4 XQuery Reference

MonetDB/XQuery provides a full-fledged XQuery implementation, including support for updates (the XQuery Update Facility).

More details about the exact feature set that is supported in MonetDB/XQuery can be found here:

• XQuery Updates: MonetDB/XQuery supports the XQuery Update Facility (XQUF).
• Supported Functions: Overview of all supported Built-in Functions.
• Extension Functions: All supported Built-in Functions that are not part of the standard.

This documentation makes no attempt to teach you the XQuery language. For this we refer to tutorials on the web, and to the reference information provided by the W3C:

• W3C XQuery 1.0 now full standard recommendation.
• W3C XPath 2.0 the XML navigation sub-language, common to both XQuery and XSLT.
• W3C XQuery Functions and Operators provides an overview of all built-in functions.
• W3C XQuery Update Facility is a proposal in-the-works for updating XML documents (we still use the July 2006 version).

Additional W3C reference material:

• W3C XML Schema 2.0 note that schema support in MonetDB/XQuery is incomplete at this point.
• W3C XQuery Serialization defines how XML documents should be converted to text.
• W3C XQuery Formal Semantics formally defines the behavior of all XQuery language constructs.
