Zigbee device -> application, manufacturer, model

Hi,
Im currently developing a Zigbee Device with Simplicity Studio.

I defined in my device:

  "endpointTypes": [
    {
      "name": "AeotecPowerPlug",
      "deviceTypeName": "HA-mpo",
      "deviceTypeCode": 9,
      "deviceTypeProfileId": 260,

but in the Gateway I only get:

"zbjoin":{
   "dni":"6C83",
   "d":"3425B4FFFEA0B42A",
   "capabilities":"8C",
   "endpoints":[
      {
         "simple":"01 0104 0009 01 06 0000 0003 0004 0005 0006 0B04 01 0003",
         "application":null,
         "manufacturer":null,
         "model":null
      }
   ],
   "parent":0,
   "joinType":1,
   "joinDurationMs":2569,
   "joinAttempts":1
}

So what is meant by application, manufacturer and model from a Zigbee perspective?
