+## Interactive Rooms and Meetings
+-----
+
+`draft` `optional`
+
+Service providers want to offer Interactive Rooms to the Nostr network in such a way that participants can easily log and query by clients. This NIP describes a general framework to advertise rooms and their associated events.
+
+## Concepts
+
+### Interactive Room (kind:30312)
+
+A special event with `kind:30312` "Interactive Room" defines the configuration and properties of a virtual interactive space. Each room has a unique identifier and can host multiple events/meetings.
+
+```jsonc
+{
+  "kind": 30312,
+  "tags": [
+    ["d", "<unique identifier>"],              // Required: Room identifier
+    ["room", "<name of the room>"],            // Required: Display name
+    ["summary", "<description>"],              // Optional: Room description
+    ["image", "<preview image url>"],          // Optional: Room image
+    ["status", "<open, private, closed>"],     // Required: Room accessibility
+    ["service", "<url>"],                      // Required: URL to access the room
+    ["endpoint", "<url>"],                     // Optional: API endpoint for status/info
+    ["t", "<hashtag>"],                        // Optional: Multiple hashtags allowed
+    ["p", "<pubkey>", "<url>", "<role>", "<proof>"],  // Required: At least one provider
+    ["relays", "<url>", "<url>", /*...*/]     // Optional: Preferred relays
+  ],
+  "content": ""  // Usually empty, may contain additional metadata
+}
+```
+
+Room properties:
+* MUST be either open, private or closed. Closed means the room is not in operation.
+* MAY specify access control policy for private rooms (e.g. invite-only, payment required)
+* MAY persist when not in use
+* MUST have at least one provider with "Host" role
+* MAY have multiple providers with different roles
+Provider roles (p tags):
+* Host: Full room management capabilities
+* Moderator: Room moderation capabilities
+* Speaker: Allowed to present/speak
+* Optional proof field for role verification
+
+### Room Meeting (kind:30313)
+
+A special event with kind:30313 represents a scheduled or ongoing meeting within a room. It MUST reference its parent room using the d tag.
+
+```jsonc
+{
+  "kind": 30313,
+  "tags": [
+    ["d", "<event-unique-identifier>"],        // Required: Event identifier
+    ["a", "30312:<pubkey>:<room-id>", "wss://nostr.example.com"], // Required: Reference to parent room, 'd' from 30312
+    ["title", "<meeting-title>"],              // Required: Meeting title
+    ["summary", "<description>"],              // Optional: Meeting description
+    ["image", "<preview image url>"],          // Optional: Meeting image
+    ["starts", "<unix timestamp>"],            // Required: Start time
+    ["ends", "<unix timestamp>"],              // Optional: End time
+    ["status", "<planned, live, ended>"],      // Required: Meeting status
+    ["total_participants", "<number>"],        // Optional: Total registered
+    ["current_participants", "<number>"],      // Optional: Currently active
+    ["p", "<pubkey>", "<url>", "<role>"],     // Optional: Participant with role
+  ],
+  "content": ""  // Usually empty, may contain additional metadata
+}
+```
+
+Event properties:
+* MUST reference parent room via d tag
+* MUST have a status (planned/live/ended)
+* MUST have a start time
+* MAY track participant counts
+* MAY include participant roles specific to the event
+Event management:
+* Clients SHOULD update event status regularly when live
+* Events without updates for 1 hour MAY be considered ended
+* starts and ends timestamps SHOULD be updated when status changes
+
+Examples
+
+Conference Room (kind:30312)
+
+```jsonc
+{
+  "kind": 30312,
+  "tags": [
+    ["d", "main-conference-room"],
+    ["room", "Main Conference Hall"],
+    ["summary", "Our primary conference space"],
+    ["image", "https://example.com/room.jpg"],
+    ["status", "open"],
+    ["service", "https://meet.example.com/room"],
+    ["endpoint", "https://api.example.com/room"],
+    ["t", "conference"],
+    ["p", "f7234bd4c1394dda46d09f35bd384dd30cc552ad5541990f98844fb06676e9ca", "wss://nostr.example.com/", "Owner"],
+    ["p", "14aeb..8dad4", "wss://provider2.com/", "Moderator"],
+    ["relays", "wss://relay1.com", "wss://relay2.com"]
+  ],
+  "content": ""
+}
+```
+
+Conference Event (kind:30313)
+
+```jsonc
+{
+  "kind": 30313,
+  "tags": [
+    ["d", "annual-meeting-2025"],
+    ["a", "30312:f7234bd4c1394dda46d09f35bd384dd30cc552ad5541990f98844fb06676e9ca:main-conference-room", "wss://nostr.example.com"]
+    ["title", "Annual Company Meeting 2025"],
+    ["summary", "Yearly company-wide meeting"],
+    ["image", "https://example.com/meeting.jpg"],
+    ["starts", "1676262123"],
+    ["ends", "1676269323"],
+    ["status", "live"],
+    ["total_participants", "180"],
+    ["current_participants", "175"],
+    ["p", "91cf9..4e5ca", "wss://provider1.com/", "Speaker"],
+  ],
+  "content": ""
+}
+```
+## Room Presence
+
+New `kind: 10312` provides an event which signals presence of a listener. 
+
+The presence event SHOULD be updated at regular intervals and clients SHOULD filter presence events older than 
+a given time window.
+
+**This kind `10312` is a regular replaceable event, as such presence can only be indicated in one room at a time.**
+
+```json
+{
+  "kind": 10312,
+  "tags": [
+    ["a" , "<room-a-tag>", "<relay-hint>", "root"],
+    ["hand", "1"] // hand raised flag
+  ]
+}
+```
