## 標籤的中繼資料 { #metadata-for-tags }

你也可以透過 `openapi_tags` 參數，為用來分組你的路徑操作（path operation）的各個標籤加入額外中繼資料。

它接收一個 list，其中每個標籤對應一個 dictionary。

每個 dictionary 可包含：

* `name`（**必填**）：一個 `str`，其值需與你在路徑操作與 `APIRouter`s 的 `tags` 參數中使用的標籤名稱相同。
* `description`：一個 `str`，為該標籤的簡短描述。可使用 Markdown，並會顯示在文件介面中。
* `externalDocs`：一個 `dict`，描述外部文件，包含：
