======
Comment
-------
`draft` `optional`
A comment is a threading note always scoped to a root event or an [`I`-tag](73.md).
It uses `kind:1111` with plaintext `.content` (no HTML, Markdown, or other formatting).
Comments MUST point to the root scope using uppercase tag names (e.g. `K`, `E`, `A` or `I`)
and MUST point to the parent item with lowercase ones (e.g. `k`, `e`, `a` or `i`).
Comments MUST point to the authors when one is available (i.e. tagging a nostr event). `P` for the root scope
and `p` for the author of the parent item.
```jsonc
{
kind: 1111,
content: '<comment>',
tags: [
// root scope: event addresses, event ids, or I-tags.
["<A, E, I>", "<address, id or I-value>", "<relay or web page hint>", "<root event's pubkey, if an E tag>"],
// the root item kind
["K", "<root kind>"],
// pubkey of the author of the root scope event
["P", "<root-pubkey>", "relay-url-hint"],
// parent item: event addresses, event ids, or i-tags.
["<a, e, i>", "<address, id or i-value>", "<relay or web page hint>", "<parent event's pubkey, if an e tag>"],
// parent item kind
["k", "<parent comment kind>"],
// parent item pubkey
["p", "<parent-pubkey>", "relay-url-hint"]
]
// other fields
}
```
Tags `K` and `k` MUST be present to define the event kind of the root and the parent items.
`I` and `i` tags create scopes for hashtags, geohashes, URLs, and other external identifiers.
The possible values for `i` tags – and `k` tags, when related to an extenal identity – are listed on [NIP-73](73.md).
Their uppercase versions use the same type of values but relate to the root item instead of the parent one.
`q` tags MAY be used when citing events in the `.content` with [NIP-21](21.md).
```json
["q", "<event-id> or <event-address>", "<relay-url>", "<pubkey-if-a-regular-event>"]
```
`p` tags SHOULD be used when mentioning pubkeys in the `.content` with [NIP-21](21.md).
Comments MUST NOT be used to reply to kind 1 notes. [NIP-10](10.md) should instead be followed.
## Examples
A comment on a blog post looks like this:
```jsonc
{
kind: 1111,
content: 'Great blog post!',
tags: [
// top-level comments scope to event addresses or ids
["A", "30023:3c9849383bdea883b0bd16fece1ed36d37e37cdde3ce43b17ea4e9192ec11289:f9347ca7", "wss://example.relay"],
// the root kind
["K", "30023"],
// author of root event
["P", "3c9849383bdea883b0bd16fece1ed36d37e37cdde3ce43b17ea4e9192ec11289", "wss://example.relay"]
// the parent event address (same as root for top-level comments)
["a", "30023:3c9849383bdea883b0bd16fece1ed36d37e37cdde3ce43b17ea4e9192ec11289:f9347ca7", "wss://example.relay"],
// when the parent event is replaceable or addressable, also include an `e` tag referencing its id
["e", "5b4fc7fed15672fefe65d2426f67197b71ccc82aa0cc8a9e94f683eb78e07651", "wss://example.relay"],
// the parent event kind
["k", "30023"],
// author of the parent event
["p", "3c9849383bdea883b0bd16fece1ed36d37e37cdde3ce43b17ea4e9192ec11289", "wss://example.relay"]
]
// other fields
}
```
A comment on a [NIP-94](94.md) file looks like this:
```jsonc

["P", "3721e07b079525289877c366ccab47112bdff3d1b44758ca333feb2dbbbbe5bb"],

["p", "3721e07b079525289877c366ccab47112bdff3d1b44758ca333feb2dbbbbe5bb"]

// podcast episode type
["K", "podcast:item:guid"],
