This NIP defines lists of things that users can create. Lists can contain references to anything, and these references can be **public** or **private**. This NIP defines lists of things that users can create. Lists can contain references to anything, and these

Public items in a list are specified in the event `tags` array, while private items are specified in a JSON array that mimics the structure of the event `tags` array, but stringified and encrypted using the same scheme from [NIP-04](04.md) (the shared key is computed using the author's public and private key) and stored in the `.content`.

## Generic lists ## Types of lists
The kinds `30000` and `30001` have been reserved for generic lists. These must be accompanied by a `d` tag identifying the list, but these are generally client-specific, except in the standard cases specified below. ### Generic lists
### Standard lists The kind `30001` has been reserved for generic lists. These must be accompanied by a `d` tag identifying the
list, but these have no standard meaning and are generally client-specific (except in the standard cases
specified below).
These are some standards that emerged in the wild: ## Standard lists
Users are expected to have a single list of each of these types. They have special meaning and clients may
rely on them to augment the user profile or browsing experience.
For example, _mute lists_ can contain the public keys of spammers and bad actors users don't want to see in
their feeds or receive annoying notifications from.
| name | kind | "d" tag | description | expected tag items | | name | kind | "d" tag | description | expected tag items |
| --- | --- | --- | --- | --- | | --- | --- | --- | --- | --- |
| Mute list | 30000 | `"mute"` | things the user doesn't want to see in their feeds | `"p"` (pubkeys), `"t"` (hashtags) | | Mute list | 10000 | | things the user doesn't want to see in their feeds | `"p"` (pubkeys), `"t"` (hashtags) |

## Sets ## Sets
Sets are lists with well-defined meaning and purpose and user-assigned `d` tags meant to be displayed in the UI. For example, _relay sets_ can be displayed in a dropdown UI to give users the option to switch to which relays they will publish an event or from which relays they will read the replies to an event; or _curation sets_ can be used by apps to showcase curations made by others tagged to different topics. Sets are lists with well-defined meaning that can enhance the functionality and the UI of clients that rely
on them. Unlike standard lists, users are expected to have more than one set of each kind, therefore each of
them must be assigned a different `"d"` identifier.
Aside from their main identifier, the `"d"` tag, sets can optionally have a `"title"`, an `"image"` and a `"description"` tag that can be used to enhance their UI. For example, _relay sets_ can be displayed in a dropdown UI to give users the option to switch to which
relays they will publish an event or from which relays they will read the replies to an event; _curation sets_
can be used by apps to showcase curations made by others tagged to different topics.
Aside from their main identifier, the `"d"` tag, sets can optionally have a `"title"`, an `"image"` and a
`"description"` tag that can be used to enhance their UI.
| name | kind | description | expected tag items | | name | kind | description | expected tag items |
| --- | --- | --- | --- | | --- | --- | --- | --- |
| Relay sets | 30002 | user-defined relay groups the user can easily pick and choose from during variadic operations | `"relay"` (relay URLs) | | Relay sets | 30002 | user-defined relay groups the user can easily pick and choose from during variadic operations | `"relay"` (relay URLs) |
| Article Curation sets | 30003 | groups of articles picked by users as interesting and/or belonging to the same category | `"a"` (kind:30023 articles) | | Article Curation sets | 30004 | groups of articles picked by users as interesting and/or belonging to the same category | `"a"` (kind:30023 articles), `"e"` (kind:1 notes) |
## Deprecated standard lists
Some clients have used these lists in the past, but they should work on transitioning to the [standard formats](#standard-lists) above:
- kind:30000 and `d` "mute"
| kind | "d" tag | use instead |
| --- | --- | --- |
| 30000 | `"mute"` | kind 10000 _mute list_ |
