## Documentation Tags - OpenAPI

To add tags to your *path operations*, and group them in the docs UI, read the docs for [Tutorial - Path Operation Configurations - Tags](../tutorial/path-operation-configuration.md#tags){.internal-link target=_blank}.

## Overview

   * {@code factory}, and the multimap contents are all serializable.
   *
   * <p>The multimap is not threadsafe when any concurrent operations update the multimap, even if
   * {@code map} and the instances generated by {@code factory} are. Concurrent read operations will
   * work correctly. To allow concurrent update operations, wrap the multimap with a call to {@link
   * #synchronizedMultimap}.

# Corpo - Campos

Da mesma forma que você pode declarar validações adicionais e metadados nos parâmetros de *funções de operações de rota* com `Query`, `Path` e `Body`, você pode declarar validações e metadados dentro de modelos do Pydantic usando `Field` do Pydantic.

## Importe `Field`

Primeiro, você tem que importá-lo:

```Python hl_lines="4"
{!../../docs_src/body_fields/tutorial001.py!}
```

/// warning | "Aviso"

But here's the key point.

The security and dependency injection stuff is written once.

And you can make it as complex as you want. And still, have it written only once, in a single place. With all the flexibility.

But you can have thousands of endpoints (*path operations*) using the same security system.

Você também pode adicionar metadados adicionais para as diferentes tags usadas para agrupar suas operações de rota com o parâmetro `openapi_tags`.

Ele recebe uma lista contendo um dicionário para cada tag.

Cada dicionário pode conter:

* `name` (**obrigatório**): uma `str` com o mesmo nome da tag que você usa no parâmetro `tags` nas suas *operações de rota* e `APIRouter`s.
