## Abstract
|
|
|
|
This NIP enables a way for users to share live statuses such as what music they are listening to, as well as what they are currently doing: work, play, out of office, etc.
|
|
|
|
## Live Statuses
|
|
|
|
A special event with `kind:30315` "User Status" is defined as an *optionally expiring* _parameterized replaceable event_, where the `d` tag represents the status type:
|
|
|
|
For example:
|
|
|
|
```js
|
|
{
|
|
"kind": 30315,
|
|
"content": "Sign up for nostrasia!",
|
|
"tags": [
|
|
["d", "general"],
|
|
["r", "https://nostr.world"]
|
|
],
|
|
}
|
|
|
|
{
|
|
"kind": 30315,
|
|
"content": "Intergalatic - Beastie Boys",
|
|
"tags": [
|
|
["d", "music"],
|
|
["r", "spotify:search:Intergalatic%20-%20Beastie%20Boys"],
|
|
["expiration", "1692845589"]
|
|
],
|
|
}
|
|
```
|
|
|
|
Two common status types are defined: `general` and `music`. `general` represent general statuses: "Working", "Hiking", etc.
|
|
|
|
`music` status events are for live streaming what you are currently listening to. The expiry of the `music` status should be when the track will stop playing.
|
|
|
|
Any other status types can be used but they are not defined by this NIP.
|
|
|
|
The status MAY include an `r`, `p`, `e` or `a` tag linking to a URL, profile, note, or parameterized replaceable event.
|
|
|
|
# Client behavior
|
|
|
|
Clients MAY display this next to the username on posts or profiles to provide live user status information.
|
|
|
|
# Use Cases
|
|
|
|
* Calendar nostr apps that update your general status when you're in a meeting
|
|
* Nostr Nests that update your general status with a link to the nest when you join
|
|
* Nostr music streaming services that update your music status when you're listening
|
|
* Podcasting apps that update your music status when you're listening to a podcast, with a link for others to listen as well
|
|
* Clients can use the system media player to update playing music status
|
|
|
|
The `content` MAY be an emoji, or [NIP-30](30.md) custom emoji. If the `content` is an empty string then the client should clear the status.
