Qizx is an embeddable, high-speed, native XML
indexing and query engine written in Java(TM),
with the querying and processing capabilities of a
fully fledged XML Query implementation.
What is new in version 3.0
This version mainly fixes bugs found in 3.0 beta:
* A bug appearing when many threads perform
transactions simultaneously. This is unlikely to
happen in normal use, but can compromise the
integrity of an XML Library (database).
* Two memory leaks
* Improved database integrity checks and recovery.
New features in 3.0 with respect to 2.2 are:
* Efficient and nearly complete support of
XQuery Full-Text, a new W3C Recommendation for
integrated full-text search in XQuery.
* Miscellaneous optimizations of query execution.
The former version 2.2 is no more available.
We strongly recommend to upgrade to Qizx 3.0.

for more information.
Qizx is available in several editions:
* The commercial product has 3 liberal licenses
both for corporate application development, and
for royalty-free distributable products.
* The Free Engine edition is a fully functional
version of Qizx which can be used for developing
or in production. It is limited in database
size (one gigabyte of XML approximately).
* Qizx/open is an open-source version of the XML
Query interpreter of Qizx. Qizx/open has been
available since 2003 and is recognized as one
of the most advanced and fastest XML Query
implementations.
Qizx Free Engine can be downloaded from
