersByIp
