Proxy Tags
|
|
----------
|
|

`draft` `optional` `author:alexgleason`
|
|
|
|
Nostr events bridged from other protocols such as ActivityPub can link back to the source object by including a `"proxy"` tag, in the form:
|
|
|
|
```
|
|
["proxy", <id>, <protocol>]
|
|
```
|
|
|
|
Where:
|
|
|
|
- `<id>` is the ID of the source object. The ID format varies depending on the protocol. The ID must be universally unique, regardless of the protocol.
|
|
- `<protocol>` is the name of the protocol, e.g. `"activitypub"`.
|
|
|
|
Clients may use this information to reconcile duplicated content bridged from other protocols, or to display a link to the source object.
|
|
|
|
Proxy tags may be added to any event kind, and doing so indicates that the event did not originate on the Nostr protocol, and instead originated elsewhere on the web.
|
|
|
|
