XDBM is an XQuery implementation on the W3C's EXI binary XML format.
XDBM version 2 will be an XQuery implementation that uses EXIP to handle binary XML in the EXI format adopted by the W3C. It will, like EXIP, aim to be as small as possible so that it runs well on resource constrained devices. It is still in the project design stage.
Xcerpt is a Query and Transformation Language for XML and Semistructured data. Instead of the navigational approach of XPath-based languages like XSLT or XQuery, Xcerpt uses patterns for querying and is based on concepts of logic programming like unifica
LOTS is a web-based, fully integrated E-learning system. It is a complete solution to accomplish multiple online courses covering thousands of students. As a specialty it contains SQL and XQuery training modules including tutorials and example databases.
MXQuery is a low-footprint implementation of XQuery 1.0, XQuery Update 1.0, XQuery Fulltext 1.0 and XQuery Scripting 1.0 as well as a subset of XQuery 1.1 (windowing, try/catch). It provides extensions to do data stream processing/CEP and SOAP/REST
XPN is relies on a non relational native XML database, where XML documents are stored in a compressed form and indices enables fast access to structure and content, thus enabling a fast evaluation of XQuery queries.
BaseX is a light-weight, high-performance and scalable XML database system and XPath/XQuery processor, including full support for the W3C Update and Full Text extensions. The issue tracker has been moved to https://github.com/BaseXdb/basex/issues
The goal of the XQC project is to create standardized C/C++ APIs for interfacing with XQuery processors. They should provide mechanisms to compile and execute XQueries, manage contexts, and provide a basic interface for the XQuery Data Model.
The Semantic Web implementation using native xml database as backend storage. A SPARQL java compiler to XQuery using Jena. There are XQuery scripts for native xml database Sedna(http://modis.ispras.ru/sedna/).
XAnswer project is aimed to coordinate efforts in development of different components of XQuery processing engines by means of "standard" API, specifications and protocols.
PHP & Perl classes to query eXist XML:DB.
A set of classes, implemented in both PHP and Perl, that allows to query the XML:DB using the XQuery language.
Connection with eXist is done through a SOAP interface, using a WSDL defintion.
The IPSI XQuery Demonstrator (IPSI-XQ) is a prototype of an XQuery engine. It implementes as faithfully as possible along the current W3C working drafts.
Mod_dbxml integrates the Oracle Berkeley DB XML native XML database with the Apache Web server. Create dynamic Web content by direct XQuery database access.
Abacus Technologies Relational XQuery is an XQJ compatible XQuery processor that provides the ability to execute XQuery against both relational and XML data sources. Relational data can be transformed to any XML schema using XQuery's powerful features.
XQEngine is a Java component for searching collections of XML documents that uses an XQuery front end. The engine has a straightforward API that allows it to be easily embedded in end user applications. Requires some basic Java programming skills.
XQDB is a XML-XQuery-Database Management System. Based on PHP and a relational database (SQL). The treestructur is saved by the nestedset-technology. XQDBMS is supporting XPath- and XQuery-expressions.
