Each Labeling result is the combination of Annotation and Attribute Result.Attribute Result is the question & answer regarding the annotation or the task. There are 2 type of Attribute Result.

Base structure of AttributeResult is

{
  "attribute_key" : "What is in the image",
  "attribute_value_list" : {
    "value" : [ "car" ]
  }
}

¶ 1. Task Attribute Result

This attribute Result key depends on the worktype for example for Image Labeling key will be image_attribute_results and for image segmentation key will be image_semantic_segmentation_attribute_results

"image_attribute_results" : [ {
  "attribute_key" : "What is in the image",
  "attribute_value_list" : {
    "value" : [ "Bus" ]
  }
} ]

¶ 2. Annotation Level Attribute Result

For annotation level attribute result it will come in the annotation itself Below is the Example of ANNOTATION_TYPE_SEGMENTATION with annotation level attribute result

{
  "annotation_label" : {
    "title" : "Car"
  },
  "annotation_type" : "ANNOTATION_TYPE_SEGMENTATION",
  "annotation_data" : {
    "attribute_results" : [ {
      "attribute_key" : "Is this car a sedan",
      "attribute_value_list" : {
        "value" : [ "Yes" ]
      }
    } , {
      "attribute_key" : "What is the color of the car",
      "attribute_value_list" : {
        "value" : [ "blue" ]
      }
    }]
  }
    //the segmentation data would also be there
}
