## Tag'ler için Metadata { #metadata-for-tags }

`openapi_tags` parametresiyle, path operation'larınızı gruplamak için kullandığınız farklı tag'ler adına ek metadata da ekleyebilirsiniz.

Bu parametre, her tag için bir sözlük (dictionary) içeren bir liste alır.

Her sözlük şunları içerebilir:

* `name` (**zorunlu**): *path operation*'larda ve `APIRouter`'larda `tags` parametresinde kullandığınız tag adıyla aynı olan bir `str`.

## Metadata for tags { #metadata-for-tags }

You can also add additional metadata for the different tags used to group your path operations with the parameter `openapi_tags`.

It takes a list containing one dictionary for each tag.

Each dictionary can contain:

* `name` (**required**): a `str` with the same tag name you use in the `tags` parameter in your *path operations* and `APIRouter`s.
