W3C Invites Implementations of XQuery 3.1: An XML Query Language

Author(s) and publish date


The XML Query Working Group invites implementation of the Candidate Recommendation of XQuery 3.1: An XML Query Language. XML is a versatile markup language, capable of labeling the information content of diverse data sources including structured and semi-structured documents, relational databases, and object repositories. A query language that uses the structure of XML intelligently can express queries across all these kinds of data, whether physically stored in XML or viewed as XML via middleware. This specification describes a query language called XQuery, which is designed to be broadly applicable across many types of XML data sources.
