CookXml is a powerful dynamic XML data binding tool for Java. It is designed to be easily extensible and yet simple to use, with advanced exception handling. CookSwing and CookSwt are tag libraries for CookXml to do XML->GUI (XUL) for Swing and SWT.

HSPL is Human Speakable Programming Language, allowing for communication between human-to-computer and human-to-human in the same language. This project has moved to http://sourceforge.net/p/spel We are currently working on human-to-computer programming-language with mostly English base vocabulary. Though once we have that, we plan to add support for other world Languages, including Chinese, Spanish, Russian, Arabic, Hindi, among others. Eventually HSPL shall be the foundation of GIOS the General Intelligence Operating System. Which is an open source operating system, that can be used for intelligent robots, computers and technological host-bodies. Regularly post on blog about HSPL at http://weyounet.info/?s=hspl

IXML (short for "Interface XML") is a Java framework to create Swing user interfaces using XML files that describe the UI.

This project is now abandoned in favour of MorganaXProc-III which implements XProc 3.0: https://sourceforge.net/projects/morganaxproc-iiise/ MorganaXProc is a full implementation of XProc: An XML Pipeline Language (W3C Recommendation 11 May 2010) written in Java, supporting all required and optional steps, the steps proposed on EXProc.org and also the document templating steps "p:in-scope-names" and "p:template". XPath 2.0 or XPath 3.0 is used as expression language. XSLT and XQuery are supported out of the box, while a flexible connector mechanism also allows to employ your favorite XSLT and XQuery processors. The current version is 1.0.x. It is very close to the recommendation with all related tests of the XProc Test Suite passed.
