MonetDB/XQuery provides XML database functionality comprising quite complete support for the XQuery language, including modules, transaction-safe XQUF updates, user-defined functions, and a query cache (using XQuery modules). The system has very high performance and is scalable to large XML collections.
March 2011: MonetDB/XQuery project is frozen. Due to lack of development and manpower to port the software to MonetDB version 5, we had to freeze the code base.
