eXist is an open source database management system entirely built on XML technology, also called a native XML database. Unlike most relational database management systems, eXist uses XQuery, which is a W3C Recommendation, to manipulate its data.

Contents

eXist allows software developers to persist XML data without writing extensive middleware. eXist follows and extends many W3C XML standards such as XQuery. eXist also supports REST interfaces for interfacing with AJAX-type web forms. Applications such as XForms may save their data by using just a few lines of code.

eXist has support for the following standards and technologies

  • XPath - XML Path language
  • XQuery - XML Query langage
  • WebDAV - Web distributed authoring and versioning
  • REST - Representational state transfer (URL encoding)
  • SOAP - Simple Object Access Protocol
  • XACML - XML Access Control Language
  • XInclude - server-side include file processing (limited support)

eXist was created in 2000 by Wolfgang Meier who still is the lead developer as of 2007. In September 2006, it reached version 1.0 and 1.1 (new numbering scheme). Current development activities are on the 1.1.x versions.
