### A Conventional use of `e` and `p` tags within clients. ## Abstract
This NIP describes how to use "e" and "p" tags in text events, especially those that are replies to other text events. It helps clients thread the replies into a tree rooted at the original event.
The following seems to be the conventions that are used by `Branle`, `Damus`, and `more-speech` for referencing ##Positional "e" tags (DEPRECATED)
events and authors when building a reply. These conventions help clients build event threads, and alert authors of >This scheme is in common use; but should be considered deprecated.
replies.
### Definitions: `["e", <event-id> <relay-url>]` as per NIP-01.
* A reply chain is the list of events from the root event to a specific reply.
* A reply thread is the tree of events consisting of all replies beginning at the root.
* An event id is a 32 byte number in lower-case hexidecimal.
### The `e` tag Where:
Used in a text event contains a single event id. ["e", "`hex-number`"]
* No `e` tag: * `<event-id>` is the id of the event being referenced.
This event is not a reply to, nor does it refer to, any other event. * `<relay-url>` is the URL of a recommended relay associated with the reference. Many clients treat this field as optional.
* One `e` tag: ["e",`id`]: **The positions of the "e" tags within the event denote specific meanings as follows**:
The id of the event to which this event is a reply.
* Two `e` tags: ["e",`root-id`], ["e",`reply-id`] * No "e" tag: <br>
'root-id' is the `id` of the event at the root of the reply chain. `reply-id` is the id of the article to which this event is a reply. This event is not a reply to, nor does it refer to, any other event.
* Many `e` tags: ["e",`root-id`] ["e",`mention-id`], ..., ["e",`reply-id`] * One "e" tag: <br>
There may be any number of `mention-ids`. These are the ids of events which may, or may not be in the reply chain. `["e",<id>]`: The id of the event to which this event is a reply.
* Two "e" tags: `["e",<root-id>]`, `["e",<reply-id>]` <br>
`<root-id>` is the id of the event at the root of the reply chain. `<reply-id>` is the id of the article to which this event is a reply.
* Many "e" tags: `["e",<root-id>]` `["e",<mention-id>]`, ..., `["e",<reply-id>]`<br>
There may be any number of `<mention-ids>`. These are the ids of events which may, or may not be in the reply chain.
They are citings from this event. `root-id` and `reply-id` are as above. They are citings from this event. `root-id` and `reply-id` are as above.
### The `p` tag >This scheme is deprecated because it creates ambiguities that are difficult, or impossible to resolve when an event references another but is not a reply.
## Marked "e" tags (PREFERRED)
`["e", <event-id> <relay-url> <marker>]`
Where:
* `<event-id>` is the id of the event being referenced.
* `<relay-url>` is the URL of a recommended relay associated with the reference. It is NOT optional.
* `<marker>` is optional and if present is one of `"reply"` or `"root"`
**The order of marked "e" tags is not relevant.** Those marked with `"reply"` denote the `<reply-id>`. Those marked with `"root"` denote the root id of the reply thread.
>This scheme is preferred because it allows events to mention others without confusing them with `<relay-id>` or `<root-id>`.
## The "p" tag
Used in a text event contains a list of pubkeys used to record who is involved in a reply thread. Used in a text event contains a list of pubkeys used to record who is involved in a reply thread.
When replying to a text event E with `p` tags P, the replying event's `p` tags should contain P as well as the pubkey of the of the event being replied to. When replying to a text event E the reply event's "p" tags should contain all of E's "p" tags as well as the `"pubkey"` of the of the event being replied to.
Example: Given a text event authored by a1 with `p` tags [`p1`, `p2`, `p3`] then the `p` tags of the reply should be [`a1`, `p1`, `p2`, `p3`] Example: Given a text event authored by `a1` with "p" tags [`p1`, `p2`, `p3`] then the "p" tags of the reply should be [`a1`, `p1`, `p2`, `p3`]
