+
+The livechat plugin includes a [Moderation Notes Application](/peertube-plugin-livechat/documentation/user/streamers/moderation_notes).
+The present document describes how this is implemented.
+
+## Basics
+
+This features relies on [XEP-0060: Publish-Subscribe](https://xmpp.org/extensions/xep-0060.html).
+This XEP provide a way to store and retrieve items, and to receive push notifications when an item is created/deleted/modified.
+
+There is a Prosody Module, [mod_pubsub_peertubelivechat](https://github.com/JohnXLivingston/peertube-plugin-livechat/tree/main/prosody-modules/mod_pubsub_peertubelivechat), to implement some specific use of the pubsub mechanism.
+
+This module is also used for [Tasks](/peertube-plugin-livechat/technical/tasks/).
+
+We use the [JID+NodeID addressing](https://xmpp.org/extensions/xep-0060.html#addressing-jidnode) to specify some nodes related to each MUC room.
+The JID is the MUC room JID, the NodeID is functionnality we want to address.
+
+This modules implement the "livechat-notes" node, to handle moderator notes.
+
+The "livechat-notes" node contains one type of objects: Note (XML Namespaces: `urn:peertube-plugin-livechat:note`).
+
+On the front-end, we have the [livechat-converse-notes](https://github.com/JohnXLivingston/peertube-plugin-livechat/tree/main/conversejs/custom/plugins/notes) plugin for ConverseJS.
+
+## Workflow / Unsubscribing
+
+This is basically the same as for [Tasks](/peertube-plugin-livechat/technical/tasks/).
+
+## Items
+
+Here we describes the content of note items.
+
+* Item tag: `note`
+* XML Namespace: `urn:peertube-plugin-livechat:note`
+* item attributes:
+  * `order`: the order of the note in the note list
+* item childs:
+  * `description`: the text content of the note
+  * `note-about`: an optional tag, if the note is associated to a participant
+
+The `note-about` tag, if present, has following structure:
+
+* Item tag: `note-about`
+* XML Namespace: none
+* item attributes:
+  * `jid`: the JID of the occupant
+  * `nick` the nick of the occupant, at time of note creation
+* item childs:
+  * `occupant-id`: see [XEP-0421](https://xmpp.org/extensions/xep-0421.html).
+
