Certain Answers for XML Queries
Summary: Model-theoretic extension of certain-answer semantics to XML tree-producing queries with general computability and complexity results. Introduces a basis-of-trees method to compute certain answers for pattern queries over nulls and data-exchange documents, and pinpoints a natural class of XML mappings that admit efficient query answering and static analysis.
