Mia-Generation is a development environment to build custom generators based on a very powerful template mechanism.

Any kind of file (Java, C#, C, C++, Php, Xml, ...) can be produced by Mia-Generation from UML models.

It provides a dynamic bridge between analysis and design, and supports iterative cycles by preserving user defined code fragments between two generations.

The main features are :
* Full support of UML (1.3, 1.4, 2.0)
* Compliant with major modeling tools (Rose, RSM, MagicDraw, Rhapsody, Together, Poseidon, StarUML, and any XMI compliant tool).
* Full support of DSLs (expressed with MOF, eCore, DTD or XSD)
* Template based generation engine
* Java to customize templates
* Support for iterative development cycles (to preserve hand-written code)
* Built-in support for UML Profiles
* Dedicated development environment
* Facilities for generators deployment

Mia-Modernization is a customizable solution for modernizing J2EE legacy applications according to specific enterprise contexts :

* Retro-modeling : Java to UML transformations
* Refactoring : Java to Java transformations

Mia-Modernization can capture all the information contained within the Java or XML source files of any J2EE application (structure, variable definitions, statements, method invocations, ...) and provides a very powerful environment for defining transformation rules to apply on this information :

Altova Authentic is a FREE XML and database content editor that allows non-technical business users to view and edit data in XML documents and relational databases without being exposed to the underlying technology. They simply fill in electronic forms using the word-processor style WYSIWYG interface, and their content or query is automatically written to or run against an XML document or relational database behind the scenes.

Altova DiffDog is the developers dedicated differencing utility. This powerful, easy-to-use synchronization tool quickly compares and merges source code and text-based files and diverse directories via its straightforward visual interface. Uniquely, it also provides advanced XML-aware differencing and editing capabilities.

Altova MapForce Enterprise Edition is the premier data integration and Web services implementation tool. This award-winning, visual tool maps between any combination of XML, database, flat file, EDI, and/or Web service, then converts data on-the-fly or auto-generates program code for royalty-free use in your data integration or Web services applications. MapForce is the first and only product to let you choose between XSLT 1.0, XSLT 2.0, XQuery, Java, C++, or C# code generation from your data mapping designs.

OpenLaszlo is an open source platform for creating zero-install web applications with the user interface capabilities of desktop client software. OpenLaszlo programs are written in XML and JavaScript and transparently compiled to Flash and, with OpenLaszlo 4, DHTML. The OpenLaszlo APIs provide animation, layout, data binding, server communication, and declarative UI. An OpenLaszlo application can be as short as a single source file, or factored into multiple files that define reusable classes and libraries. OpenLaszlo is "write once, run everywhere." An OpenLaszlo application developed on one machine will run on all leading Web browsers on all leading desktop operating systems.

Pustefix is a framework that helps you to develop web based applications (referred to as projects here).

The framework consists of two more or less independent parts:
* A machinery to apply recursive XSLT transformations that produces the UI of the web application.
* A Java framework that takes input from the UI to change the application data and supplies changes of the application data back to the UI.

Together, the framework acts similar to the Model-View-Controller pattern (as far as this is possible in the context of a web application).
