## What is Metadata?

Metadata is a data storage capability provided by repositories. Currently, it supports storing metadata for Tags and Commits, representing annotations for Tags or Commits.

## Storage Format

Stored in `key: value` format.

Taking Tag v1.0.0's metadata as an example, its metadata supports storage in `key: value` format, as shown below:

```yaml
key1: value1
key2: value2
# ...
```

## How to View Metadata?

Page navigation path:

* Tag metadata: Repository > Tag or Release list > Tag or Release details > Metadata (not shown if no metadata exists)
* Commit metadata: Repository > Commit list > Commit details > Metadata

Currently, the web interface only supports viewing metadata, not adding, modifying, or deleting.

## How to Operate on Metadata?

You can add, delete, and query metadata through plugins in Cloud Native Build pipelines.
