(OP for the [Flowable Modeler vs Activiti Modeling App](https://forum.flowable.org/t/flowable-modeler-vs-activiti-modeling-app/5680) post that kicked this off)

Having scoured the interwebs and found nothing better, we’re considering either sticking with KIS BPM (Yuck!) or the same approach as @donkon : extending and using bpmn-js. The main part missing from the bpmn-js modeler is property support for activiti: prefixed properties. There’s a camunda extension in github but no activiti equivalent.  
☹  
@donkon - would you consider opensourcing yours?

On the license issue raised by @PHH : Makes sense, but is a damn shame, since bpmn-js extensions would be such a simple approach. It might be worth trying to a) negotiate those license terms with Camunda (since it is mostly MIT except for the logo) or starting with diagram-js which is MIT. (search for license questions on the bmpn io forum)

cheers
