# Server Metadata
|
|
|
|
Contains metadata about a Versia instance, such as capabilities and endpoints. {{ className: 'lead' }}
|
|
|
|
<Note>
|
|
This entity is only used as part of [Server Discovery](/federation/discovery#server-discovery), and not as part of federation.
|
|
</Note>
|
|
|
|
## The `null` Author
|
|
|
|
On all entities that have an `author` field, the `author` can be `null` to represent the instance itself as the author (like ActivityPub's Server Actors). In this case, the instance's public key should be used to verify the entity.
