型宣言の標準的なPythonの構文はこれだけです。

内部の型を持つモデルの属性にも同じ標準の構文を使用してください。

そのため、以下の例では`tags`を具体的な「文字列のリスト」にすることができます:

{* ../../docs_src/body_nested_models/tutorial002.py hl[14] *}

## セット型

しかし、よく考えてみると、タグは繰り返すべきではなく、おそらくユニークな文字列になるのではないかと気付いたとします。

そして、Pythonにはユニークな項目のセットのための特別なデータ型`set`があります。

そのため、以下のように、`Set`をインポートして`str`の`set`として`tags`を宣言することができます:

{* ../../docs_src/body_nested_models/tutorial003.py hl[1,14] *}

/// tip

사용 중인 모든 태그에 메타데이터를 추가할 필요는 없습니다.

///

### 태그 사용

`tags` 매개변수를 *경로 작동* 및 `APIRouter`와 함께 사용하여 태그에 할당할 수 있습니다:

{* ../../docs_src/metadata/tutorial004.py hl[21,26] *}

/// info

태그에 대한 자세한 내용은 [경로 작동 구성](path-operation-configuration.md#tags){.internal-link target=_blank}에서 읽어보세요.

### 문서 확인

이제 문서를 확인하면 모든 추가 메타데이터가 표시됩니다:

			objInfo.Expires = t.UTC()
		}
	}

	// Extract etag from metadata.
	objInfo.ETag = extractETag(fi.Metadata)

	// Add user tags to the object info
	tags := fi.Metadata[xhttp.AmzObjectTagging]
	if len(tags) != 0 {
		objInfo.UserTags = tags
	}

	// Add replication status to the object info
	objInfo.ReplicationStatusInternal = fi.ReplicationState.ReplicationStatusInternal
