Custom Metadata in Tarantool

It is often necessary to assign additional metadata to the objects extracted from images uploaded to the record index and now stored in the feature vector database.

In this section:

Customize Meta Fields of Face Objects 

To assign custom meta fields to the face objects, do the following:

Prepare the list of custom meta fields to assign.
Open the /opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.py configuration file.
```
sudo vi /opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.py
```

In the FFSECURITY section, uncomment the CUSTOM_FIELDS -> face_object section and modify the exemplary content, considering the following:

field_name: field’s name;
type: data type;
default: field’s default value. If a default value exceeds ‘1e14 – 1’, use a string data type to specify it, for example, "123123.." instead of 123123...

FFSECURITY = {

...

    # -- Custom model fields --
    ...
    # Edit CUSTOM_FIELDS -> `face_object` section to customize face object fields.
    ...
    # 'CUSTOM_FIELDS': {
          ...
          'face_object': {
              'items': [
                  {
                      "field_name": "tag_name_1",
                      "type": "string",
                      "default": "change_me"
                  },
                  {
                      "field_name": "tag_name_2",
                      "type": "uint",
                      "default": 123
                  },
                  {
                      "field_name": "tag_name_3",
                      "type": "bool",
                      "default": True
                  },
              ]
          }
      },
}

Add the new meta fields to the feature vector database structure.
Restart the findface-multi-findface-multi-legacy-1 container.
```
sudo docker container restart findface-multi-findface-multi-legacy-1
```
You can work with the new meta fields through HTTP API using the objects/faces/ methods.

Customize Meta Fields of Body and Vehicle Objects 

Assigning custom meta fields to the body and vehicle objects are similar to the faces. The only difference is that you will need to manually create the CUSTOM_FIELDS -> body_object and CUSTOM_FIELDS -> car_object sections. It is a good idea to duplicate the CUSTOM_FIELDS -> face_object section and use it as a starting point for further modifications.

FFSECURITY = {

...

    # -- Custom model fields --
    ...
    # Edit CUSTOM_FIELDS -> `face_object` section to customize face object fields.
    ...
    # 'CUSTOM_FIELDS': {
          ...
          'body_object': {
              'items': [
                  {
                      "field_name": "tag_name_1",
                      "type": "string",
                      "default": "change_me"
                  },
                  {
                      "field_name": "tag_name_2",
                      "type": "uint",
                      "default": 123
                  },
                  {
                      "field_name": "tag_name_3",
                      "type": "bool",
                      "default": True
                  },
              ]
          }
          'car_object': {
              'items': [
                  {
                      "field_name": "tag_name_1",
                      "type": "string",
                      "default": "change_me"
                  },
                  {
                      "field_name": "tag_name_2",
                      "type": "uint",
                      "default": 123
                  },
                  {
                      "field_name": "tag_name_3",
                      "type": "bool",
                      "default": True
                  },
              ]
          }
      },
}

Similarly, you can work with the new meta fields using the objects/bodies/ and objects/cars/ methods of HTTP API.
