# Share Extension
The Share Extension lets users share notes they like with others. This is the same as Twitter's "retweet" and Mastodon's "boost". {{ className: 'lead' }}
## Behaviour
When a user shares a note, the note's original author **must** receive the entity alongside the user's followers. In clients, `Shares` should be rendered in a way that makes it clear that the shared note was originally authored by someone else than the user who shared it.
`Shares` can be undone ("unboosting") with a [Delete](/entities/delete) entity.
## Entity Definition
<Row>
<Col>
<Properties name="Share">
<Property name="type" type="string" required={true}>
Must be `pub.versia:share/Share`.
</Property>
<Property name="author" type="URI" required={true} typeLink="/types#uri">
Creator of the Share.
</Property>
<Property name="shared" type="URI" required={true} typeLink="/types#uri">
URI of the note being shared. Must link to a [Note](/entities/note).
</Property>
</Properties>
</Col>
<Col sticky>
```jsonc {{ 'title': 'Example Share' }}
{
"id": "3e7e4750-afd4-4d99-a256-02f0710a0520",
"type": "pub.versia:share/Share",
"created_at": "2021-01-01T00:00:00.000Z",
"author": "https://example.com/users/6e0204a2-746c-4972-8602-c4f37fc63bbe",
"uri": "https://example.com/shares/3e7e4750-afd4-4d99-a256-02f0710a0520",
"shared": "https://otherexample.org/notes/fmKZ763jzIU8"
}
```
</Col>
</Row>
## Note Collections
The Share extension adds the following collections to the [Note](/entities/note) entity:
- `shares`: A [URI Collection](/structures/collection#uri-collection) of all the shares of the note.
```jsonc
{
"type": "Note",
...
"collections": {
...
"pub.versia:share/Shares": "https://example.com/notes/fmKZ763jzIU8/shares"
}
}
```
## Interaction Types
<Note>
This section only applies to implementors of the [Interaction Controls Extension](/extensions/interaction-controls).
</Note>
This extension registers the following interaction types:
- `pub.versia:share#Share`, for sharing a Note.
