Abstract
A metadata approach for retrieval from heterogeneous distributed XML documents is given. A prototype system uses distributed metadata to generate a GUI data integration tool, for describing mappings between master and local DTDs, by assigning index numbers and specifying conversion functions. A DDXMI (Distributed Document XML Metadata Interchange) file is generated based on the mappings, and used to translate queries over the virtual master document into sub-queries to local documents. Quilt is the XML query language. An experiment testing feasibility is reported using three bibliography documents. The system runs under NT, using Java servelets and JavaCC.
