Describing and Using Query Capabilities of Heterogeneous Sources

Summary: Introduces two languages for describing query capabilities of heterogeneous sources and compares their expressive power. Presents matching/translation algorithms to map queries to source-specific forms and improved query answering using these descriptions. (summarized by gpt-5-nano on Feb 09 2026)
