Computer scientists of the Centrum voor Wiskunde en Informatica (CWI) in Amsterdam and the Universities of Twente and Konstanz will launch MonetDB/XQuery at the Holland Open Software Conference in Amsterdam (May 30 - June 1). Storing and querying high volumes of XML data require new software systems. MonetDB/XQuery is an open source system that provides a complete implementation of XQuery. This makes it possible to search both the content and structure of large XML documents.
MonetDB/XQuery is built on the MonetDB Relational Database Management System developed by CWI. The new system performs better than any other XQuery-system known today, both in query performance and in size of the queried documents. This was measured with the international XMark benchmark. The new XQuery processor is developed as an open source project. It can be used on a large number of hardware and software platforms - such as Windows and Linux - for scientific, commercial and private purposes. The research has been done in the Pathfinder project in the BSIK research programme MultimediaN.
