Clio Grows Up: From Research Prototype to Industrial Tool

Summary: Clio matures from research prototype to a tool for declarative XML/relational schema mappings. Mappings compile to an abstract query graph and emit XQuery, XSLT, SQL, or SQL/XML; architecture, algorithms, scalability, deployment lessons. (summarized by gpt-5-nano on Feb 09 2026)
