iTrails: Pay-as-you-go Information Integration in Dataspaces

Summary: Introduces iTrails for pay-as-you-go information integration in dataspaces, adding lightweight declarative hints (trails) to gradually enrich loosely integrated data. Scalable rewriting and pruning support tens of thousands of trails with minimal query growth and improved query quality at low overhead. (summarized by gpt-5-nano on Feb 09 2026)
