Reverse Data Exchange: Coping with Nulls
Summary: Homomorphism-based reverse data exchange supporting source labeled nulls via extended identity/inverse and max extended recovery. Proves existence and shows max extended recoveries quantify TGDs' info loss, enabling reverse exchange and query answering. (summarized by gpt-5-mini on Feb 09 2026)
