This paper describes a metadata interchange approach for semi-automated integration of heterogeneous distributed databases. Our system prototype uses distributed metadata to generate a GUI tool for a meta-user (who does the metadata integration) to describe mappings between master and local databases by assigning index numbers and specifying conversion function names; the system uses Quilt as its XML query language. A DDXMI (for Distributed Database XML Metadata Interface) file is generated based on the mappings, and is used to translate queries over the virtual master database into sub-queries to local databases. An experiment testing feasibility is reported in which 3 different bibliography databases are integrated.
