## Description of `xl.meta`

`xl.meta` is a new self describing backend format used by MinIO to support AWS S3 compatible versioning.
This file is the source of truth for each `version` at rest. `xl.meta` is a msgpack file serialized from a

            doColumn("createdTime");
        }

        public void columnDepth() {
            doColumn("depth");
        }

        public void columnDescription() {
            doColumn("description");
        }

        public void columnExcludedDocPaths() {
            doColumn("excludedDocPaths");
        }

        public void columnExcludedPaths() {
            doColumn("excludedPaths");

And it will probably vary a lot from one app to the next.

It could be just one or two lines of code, like:

```Python
callback_url = "https://example.com/api/v1/invoices/events/"
httpx.post(callback_url, json={"description": "Invoice paid", "paid": True})
```

### 서브모듈을 타입으로 사용

그리고 어트리뷰트의 타입으로 사용할 수 있습니다:

{* ../../docs_src/body_nested_models/tutorial004.py hl[20] *}

이는 **FastAPI**가 다음과 유사한 본문을 기대한다는 것을 의미합니다:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

E provavelmente variará muito de um aplicativo para o outro.

Poderia ser apenas uma ou duas linhas de código, como:

```Python
callback_url = "https://example.com/api/v1/invoices/events/"
httpx.post(callback_url, json={"description": "Invoice paid", "paid": True})
```

  build_failed = 'build_failed'
  passed = 'passed'

Vous pouvez ajouter un `title` :

{* ../../docs_src/query_params_str_validations/tutorial007.py hl[10] *}

Et une `description` :

{* ../../docs_src/query_params_str_validations/tutorial008.py hl[13] *}

## Alias de paramètres

Imaginez que vous vouliez que votre paramètre se nomme `item-query`.
