#apply_change_request(cr, removals: []) ⇒ Object

Applies a Parcel change request (CR) to this database.

cr is a Opencdd::Database whose entities represent the additions and updates to apply. removals: is an Array of IRDIs (Strings or Opencdd::IRDI instances) identifying entities to delete from this database.

Unlike #merge, which is purely additive, #apply_change_request honors an explicit removal list. The CR's own entities are upserted first (so an update-then-remove ordering resolves to remove), then removals are applied.

Returns self for chaining.

Raises:

  • (TypeError)
