Fiware 如何配置Cepheus CEP，使其将json而不是xml返回到orion？

最近我开始使用Cepheus CEP，但根据文档，我无法将其插入orion实体。查看acculator.py的错误，我发现cepheus cep向orion发送xml查询。xml在orion中不是被弃用了吗

cepheus cep中使用的配置：

{
  "host":"http://localhost:1028",
  "in":[
    {
      "id":"Room.*",
      "type":"Room",
      "isPattern":true,
      "providers":[
        "http://localhost:1027"
      ],
      "attributes":[
        { "name":"temperature", "type":"double" },
        { "name":"floor", "type":"string" }
      ]
    }
  ],
  "out":[
    {
      "id":"Floor1",
      "type":"Floor",
      "brokers":[
        {
          "url":"http://localhost:1029"
        }
      ],
      "attributes":[
        { "name":"temperature", "type":"double" }
      ]
    }
  ],
  "statements":[
    "INSERT INTO Floor SELECT floor as id, avg(temperature) as temperature FROM Room.win:time(10 min) GROUP BY floor OUTPUT LAST EVERY 10 sec"
  ]
}

我对acculator.py的反应是：

127.0.0.1 - - [13/May/2016 05:50:46] "POST /ngsi10/updateContext HTTP/1.1" 200 -

使用正确的代理配置，我会出现以下错误：

2016-05-13 06:07:08.504  WARN 12977 --- [nio-1027-exec-8] c.o.c.broker.controller.NgsiController   : UpdateContext failed for http://localhost:1026: org.springframework.web.client.HttpClientErrorException: 415 Unsupported Media Type

我认为产生此错误的原因还在于查询的xml格式。

Cepheus 0.1.16与0.28之后的Orion不兼容，因为xml支持已被删除。我向Cepheus添加了一个问题以跟踪此问题：

[更新]以JSON作为NGSI交换的默认格式发布。

谢谢。你知道发行日期吗？
