RGen is a framework supporting Model Driven Software Development (MDSD). This means that it helps you build Metamodels, instantiate Models, modify and transform Models and finally generate arbitrary textual content from it.
RGen features include:
-
Programmatic definition of Metamodels
-
ECore as Metametamodel with an ECore instance available for every Metamodel
-
Generator for programmatic Metamodel from ECore instance
-
Instantiation of Metamodels, i.e. creation of Models (e.g. from XML)
-
Model Transformations
-
Powerful template based generator language
-
A growing set of included Metamodels, Transformations, Generators:
-
UML 1.3 Metamodel
-
XMI 1.1 Instantiator
-
XMI 2.0 Instantiator, currently use to read ECore instances only
