There are several bpmn online javasctipt editors. One of the simpliest is: http://www.gojs.net/latest/extensions/BPMN.html But it seems each online editor uses its own json format to represent the same bpmn models.
Is there any online editor that use the same json format as activity convertor does? I want to edit process, send json file to server, save it, process by activity and probably send it back.
How can I reuse or implement it in the simplest way?
