I wanted ask the community for some help for developing a plugin for papyrus for code generation based on StateMachines.
I want to create my own code generation algorithm and so I needed to access the UML meta model... how can I do this? what is the API to access this kind of information? where can I read about it? (does it existes?) is there any open source plugin (template)... I can study to understand how to create a simple plugin for Eclipse Papyrus extension?

I would be very grateful if you could help in some way,

Francisco Dias

First, we (Zeligsoft), in collaboration with the Papyrus team (and others) are developing a Papyrus-based open-source development environment for UML-RT which includes code generation for state machines. However we deal with UML-RT state machines which simplify full UML state machines. Support for full UML state machines is rather tricky, as you'll probably find out.

While the project is open source, it is still in very early stages, and even though the state machine code generator is almost finished, it's still a bit too early to release it, even in alpha. But we will surely announce it here when it's ready.

As for the UML API and meta-model, yes, there is a meta-model and an API. Your starting point should be the official OMG UML specification ( Papyrus follows it closely.

To get access to the UML meta-model, you should probably download the papyrus sources, and you'll find the relevant classes in package "org.eclipse.uml2.uml". Eclipse will give you access to all of the API.

However, I would strongly recommend using the Oomph installer ( to get an environment for Papyrus development. It will provide you with just the elements from Papyrus that you might need.

Please note that the UML2 metamodel and API is not a part of Papyrus; we depend on this project. You should have a look at the Eclipse/UML2 project for the Metamodel and API. Papyrus doesn't provide any specific code generation framework either. You should probably have a look at the Acceleo or Xtend projects (I know Acceleo has some examples of generating code from UML; not sure for Xtend since it is more a general purpose programming language rather than a code generation language)

Hi Ernesto,

this project sounds very interesting. I'm also involved in a project which develops code generation for embedded systems based on UML models. We also want to offer an integration to papyrus based IDEs.
Where can I get more information about your project?

Kind regards,
