[news.eclipse.technology.jwt] Re: Building JWT workflows between plug-in

[Mickael Istria <mickael.istria@xxxxxxxxxxx>]

Hello ali, hello Florian,

Probably you should take a look at the Modeling Workflow Engine 
http://wiki.eclipse.org/Modeling_Workflow_Engine_(MWE) .
This project could be an interesting, light and Eclipse-friendly 
workflow engine for your use-case. However, I am not aware of the 
current status of this project, and JWT is does not yet allow you to 
produce flows in the MWE metamodel (should come one day...).

Hope that helps

Regards,
Mickael
