## Déclarer des métadonnées

Vous pouvez déclarer les mêmes paramètres que pour `Query`.

Par exemple, pour déclarer une valeur de métadonnée `title` pour le paramètre de chemin `item_id`, vous pouvez écrire :

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[10] *}

/// note

	// the last result index sent to client
	lastSentResultIndex int64

	// Number of total items healed against item type
	healedItemsMap map[madmin.HealItemType]int64

	// Number of total items where healing failed against item type
	healFailedItemsMap map[madmin.HealItemType]int64
