用raphael画一个流程图，将流程图的数据变成有层级的json类型，传给Conductor

Question

我现在需要做一个编排器，前端的页面是自定义的，可以拖动服务和逻辑判断；
当前用raphael自定义出来一个流程图，可是raphael的数据结构是这样的：

{
                        "nodes":[
                            {
                                "nodecode":"DEV001",
                                "nodetype":"first",
                                "nodestat":{
                                    "main":0
                                },
                                "nodedesc":"",
                                "nodename":"开始",
                                "posx":478,
                                "posy":160
                            },
                            {
                                "nodecode":"DEV002",

                    }

但是conductor接收的json数据类型是下面这种格式的 是有层级关系的
