Abstract

A standard query language is very helpful for interoperability among digital library systems over the Internet. We propose an XQuery engine that can be used as an XQuery processing module in a digital library system that supports XML documents. We assume generic digital library system architecture. It consists of four modules: a user interface, an XQuery engine, an information retrieval engine, and an XML repository. The XQuery engine parses an input XQuery and constructs a syntax tree for the query.
