Interactive Stories
-------------------

`draft` `optional`

This NIP introduces `kind:30296` and `kind:30297` as living notes designed to create interactive stories. These notes include `option` tags for navigating to subsequent notes, allowing readers to continue exploring the story. `Kind:30296` serves as starting events for the reader, while `kind:30297` represents individual scenes within the narrative.

The modularity of this approach allows Scenes from multiple authors to be combined into bigger stories. 

### Prologue (kind:30296)

Prologue events are entry points in the story. 

They SHOULD contain `title`, `summary` and `image` to help clients render a preview of the story.

`option` tags include a description for the action button, an address and the relay to find the next scene.

```jsonc
{
  "kind": 30296,
  "content": "<the beginning of the story>",
  "tags": [
    ["d", "<unique identifier>"],
    ["title", "<short title for the prologue>"],
    ["summary", "<summary for preview>"],
    ["image", "<image url for preview>"],

    ["option", "<description>", "<kind:pubkey:d-tag>", "<relay_hint>"],
    ["option", "<description>", "<kind:pubkey:d-tag>", "<relay_hint>"],
    // ...
  ]
}
```

### Scene (kind:30297)

Scenes describe a given point in a story with potential options and SHOULD include an optional `title` tag.

```jsonc
{
  "kind": 30297,
  "content": "<description of the scene>",
  "tags": [
    ["d", "<unique identifier>"],
    ["title", "<short title for this scene>"],

    ["option", "<description>", "<kind:pubkey:d-tag>", "<relay_hint>"],
    ["option", "<description>", "<kind:pubkey:d-tag>", "<relay_hint>"],
    // ...
  ]
}
```

The story concludes when no `option` tags are present.

The `.content` field does not accept markdown.

## Reading State

Kind `30298` stores the latest state of the story. 

The `d` tag of the replaceable event MUST match the root event's id.

The `a` tag points to the latest scene the user has read.

```jsonc
{
  "kind": 30298,
  "tags": [
    // d-tag defines the starting point so that if the user sees an interative post again, the client can find it. 
    ["d", "<kind:pubkey:d-tag>"],

    // cached to simplify preview purposes
    ["title", "<root_event_title>"],
    ["summary", "<root_event_summary>"], 
    ["image", "<image url for preview>"],

    // root with relay hint
    ["A", "<kind:pubkey:d-tag>", "<relay_hint>"], 

    // current scene with relay hint
    ["a", "<kind:pubkey:d-tag>", "<relay_hint>"], 

    // reading status 
    ["status", "<new|reading|done>"]
  ]
}
```
