# Label verification and adjustment data in the output manifest
<a name="sms-data-verify-manifest"></a>

Amazon SageMaker Ground Truth writes label verification data to the output manifest within the metadata for the label. It adds two properties to the metadata:
+ A `type` property, with a value of "`groundtruth/label-verification`.
+ A `worker-feedback` property, with an array of `comment` values. This property is added when the worker enters comments. If there are no comments, the field doesn't appear.

The following example output manifest shows how label verification data appears:

```
{
  "source-ref":"S3 bucket location", 
  "verify-bounding-box":"1",    
  "verify-bounding-box-metadata":  
  {
    "class-name": "bad", 
    "confidence": 0.93, 
    "type": "groundtruth/label-verification", 
    "job-name": "verify-bounding-boxes",
    "human-annotated": "yes",
    "creation-date": "2018-10-18T22:18:13.527256",
    "worker-feedback": [
      {"comment": "The bounding box on the bird is too wide on the right side."},
      {"comment": "The bird on the upper right is not labeled."}
    ]
  }
}
```

The worker output of adjustment tasks resembles the worker output of the original task, except that it contains the adjusted values and an `adjustment-status` property with the value of `adjusted` or `unadjusted` to indicate whether an adjustment was made.
