Are you aware of any free/open-source/licensed online(browser-based) UML/BPM application that can help users chalk out their business processes using BPM notations. UML notations might also do since we want to use simple diagram editor. I came across Gliffy and a few others but the issue there is that they offer this as a hosted service. I am looking for an application that I can deploy on my server and users can then design their business processes by accessing that application on a browser. I am not looking for automatic source-code generation.
Your help appreciated. Feel free to ask me any questions regarding this requirement.
