### Metadaten für Tags erstellen { #create-metadata-for-tags }

Versuchen wir es mit einem Beispiel mit Tags für `users` und `items`.

Erstellen Sie Metadaten für Ihre Tags und übergeben Sie diese an den Parameter `openapi_tags`:

{* ../../docs_src/metadata/tutorial004_py39.py hl[3:16,18] *}

    * `url` (**requerido**): un `str` con la URL para la documentación externa.

### Crear metadata para etiquetas { #create-metadata-for-tags }

Probemos eso en un ejemplo con etiquetas para `users` y `items`.

Crea metadata para tus etiquetas y pásala al parámetro `openapi_tags`:

{* ../../docs_src/metadata/tutorial004_py39.py hl[3:16,18] *}

   * explained in the {@link Comparator} documentation.
