Subject [SCXML] Re: SCXML project
Date Sat, 23 Jan 2016 00:33:29 GMT
Hi Guilherme,

I have used SCXML for use cases outside of telecom, including to control hardware in industrial
systems. Semantically, SCXML has most of the features of Statecharts, the language upon which
Stateflow is based, and it works well for this use case.

Unlike Stateflow, SCXML does not have a dedicated graphical IDE. The development I have done
has primarily involved editing SCXML by hand, and applying automated visualization using D3.
I have heard of other SCXML developers doing the same. I believe MagicDraw <>
supports SCXML, but I have not tried it. 

There are also semantic difference between SCXML and Stateflow. For example, transition priority:
Stateflow uses a graphical syntax, based on a clockwise <>
ordering, while SCXML relies on document order of the transition nodes in the XML document.

It would be interesting to combine an SCXML engine with open source software for modeling
system dynamics, such as Modelica <>  Xcos <>,
or Minsky <>, to create an open stack of simulation

Please feel free to reach me with any questions. Thank you,

Jacob Beard
