# Versia Links
Versia Links are a way to reference entities in the Versia Protocol, in a way that can be handled by browsers and applications. They function the same way as `mailto:` links, but for Versia entities.
## Syntax
<Row>
<Col>
<Properties name="Versia Link">
<Property name="scheme" type="string" required={true}>
Must be `web+versia://` so that browsers and applications can recognize it.
An IANA registration for the `versia://` scheme will be requested in the future.
</Property>
<Property name="action" type="string" required={true}>
Action to take on the entity. Can have multiple slashes as a way to segment the action.
Links that reference instance-specific content (like Entities) **must** reference a Instance.
Possible actions:
- `users/:instance/:id`: Open a user profile.
- `notes/:instance/:id`: Open a note.
- `groups/:instance/:id`: Open a group.
- `reply/:instance/:id`: Open the composer to reply to a note.
- `quote/:instance/:id`: Open the composer to quote a note.
- `share/:instance/:id`: Share a note.
- `compose/:text`: Compose a new note. Text passed at the end will be added in the note compose field. Used for "Share with Versia" buttons on websites.
</Property>
<Property name="instance" type="Domain" typeLink="/api/basics#domain" required={false}>
Instance hosting the referenced content.
</Property>

## Handling
Versia clients **should** register themselves as handlers for the `web+versia://` scheme in the user's operating system. When a Versia Link is clicked, the client should open the entity in the client's interface.
The default web client ("frontend") on a Versia instance **should** also display Versia links for logged-out users on:
- Profiles
- Notes
- Groups
This **could** be used for easier following of users from remote instances.
Clients **should** ask users to confirm any action that is not a simple view action, such as replying to a note or sharing a note.
