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

### Crear metadata para etiquetas

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.py hl[3:16,18] *}

     * `url` (**erforderlich**): ein `str` mit der URL für die externe Dokumentation.

### Metadaten für Tags erstellen

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

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

{* ../../docs_src/metadata/tutorial004.py hl[3:16,18] *}

  PATH_SEPARATOR("path.separator"),

  /** Line separator ("\n" on UNIX). */
  LINE_SEPARATOR("line.separator"),

  /** User's account name. */
  USER_NAME("user.name"),

  /** User's home directory. */
  USER_HOME("user.home"),

  /** User's current working directory. */
  USER_DIR("user.dir");

  private final String key;

  StandardSystemProperty(String key) {
    this.key = key;
  }
