## Decoding Metadata

Metadata is stored in `xl.meta` files for erasure coded objects. Each disk in the set containing the object has this file. The file format is a binary format and therefore requires tools to view values.

### Installing xl-meta

To install, [Go](https://golang.org/dl/) must be installed. Once installed, execute this to install the binary:

```bash
go install github.com/minio/minio/docs/debugging/xl-meta@latest

#### About `**user_dict` { #about-user-dict }

`UserInDB(**user_dict)` means:

*Pass the keys and values of the `user_dict` directly as key-value arguments, equivalent to:*

```Python
UserInDB(
    username = user_dict["username"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],

	h.Modified = t
	h.ModifiedDate, h.ModifiedTime = timeToMsDosTime(t)
}

const (
	// Unix constants. The specification doesn't mention them,
	// but these seem to be the values agreed on by tools.
	s_IFMT   = 0xf000
	s_IFSOCK = 0xc000
	s_IFLNK  = 0xa000
	s_IFREG  = 0x8000
	s_IFBLK  = 0x6000
	s_IFDIR  = 0x4000
	s_IFCHR  = 0x2000
	s_IFIFO  = 0x1000
	s_ISUID  = 0x800

            realm.setParentRealm(parentRealm);
        } else {
            throw new IllegalArgumentException("Unsupported class-loading strategy '"
                    + classLoadingStrategy + "'. Supported values are: " + STRATEGY_PARENT_FIRST
                    + ", " + STRATEGY_PLUGIN + " and " + STRATEGY_SELF_FIRST);
        }
        log.debug("Populating class realm {}", realm.getId());

Pydantic { #without-pydantic }

Wenn Sie keine Pydantic-Modelle verwenden möchten, können Sie auch **Body**-Parameter verwenden. Siehe die Dokumentation unter [Body – Mehrere Parameter: Einfache Werte im Body](body-multiple-params.md#singular-values-in-body){.internal-link target=_blank}....

### Step 5: return the content { #step-5-return-the-content }

{* ../../docs_src/first_steps/tutorial001_py39.py hl[8] *}

You can return a `dict`, `list`, singular values as `str`, `int`, etc.

You can also return Pydantic models (you'll see more about that later).

#### Obtenha o valor da enumeração { #get-the-enumeration-value }

Você pode obter o valor real (um `str` neste caso) usando `model_name.value`, ou, em geral, `your_enum_member.value`:

{* ../../docs_src/path_params/tutorial005_py39.py hl[20] *}

/// tip | Dica
Você também pode acessar o valor `"lenet"` com `ModelName.lenet.value`.
