I am trademarking right now YouML! The idea is to create a yahoo google interface implemented in j2. Features are building applications from any ML.

Sqeezing Andromda 3 into Jetspeed 2 will help this effort.

What is a MDA?

An engine that enterprets the Universal Modeling Language (UML) and exposes a java datamodel to meta facades and templates.

What are meta facades?

Objects generated from a UML model describing a framework such as struts, ojb, jsf portlet, xml schema with xmlbeans, data backup and restore with ddlutils, etc. The meta facades describe aspects of the framework such as it's capabilities to display complex web interfaces.

This is one of the grey areas of Andromda. The default Cartriges don't generate jsf or struts only. But rather an Andromda developers framework or best practice for using such technologies. Anyway what's interesting is that the framework is yours to choose. But the reality is you have to write or modify Cartriges to achieve your MDA generated framework.

What is an object model?

An object model is a java model view to the framework.

What is an Repository?

The Repository is the underlying UML implementation. Eclipse Modeling Framework and Netbeans UML implementation are two examples of Repositories.

Getting familiar?

So the contents of the repository is the bizness inteligence, or process modeled in UML.

What is all this about?

It's about working fast! No, that's not true!

It's about thinking graphically. Developing in a graphic environment. Building bug free boiler plate code. You code the logic if you want. Configuration is achieved in the meta facades and object models. The user works with UML objects by assigning them stereotypes and tagged values which determine the framework implementation. That's enough for now. Try it www.andromda.org
