더 오래된 버전이 있다면 `Annotated`를 사용하려고 할 때 오류가 발생합니다.

`Annotated`를 사용하기 전에 최소 0.95.1까지 [FastAPI 버전 업그레이드](../deployment/versions.md#upgrading-the-fastapi-versions)를 꼭 하세요.

///

## 메타데이터 선언 { #declare-metadata }

`Query`에 동일한 매개변수를 선언할 수 있습니다.

예를 들어, 경로 매개변수 `item_id`에 `title` 메타데이터 값을 선언하려면 다음과 같이 입력할 수 있습니다:

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[10] *}

/// note | 참고

如果你使用的是更旧的版本，尝试使用 `Annotated` 会报错。

请确保在使用 `Annotated` 之前，将 FastAPI 版本[升级](../deployment/versions.md#upgrading-the-fastapi-versions)到至少 0.95.1。

///

## 声明元数据 { #declare-metadata }

你可以声明与 `Query` 相同的所有参数。

例如，要为路径参数 `item_id` 声明 `title` 元数据值，你可以这样写：

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[10] *}

Aynı tekniği JSON Schema’yı genişletmek ve kendi özel ek bilgilerinizi eklemek için de kullanabilirsiniz.

Örneğin, bir frontend kullanıcı arayüzü için metadata eklemek vb. amaçlarla kullanılabilir.

OpenAPI 3.1.0 (FastAPI 0.99.0’dan beri kullanılıyor), **JSON Schema** standardının bir parçası olan `examples` için destek ekledi.

- The rules for incrementing `metadata.generation` of custom resources changed: ([#69059](https://github.com/kubernetes/kubernetes/pull/69059), [@caesarxuchao](https://github.com/caesarxuchao))
  - If the custom resource participates the spec/status convention, the metadata.generation of the CR increments when there is any change, except for the changes to the metadata or the changes to the status.
