Kinds specify how clients should interpret the meaning of each event and the other fields of each event (e.g. an `"r"` tag may have a meaning in an event of kind 1 and an entirely different meaning in an event of kind 10002). Each NIP may define the meaning of a set of kinds that weren't defined elsewhere. This NIP defines two basic kinds:
- `0`: **metadata**: the `content` is set to a stringified JSON object `{name: <username>, about: <string>, picture: <url, string>}` describing the user who created the event. [Extra metadata fields](24.md#kind-0) may be set. A relay may delete older events once it gets a new one for the same pubkey.
- `0`: **user metadata**: the `content` is set to a stringified JSON object `{name: <username>, about: <string>, picture: <url, string>}` describing the user who created the event. [Extra metadata fields](24.md#kind-0) may be set. A relay may delete older events once it gets a new one for the same pubkey.
- `1`: **text note**: the `content` is set to the **plaintext** content of a note (anything the user wants to say). Content that must be parsed, such as Markdown and HTML, should not be used. Clients should also not parse content as those.
And also a convention for kind ranges that allow for easier experimentation and flexibility of relay implementation:
- for kind `n` such that `1000 <= n < 10000`, events are **regular**, which means they're all expected to be stored by relays.
- for kind `n` such that `1000 <= n < 10000 || 4 <= n < 45 || n == 1 || n == 2`, events are **regular**, which means they're all expected to be stored by relays.
- for kind `n` such that `10000 <= n < 20000 || n == 0 || n == 3`, events are **replaceable**, which means that, for each combination of `pubkey` and `kind`, only the latest event MUST be stored by relays, older versions MAY be discarded.
- for kind `n` such that `20000 <= n < 30000`, events are **ephemeral**, which means they are not expected to be stored by relays.
- for kind `n` such that `30000 <= n < 40000`, events are **parameterized replaceable**, which means that, for each combination of `pubkey`, `kind` and the `d` tag's first value, only the latest event MUST be stored by relays, older versions MAY be discarded.

The `limit` property of a filter is only valid for the initial query and MUST be ignored afterwards. When `limit: n` is present it is assumed that the events returned in the initial query will be the last `n` events ordered by the `created_at`.

`final` `optional`
On events of kind `0` (`metadata`) one can specify the key `"nip05"` with an [internet identifier](https://datatracker.ietf.org/doc/html/rfc5322#section-3.4.1) (an email-like address) as the value. Although there is a link to a very liberal "internet identifier" specification above, NIP-05 assumes the `<local-part>` part will be restricted to the characters `a-z0-9-_.`, case-insensitive.
On events of kind `0` (`user metadata`) one can specify the key `"nip05"` with an [internet identifier](https://datatracker.ietf.org/doc/html/rfc5322#section-3.4.1) (an email-like address) as the value. Although there is a link to a very liberal "internet identifier" specification above, NIP-05 assumes the `<local-part>` part will be restricted to the characters `a-z0-9-_.`, case-insensitive.
Upon seeing that, the client splits the identifier into `<local-part>` and `<domain>` and use these values to make a GET request to `https://<domain>/.well-known/nostr.json?name=<local-part>`.
The result should be a JSON document object with a key `"names"` that should then be a mapping of names to hex formatted public keys. If the public key for the given `<name>` matches the `pubkey` from the `metadata` event, the client then concludes that the given pubkey can indeed be referenced by its identifier.

### Recommendation to Extension Authors
To make sure that the `window.nostr` is available to nostr clients on page load, the authors who create Chromium and Firefox extensions should load their scripts by specifying `"run_at": "document_end"` in the extension's manifest.

======
Protected Events
----------------
`draft` `optional`
When the `"-"` tag is present, that means the event is "protected".
A protected event is an event that can only be published to relays by its author. This is achieved by relays ensuring that the author is [authenticated](42.md) before publishing their own events or by just rejecting events with `["-"]` outright.
The default behavior of a relay MUST be to reject any event that contains `["-"]`.
Relays that want to accept such events MUST first require that the client perform the [NIP-42](42.md) `AUTH` flow and then check if the authenticated client has the same pubkey as the event being published and only accept the event in that case.
## The tag
The tag is a simple tag with a single item: `["-"]`. It may be added to any event.
## Example flow

```
## Why
There are multiple circumstances in which it would be beneficial to prevent the unlimited spreading of an event through all relays imaginable and restrict some to only a certain demographic or to a semi-closed community relay. Even when the information is public it may make sense to keep it compartimentalized across different relays.
It's also possible to create closed access feeds with this when the publisher has some relationship with the relay and trusts the relay to not release their published events to anyone.
Even though it's ultimately impossible to restrict the spread of information on the internet (for example, one of the members of the closed group may want to take an event intended to be restricted and republish it to other relays), most relays would be happy to not facilitate the acts of these so-called "pirates", in respect to the original decision of the author and therefore gladly reject these republish acts if given the means to.
This NIP gives these authors and relays the means to clearly signal when a given event is not intended to be republished by third parties.

Users that want to post into the community, simply tag any Nostr event with the community's `a` tag. Moderators issue an approval event `kind:4550` that links the community with the new post.

# Moderation
# Post Approval by moderators
Anyone may issue an approval event to express their opinion that a post is appropriate for a community. Clients MAY choose which approval events to honor, but SHOULD at least use ones published by the group's defined moderators.
The post-approval event MUST include `a` tags of the communities the moderator is posting into (one or more), the `e` tag of the post and `p` tag of the author of the post (for approval notifications). The event SHOULD also include the stringified `post request` event inside the `.content` ([NIP-18-style](18.md)) and a `k` tag with the original post's event kind to allow filtering of approved posts by kind.
An approval event MUST include one or more community `a` tags, an `e` or `a` tag pointing to the post, and the `p` tag of the author of the post (for approval notifications). `a` tag prefixes can be used to disambiguate between community and replaceable event pointers (community `a` tags always begin with `34550`).
The event SHOULD also include the JSON-stringified `post request` event inside the `.content`, and a `k` tag with the original post's event kind to allow filtering of approved posts by kind.

It's recommended that multiple moderators approve posts to avoid deleting them from the community when a moderator is removed from the owner's list. In case the full list of moderators must be rotated, the new moderator set must sign new approvals for posts in the past or the community will restart. The owner can also periodically copy and re-sign of each moderator's approval events to make sure posts don't disappear with moderators.
Post Approvals of replaceable events can be created in three ways: (i) by tagging the replaceable event as an `e` tag if moderators want to approve each individual change to the replaceable event; (ii) by tagging the replaceable event as an `a` tag if the moderator authorizes the replaceable event author to make changes without additional approvals and (iii) by tagging the replaceable event with both its `e` and `a` tag which empowers clients to display the original and updated versions of the event, with appropriate remarks in the UI. Since relays are instructed to delete old versions of a replaceable event, the `.content` of an `e`-approval MUST have the specific version of the event or Clients might not be able to find that version of the content anywhere.
Approvals of replaceable events can be created in three ways:
Clients SHOULD evaluate any non-`34550:*` `a` tag as posts to be included in all `34550:*` `a` tags.
1. By tagging the replaceable event as an `e` tag if moderators want to approve each individual change to the replaceable event
2. By tagging the replaceable event as an `a` tag if the moderator authorizes the replaceable event author to make changes without additional approvals and
3. By tagging the replaceable event with both its `e` and `a` tag which empowers clients to display the original and updated versions of the event, with appropriate remarks in the UI.
# Displaying
Since relays are instructed to delete old versions of a replaceable event, the `content` of an approval using an `e` tag MUST have the specific version of the event or clients might not be able to find that version of the content anywhere.
Community clients SHOULD display posts that have been approved by at least 1 moderator or by the community owner.
Clients SHOULD evaluate any non-`34550:*` `a` tag as posts to be approved for all `34550:*` `a` tags.
The following filter displays the approved posts.
# Cross-posting
```json
[
"REQ",
"_",
{
"authors": ["<owner-pubkey>", "<moderator1-pubkey>", "<moderator2-pubkey>", "<moderator3-pubkey>", ...],
"kinds": [4550],
"#a": ["34550:<Community event author pubkey>:<d-identifier of the community>"],
}
]
```
Clients MAY hide approvals by blocked moderators at the user's request.
Clients MAY support cross-posting between communities by posting a NIP 18 `kind 6` or `kind 16` repost to one or more communities using `a` tags as described above. The `content` of the repost MUST be the original event, not the approval event.
