A posting from Jonathan Robie announces the availability of 'QuiP, a W3C XQuery Prototype'. QuiP is Software AG's prototype implementation of XQuery, the W3C XML query language. "QuiP can be used either with text-based XML files or for queries against a Tamino database. QuiP is designed to make it easy to learn and use the XQuery language." QuiP is available on Windows 32 bit platforms, and requires a Java virtual machine version 1.3; it may be downloaded for free.

IBM and Oracle Submit XQuery API for Java (XQJ) Java Specification Request. ...

Through collaborative and coordinated effort between W3C's XML Query Working Group and XSL Working Group, a collection of ten updated working draft specifications has been issued for public review and comment.

BumbleBee is an automated test harness for evaluating XQuery engines and validating queries expressed in the XQuery language. BumbleBee takes the pain and uncertainty out of learning and using XQuery. It starts by letting you immediately put several XQuery engines to the test so you know how they stack up against the XQuery specification. Then it lets you easily write your own tests to continually make sure your XQuery expressions produce reliable results when you upgrade your XQuery engine, try different engines, or otherwise make changes to your queries.

XQuery is the W3C's query language for XML. It is derived from Quilt, an earlier XML query language designed by Jonathan Robie together with IBM's Don Chamberlin, co-inventor of SQL, and Daniela Florescu, a well-known database researcher.

The World Wide Web Consortium has convened a working group to design a query language for Extensible Markup Language (XML) data sources. This new query language, called XQuery, is still evolving and has been described in a series of drafts published by the working group.

XQuery is still a relatively new and unfamiliar XML-based language, but it offers many possibilities for simplifying tasks that today are difficult or tedious. These five practical scenarios should give you ideas for leveraging XQuery in your own applications.

FLWOR = For, Let, Where, Order by, Return. This section explains the FLWOR method.

This document describes the namespace http://www.w3.org/2002/11/xquery-operators of the XQuery 1.0 and XPath 2.0 Functions and Operators specification (November 2002 version). XQuery is the query language produced by the W3C XML Query and XSLT working groups.

This chapter describes the syntax for queries written in the Liquid Data implementation of the XQuery language. The Liquid Data XQuery syntax is based on the syntax described in the December 2001 draft specification "XQuery 1.0: An XML Query Language" from the W3C:

This section provides XQuery reference information. It provides descriptions of the XQuery operator and functions available from the mapper. In addition, it provides reference information on the occurrence indicators, namespace prefixes, XML Schema data types used in the XQuery language.

This document describes Xquery-Lite 1.0 new features matching closer the Xquery 1.0 spec will be added to future versions of this language. New versions will always be compatible with older versions. This language may be extended but won't be changed.

XQuery and XPath 2.0 shares the same data model, functions, and syntax.

XQuery is about extracting information from XML documents.

This is a PHP implementation of the Xquery Lite language for XML query. This implementation is based on the PHP DOM extension (it uses Xpath). It is 100% compatible with Xquery Lite.

XQuery is an emerging W3C standard for querying XML, defined by the W3C XML Query Working Group. The latest XQuery publications from the W3C XML Query Working Group are at Working Draft status, so this standard is still evolving. Oracle is actively participating in the W3C XML Query Working Group.

As data integration continues to rise on the priority lists of most enterprise IT departments, startup Enosys Software has released an XML-based platform that promises a real-time view of disparate data sources.

XQuery maps provide a way for you to reshape the XML messages that web services send or receive. You use an XQuery map as a kind of translation layer between a web service method or callback and the outside world (its client, or a resource). Applying an XQuery map allows you to change the shape of a message dictated by the WSDL into the shape you want to use in your java program.

XQuery is a strongly typed, functional language, which supports the common processing, transformation, and querying tasks of a wide variety of XML applications. Following the tradition of other functional languages, XQuery includes a complete formal semantics. In this paper, we argue that basing an XQuery implementation on the XQuery Formal Semantics not only ensures correctness, but is a good foundation for optimization. We describe an architecture that we have implemented and that is based on the XQuery Formal Semantics and describe several logical and physical optimizations that can be easily integrated in the above architecture.
