Custom Metadata Management

Users can set or change metadata freely according to the purpose of its use for the container or for the objects used in the object storage service.

Use an HTTP header in the custom metadata settings.

Setting/Changing Metadata

Name and set the metadata for the container or objects you want to use. To change metadata that has already been set, specify an existing metadata name to overwrite it.

Setting the metadata for the container

Use the format below to set the metadata.
```
X-Container-Meta-{Metadata Name}: {Metadata Value}
```
Setting the metadata for the objects

Use the format below to set the metadata.
```
X-Object-Meta-{Metadata Name}: {Metadata Value}
```
Note: Object metadata is set anew and the existing metadata is discarded. To keep the existing metadata, the user needs to set it again.

Deleting Metadata

Delete existing metadata. To delete the metadata, enter an empty character string for the existing metadata or use the format below.

Deleting the metadata of the container
```
X-Remove-Container-Meta-{Metadata Name}: {Metadata Value}
```
Tip: When you use the "X-Remove-" format, the specified metadata value is ignored.
