Composition of Mappings Given by Embedded Dependencies

Summary: Gives algorithms and sufficient conditions for composing mappings specified by embedded, full, or Skolemized SO dependencies (beyond source→target). Shows limits: full deps not closed, non‑source→target SO deps fail closure under restricted composition, and deciding expressibility is undecidable. (summarized by gpt-5-mini on Feb 09 2026)
