[Fiware-tech-help] Regarding CEP input event json format

[Tali Yatzkar-Haham]

Dear Ahmed,

The CEP supports getting input events from Orion CB (using Orion XML 
output format). In your CEP consumer definition you need to specify that 
the contentType is: application/xml and the formatter is xml. 

You can see example for such consumer definition in the FIWARE livedemo 
CEP application (attached. you can import it to your CEP web UI), and 
explanations in the CEP user guide (appendix A)



Best regards,
Tali

Subject:        Regarding CEP input event json format



Dear Tali,

A quick question regarding posting events to CEP, I know that the format 
for input events is :

{"Name":"TrafficReport", "volume":"1000"}

But, the Orion context broker do generate JSON objects in this format:

{
  "subscriptionId" : "51c04a21d714fb3b37d7d5a7",
  "originator" : "localhost",
  "contextResponses" : [
    {
      "contextElement" : {
        "attributes" : [
          {
            "name" : "temperature",
            "type" : "float",
            "value" : "26.5"
          }
        ],
        "type" : "Room",
        "isPattern" : "false",
        "id" : "Room1"
      },
      "statusCode" : {
        "code" : "200",
        "reasonPhrase" : "OK"
      }
    }
  ]
}

So is there a way to make CEP accept this input event and check that the 
temperature value is between certain threshold this condition:
TR1.value>0 AND TR1.value<30

Currently, I am getting this error :

Could not parse json event org.apache.wink.json4j.JSONException: The key 
[Name] was not in the map, reason: The key [Name] was not in the map

Since there is no Name of course. 

Please let me know if you have a solution or suggestions.

Best,
Ahmed Sadek
