摘要：

MetaXQuery is a language for querying data enhanced with metadata. The MetaXQuery data model (MetaDOM) attaches metadata to each element in an XML data collection, and extends XQuery with several constructs to process and query metadata. In this paper we show how to extend a native XML DBMS, namely eXist, to support MetaXQuery. The additional query functionality can be efficiently implemented by judicious reuse of eXist's indexes and query evaluation engine.
