## Views and forms

Views: canvas, corner, chip. Canvas forms: landscape, portrait, square, strip.

[Card views, themes and publishing](/docs/cards/). [Browse the gallery](/apps/#cards).

## Data and privacy

Feed: `screenrig.rooms/v1`.

Feed documents carry source attribution. The Player supplies the feed to the card.

Times only: booking titles and names never show.

## Properties

For theme, background, accent and position, see [Common properties](/docs/cards/#common-properties).

Set static properties in `params`. Bind `data` to a project card data key for live values; that document holds only dynamic properties. Without a data key, put the complete configuration in `params`. Nested rows describe the contents of their parent property.

### Static properties

| Name | Type | Default | Values and limits | Description |
| --- | --- | --- | --- | --- |
| `title` | string | `"Study rooms"` | maxLength: `40` |  |
| `minFreeMinutes` | integer | `20` | minimum: `0`; maximum: `240` | A room free for less than this reads as booked soon, not free. |
| `opensAt` | string | `""` | maxLength: `5` | When the library opens, HH:MM in the screen's zone. Empty: always open. |
| `closesAt` | string | `""` | maxLength: `5` | When the library closes, HH:MM. Rooms read free until then; empty: until the day's end. |
| `sort` | string | `"free"` | `"free"`, `"feed"` | free puts the room free the longest first; feed keeps the order given. |
| `showSeats` | boolean | `true` |  |  |
| `staleMinutes` | integer | `10` | minimum: `1`; maximum: `1440` |  |
| `hour12` | boolean | `false` |  |  |
| `timeZone` | string, null | `null` |  |  |

### Dynamic properties

| Name | Type | Default | Values and limits | Description |
| --- | --- | --- | --- | --- |
| `rooms` | array | `[]` | maxItems: `60` | The rooms. A feed (screenrig.rooms/v1) wins when present; the data store supplies the same rows otherwise. |
| `rooms[].name` | string |  | minLength: `1`; maxLength: `40`; Required |  |
| `rooms[].floor` | string |  | maxLength: `24` | Level 2. |
| `rooms[].capacity` | integer |  | minimum: `1`; maximum: `500` | Seats. |
| `rooms[].events` | array |  | maxItems: `60` | The room's bookings. Titles and names never show. |
| `rooms[].events[].start` | string |  | maxLength: `32`; Required | ISO 8601; with an offset or wall time in the screen's zone. |
| `rooms[].events[].end` | string |  | maxLength: `32` | Without it a booking lasts an hour. |
| `updated` | string | `""` | maxLength: `32` | When the bookings were read, ISO 8601 (data store only; a feed carries fetchedAt). |

```console
curl --request PUT "https://api.screenrig.ai/api/card-data/study-rooms-main" \
  --header "Authorization: Bearer $SCREENRIG_TOKEN" \
  --header "ScreenRig-Project: $SCREENRIG_PROJECT" \
