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

**Note**  
After careful consideration, we have made the decision to close new customer access to AWS Ground Truth, effective 7/30/26. Existing customers can continue to use the service as normal. AWS continues to invest in security and availability improvements for Ground Truth, but we do not plan to introduce new features.

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.

For more examples of the output of different tasks, see [Labeling job output data](sms-data-output.md).
