Translating Web Data

Summary: Clio translates high-level correspondences between heterogeneous relational/XML schemas into complete, constraint-aware source queries. It uniquely preserves independent source/target semantics, hierarchy, and nested referential constraints, even inventing required non-null target values. (summarized by gpt-5.6-luna on Jul 24 2026)
