including distributed moderation, collection management, license assignment, and content classification.
This NIP introduces two new tags:
- `L` denotes a label namespace
- `l` denotes a label
Label Namespace Tag
----
An `L` tag can be any string, but publishers SHOULD ensure they are unambiguous by using a well-defined namespace
(such as an ISO standard) or reverse domain name notation.
`L` tags are REQUIRED in order to support searching by namespace rather than by a specific tag. The special `ugc`
("user generated content") namespace MAY be used when the label content is provided by an end user.
`L` tags starting with `#` indicate that the label target should be associated with the label's value.
This is a way of attaching standard nostr tags to events, pubkeys, relays, urls, etc.

Label Tag
----
This NIP introduces a new tag `l` which denotes a label, and a new `L` tag which denotes a label namespace.
A label MUST include a mark matching an `L` tag. `L` tags refer to a tag type within nostr, or a nomenclature
external to nostr defined either formally or by convention. Any string can be a namespace, but publishers SHOULD
ensure they are unambiguous by using a well-defined namespace (such as an ISO standard) or reverse domain name notation.
Namespaces starting with `#` indicate that the label target should be associated with the label's value.
This is a way of attaching standard nostr tags to events, pubkeys, relays, urls, etc.
Some examples:
- `["l", "footstr", "#t"]` - the publisher thinks the given entity should have the `footstr` topic applied.
- `["l", "<pubkey>", "#p"]` - the publisher thinks the given entity is related to `<pubkey>`
- `["l", "IT-MI", "ISO-3166-2"]` - Milano, Italy using ISO 3166-2.
- `["l", "VI-hum", "com.example.ontology"]` - Violence toward a human being as defined by ontology.example.com.
`L` tags containing the label namespaces MUST be included in order to support searching by
namespace rather than by a specific tag. The special `ugc` ("user generated content") namespace
MAY be used when the label content is provided by an end user.
`l` and `L` tags MAY be added to other event kinds to support self-reporting. For events
with a kind other than 1985, labels refer to the event itself.
Label Annotations
-----
A label tag MAY include a 4th positional element detailing extra metadata about the label in question. This string
should be a json-encoded object. Any key MAY be used, but the following are recommended:
- `quality` may have a value of 0 to 1. This allows for an absolute, granular scale that can be represented in any way (5 stars, color scale, etc).
- `confidence` may have a value of 0 to 1. This indicates the certainty which the author has about their rating.
- `context` may be an array of urls (including NIP-21 urls) indicating other context that should be considered when interpreting labels.
Content Content
------- -------
Labels should be short, meaningful strings. Longer discussions, such as for a review, or an Labels should be short, meaningful strings. Longer discussions, such as for a review, or an

Lists Lists
----- -----
`draft` `optional` `author:fiatjaf` `author:arcbtc` `author:monlovesmango` `author:eskema` `author:gzuuus` `draft` `optional`
A "list" event is defined as having a list of public and/or private tags. Public tags will be listed in the event `tags`. Private tags will be encrypted in the event `content`. Encryption for private tags will use [NIP-04 - Encrypted Direct Message](04.md) encryption, using the list author's private and public key for the shared secret. A distinct event kind should be used for each list type created. This NIP defines lists of things that users can create. Lists can contain references to anything, and these references can be **public** or **private**.
If a list should only be defined once per user (like the "mute" list) the list is declared as a _replaceable event_. These lists may be referred to as "replaceable lists". Otherwise, the list is a _parameterized replaceable event_ and the list name will be used as the `d` tag. These lists may be referred to as "parameterized replaceable lists". 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`.
## Replaceable List Event Example ## Types of lists
Lets say a user wants to create a 'Mute' list and has keys: ## Standard lists
```
priv: fb505c65d4df950f5d28c9e4d285ee12ffaf315deef1fc24e3c7cd1e7e35f2b1
pub: b1a5c93edcc8d586566fde53a20bdb50049a97b15483cb763854e57016e0fa3d
```
The user wants to publicly include these users:
```json Standard lists use non-parameterized replaceable events, meaning users may only have a single list of each kind. They have special meaning and clients may rely on them to augment a user's profile or browsing experience.
["p", "3bf0c63fcb93463407af97a5e5ee64fa883d107ef9e558472c4eb9aaaefa459d"],
["p", "32e1827635450ebb3c5a7d12c1f8e7b2b514439ac10a67eef3d9fd9c5c68e245"]
```
and privately include these users (below is the JSON that would be encrypted and placed in the event content):
```json 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.
[
["p", "9ec7a778167afb1d30c4833de9322da0c08ba71a69e1911d5578d3144bb56437"],
["p", "8c0da4862130283ff9e67d889df264177a508974e2feb96de139804ea66d6168"]
]
```
Then the user would create a 'Mute' list event like below: | name | kind | description | expected tag items |
| --- | --- | --- | --- |
| Mute list | 10000 | things the user doesn't want to see in their feeds | `"p"` (pubkeys), `"t"` (hashtags), `"word"` (lowercase string), `"e"` (threads) |
| Pinned notes | 10001 | events the user intends to showcase in their profile page | `"e"` (kind:1 notes) |
| Bookmarks | 10003 | uncategorized, "global" list of things a user wants to save | `"e"` (kind:1 notes), `"a"` (kind:30023 articles), `"t"` (hashtags), `"r" (URLs)` |
| Communities | 10004 | [NIP-72](72.md) communities the user belongs to | `"a"` (kind:34550 community definitions) |
| Public chats | 10005 | [NIP-28](28.md) chat channels the user is in | `"e"` (kind:40 channel definitions) |
| Blocked relays | 10006 | relays clients should never connect to | `"relay"` (relay URLs) |
| Search relays | 10007 | relays clients should use when performing search queries | `"relay"` (relay URLs) |
| Interests | 10015 | topics a user may be interested in and pointers | `"t"` (hashtags) and `"a" (kind:30015 interest set)` |
| Emojis | 10030 | user preferred emojis and pointers to emoji sets | `"emoji"` (see [NIP-30](30.md)) and `"a"` (kind:30030 emoji set) |
## Sets
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.
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"` tags that can be used to enhance their UI.
| name | kind | description | expected tag items |
| --- | --- | --- | --- |
| Follow sets | 30000 | categorized groups of users a client may choose to check out in different circumstances | `"p"` (pubkeys) |
| Relay sets | 30002 | user-defined relay groups the user can easily pick and choose from during various operations | `"relay"` (relay URLs) |
| Bookmark sets | 30003 | user-defined bookmarks categories , for when bookmarks must be in labeled separate groups | `"e"` (kind:1 notes), `"a"` (kind:30023 articles), `"t"` (hashtags), `"r" (URLs)` |
| 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) |
| Interest sets | 30015 | interest topics represented by a bunch of "hashtags" | `"t"` (hashtags) |
| Emoji sets | 30030 | categorized emoji groups | `"emoji"` (see [NIP-30](30.md)) |
## 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 | "d" tag | use instead |
| --- | --- | --- |
| 30000 | `"mute"` | kind 10000 _mute list_ |
| 30001 | `"pin"` | kind 10001 _pin list_ |
| 30001 | `"bookmark"` | kind 10003 _bookmarks list_ |
| 30001 | `"communities"` | kind 10004 _communities list_ |

| ------ | ----------------------- |
| 10000 | Mute |
| 10001 | Pin |
| 30000 | Categorized People |
| 30001 | Categorized Bookmarks |
### Mute List
An event with kind `10000` is defined as a replaceable list event for listing content a user wants to mute. Any standardized tag can be included in a Mute List.
### Pin List
An event with kind `10001` is defined as a replaceable list event for listing content a user wants to pin. Any standardized tag can be included in a Pin List.
### Categorized People List
An event with kind `30000` is defined as a parameterized replaceable list event for categorizing people. The 'd' parameter for this event holds the category name of the list. The tags included in these lists MUST follow the format of kind 3 events as defined in [NIP-02 - Contact List and Petnames](02.md).
### Categorized Bookmarks List
An event of kind `30001` is defined as a parameterized replaceable list event for categorizing bookmarks. The 'd' parameter for this event holds the category name of the list. The bookmark lists may contain metadata tags such as 'title', 'image', 'summary' as defined in [NIP-23 - Long-form Content](23.md). Any standardized tag can be included in a Categorized Bookmark List.

## Abstract
Service providers want to offer live activities to the Nostr network in such a way that participants can easily logged and queried by clients. This NIP describes a general framework to advertise the involvement of pubkeys in such live activities.

# Live Event ## Concepts
### Live Event
A special event with `kind:30311` "Live Event" is defined as a _parameterized replaceable event_ of public `p` tags. Each `p` tag SHOULD have a **displayable** marker name for the current role (e.g. `Host`, `Speaker`, `Participant`) of the user in the event and the relay information MAY be empty. This event will be constantly updated as participants join and leave the activity. A special event with `kind:30311` "Live Event" is defined as a _parameterized replaceable event_ of public `p` tags.

## Proof of Agreement to Participate ### Proof of Agreement to Participate
Event owners can add proof as the 5th term in each `p` tag to clarify the participant's agreement in joining the event. The proof is a signed SHA256 of the complete `a` Tag of the event (`kind:pubkey:dTag`) by each `p`'s private key, encoded in hex.

Highlights
----------
`draft` `optional`
This NIP defines `kind:9802`, a "highlight" event, to signal content a user finds valuable.
## Format
The `.content` of these events is the highlighted portion of the text.
`.content` might be empty for highlights of non-text based media (e.g. NIP-94 audio/video).
### References
Events SHOULD tag the source of the highlight, whether nostr-native or not.
`a` or `e` tags should be used for nostr events and `r` tags for URLs.
When tagging a URL, clients generating these events SHOULD do a best effort of cleaning the URL from trackers
or obvious non-useful information from the query string.
### Attribution
Clients MAY include one or more `p` tags, tagging the original authors of the material being highlighted; this is particularly
useful when highlighting non-nostr content for which the client might be able to get a nostr pubkey somehow
(e.g. prompting the user or reading a `<meta name="nostr:nprofile1..." />` tag on the document). A role MAY be included as the
last value of the tag.
```json
{
"tags": [
["p", "<pubkey-hex>", "<relay-url>", "author"],
["p", "<pubkey-hex>", "<relay-url>", "author"],
["p", "<pubkey-hex>", "<relay-url>", "editor"]
],
...
}
```
### Context
Clients MAY include a `context` tag, useful when the highlight is a subset of a paragraph and displaying the
surrounding content might be beneficial to give context to the highlight.

## Encrypted Params
If the user wants to keep the input parameters a secret, they can encrypt the `i` and `param` tags with the service provider's 'p' tag and add it to the content field. Add a tag `encrypted` as tags.

## Mailing Lists ## Is this repository a centralizing factor?
The nostr ecosystem is getting large with many different organizations, relays To promote interoperability, we standards that everybody can follow, and we need them to define a **single way of doing each thing** without ever hurting **backwards-compatibility**, and for that purpose there is no way around getting everybody to agree on the same thing and keep a centralized index of these standards. However the fact that such index exists doesn't hurt the decentralization of Nostr. _At any point the central index can be challenged if it is failing to fulfill the needs of the protocol_ and it can migrate to other places and be maintained by other people.
and clients. Following the nips repo on github is becoming more difficult and
noisy. To coordinate on protocol development outside of github, there are
mailing lists where you can work on NIPs before submitting them here:
* [w3c nostr community group][w3-nostr] - [public-nostr@w3.org][mailto-w3] - requires signup It can even fork into multiple and then some clients would go one way, others would go another way, and some clients would adhere to both competing standards. This would hurt the simplicity, openness and interoperability of Nostr a little, but everything would still work in the short term.
* [nostr-protocol google group][nostr-google-group] - [nostr-protocol@googlegroups.com][mailto-google] - no signup required
[w3-nostr]: https://www.w3.org/community/nostr/ There is a list of notable Nostr software developers who have commit access to this repository, but that exists mostly for practical reasons, as by the nature of the thing we're dealing with the repository owner can revoke membership and rewrite history as they want -- and if these actions are unjustified or perceived as bad or evil the community must react.
[mailto-w3]: mailto:public-nostr@w3.org
[nostr-google-group]: https://groups.google.com/g/nostr-protocol ## How this repository works
[mailto-google]: mailto:nostr-protocol@googlegroups.com
Standards may emerge in two ways: the first way is that someone starts doing something, then others copy it; the second way is that someone has an idea of a new standard that could benefit multiple clients and the protocol in general without breaking **backwards-compatibility** and the principle of having **a single way of doing things**, then they write that idea and submit it to this repository, other interested parties read it and give their feedback, then once most people reasonably agree we codify that in a NIP which client and relay developers that are interested in the feature can proceed to implement.
These two ways of standardizing things are supported by this repository. Although the second is preferred, an effort will be made to codify standards emerged outside this repository into NIPs that can be later referenced and easily understood and implemented by others -- but obviously as in any human system discretion may be applied when standards are considered harmful.
