{{Short description|XUF is Xquery Update Facility, an extension to XML Query Language}}
{{notability|date=September 2011}}
XQuery Update Facility is an extension to the XML Query language, XQuery. It provides expressions that can be used to make changes to instances of the XQuery 1.0 and XPath 2.0 Data Model.
It became a W3C Candidate Recommendation on 31 July 2009 and was finalised as Recommendation on 17 March 2011.{{cite web|url=http://www.dblab.ntua.gr/~bikakis/XML%20and%20Semantic%20Web%20W3C%20Standards%20Timeline-History.pdf |title=XML and Semantic Web W3C Standards Timeline

A version to work with XQuery 3.0 was drafted,[https://www.w3.org/TR/2017/NOTE-xquery-update-30-20170124/ XQuery Update Facility 3.0] but was never completed, and is archived as a W3C Working Group Note.
