======
User Statuses
--------------

`draft` `optional`
## 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.
The `content` MAY include emoji(s), or [NIP-30](30.md) custom emoji(s). If the `content` is an empty string then the client should clear the status.
# 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
