MDE / MDA / MDSD / etc.

OMG has defined the MDA term.

But now, what a jungle !
Let's see some very simple definitions.

- Model Driven Engineering
- definition : all the process of creating softwares with a model driven approach.
- examples : it includes some metamodel based analysis, how to manage teams with MDA,
which steps are required to create a real model based software factory, ...

- Model Driven Architecture
- definition : the technical choice of tool and metamodel for all the creation of a new software
- examples : transformation models engines, separation and links between PIM/CIM/and others

- Model Driven Software Development (also call MDD : Model Driven Development)
- definition : metamodel based tools and process for development step
- examples : source code generation (like Acceleo), PSM model based editor

- Domain Specific Modeling (and DSL : Domain Specific Language)
- definition : metamodel based modelers to design specific and semantical models
- examples : GMF based modelers, Workflow modelers, Wysiwig model based modelers

- Architecture Driven Modernization
- definition : modernize existing software with a metamodel approach
- examples : reverse engineering systems, recasting engine (like Agility)

Of course, let's do a metamodel of theses model driven definitions :
