The XQuery Development Toolkit (XQDT) is a proposed project under the Web Tools Project.

According to the Eclipse Development Process, this proposal is intended to declare the intent and scope of the XQuery Development Toolkit project as well as to gather input from the Eclipse community. You are invited to comment on and/or join the project.


XQuery was designed by XML Query working group of the W3C in order to present a convenient way to query largely (but not limited to) XML data collections and became a W3C recommendation on January 23, 2007. Currently many commercial XML Databases support XQuery as a platform to query its data. Also with the upcoming new XQuery version which is 1.1, it is believed XQuery will be the main data query technique for XML documents as well as databases. As such, it is quite useful to have an editor for XQuery with rich functionality such as syntax validation and content assistance under WTP umbrella.


XQuery Development Toolkit(XQDT) is mainly an editor built on Structured Source Editor(SSE) for easy XQuery handling. It will initially have basic text editor functions such as syntax colouring and content assistance to create and modify XQuery documents easily. Later it could be added more rich features such as content formatting, advance preferences, error tips and support to other commercial XML databases through extension points.

Project Description

XQuery Development Toolkit project will be based on the project done by Buddhika Laknath for Summer of Code 2008 named "New Eclipse Plugin for XQuery" mentored by David Carver who is a committer for XSL Tools. The initial idea of the project is to fill gaps in Eclipse in regards to new XML formats and persuade more web and XML users to choose Eclipse as their native platform.


Basic goal of the project is to provide a rich text editor for XQuery developments with Eclipse. Other than that, it's our hope that this will be an incentive to draw more attention from XML users into accepting Eclipse as their main development platform.


Currently Scope is limited to providing basic text editing features for XQuery language based on Structured Source Editing components. But at the end of first phase, providing that users requesting more features into the editor, it will be moving forward to bring more rich text editing experience to users.

As always, scope can change based on community and adopter feedback as well as changes in XQuery standards.


Perspectives and Views

Extension Points

Project Organization

We propose this project should be undertaken as an incubator project with the Web Tools project.


Need WTP Mentors.


  • Budhikka Laknath - Contribution/Committer - Budhikka wrote the initial code during the Google Summer of Code Project.
  • David Carver (XSL Tooling Committer)

Initial Code Contribution

The initial code contribution comes from the Summer of Code 2008 project which is hosted at sourceforge, XQuery Plugin

Licensing and Intellectual property

All code is being relicensed under the terms of the Eclipse Public License. All committers have agreed to these relicensing terms.

Interested Parties

User community

XQuery already has a large user community that covers both the data side of xml as well as the document centric side of the XML. It is becoming the defacto standard for querying XML repositories and data bases, and is a good complement to other XML technologies like XSL. As more traditional database add support for XML databases having a good base set of XQuery tools to use and extend will become increasing important.
