## Definitions

### `dev.sensorthings.thing`

**Type**: `record`

A physical object (station, platform, device) capable of hosting sensors.

**Key**: `any`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `name` | `string` | Yes |  |
| `location` | `ref` → `#geoPoint` | No | Nominal/static location of the Thing. For mobile platforms, this is the deployment position (e.g. mooring point); time-varying position is recorded via position observations. |
| `createdAt` | `string` (datetime) | Yes |  |
| `properties` | `unknown` | No | Open metadata object (manufacturer, model, serial number, deployment date, etc.) |
| `description` | `string` | No |  |

### `dev.sensorthings.thing#geoPoint`

**Type**: `object`

WGS84 point. Coordinates as integers: latE7 = lat × 1e7, lonE7 = lon × 1e7. Altitude in millimetres. To be replaced with ATGeo community type when available.

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `altMm` | `integer` | No | Altitude in mm above WGS84 ellipsoid |
| `latE7` | `integer` | Yes |  |
| `lonE7` | `integer` | Yes |  |
