# FieldStructure

Specifies how to send subfield and field attribute data to Vertica.

You can choose one of the following options:

Option | Description
--- | ---
`Flattened` | The information is flattened.
`Nested` | Attributes and subfields are not flattened, instead they are represented as nested JSON objects. Use this mode to preserve the original structure of your documents. Documents can have multiple fields with the same name. Sending information in nested mode means that it is possible to see which field a sub-field or attribute was attached to.

The following is an example of flattened metadata, from an Image Server analysis task. The line `page.persontask.person.facelocation.angle` contains three sub-field values:

    "page.persontask" : "",
    "page.persontask.person" : "",
    "page.persontask.person.facelocation" : "",
    "page.persontask.person.facelocation.angle" : "11.9356031, -11.784749, -12.7712431",
    ...

The following is the same data represented by nested JSON objects:

    {
       "page":
       {
          "persontask":
          [
             {
             "person":
                {
                "facelocation" :
                   {
                   "angle": 11.9356031
                   ...
                   }
                }
             }
             {
             "person":
                {
                "facelocation":
                   {
                   "angle": -11.784749
                   ...
                   }
                }
             }
          ...
