### `Optional` authoringAppVersion

authoringAppVersion?: string

String value indicating the authoring App's version number.

### baseMap

baseMap: BasemapJson

The map's basemap layer(s). Layers are drawn based on the index position in the array; The first layer in the array is the first layer drawn, the next layer in the array is drawn on top of it, and so on.

### `Optional` initialState

initialState?: InitialStateJson

The initial state at which to open the map.

### `Optional` mapFloorInfo

mapFloorInfo?: MapFloorInfoJson

Contains floor-awareness information for the map.

### `Optional` mapRangeInfo

mapRangeInfo?: MapRangeInfoJson

Map range information.

### `Optional` operationalLayers

operationalLayers?: OperationalLayerJson[]

Specify an array of table objects.

### `Optional` timeZone

timeZone?: string

TODO: Not yet documented in web map spec, but present in 2.29 web maps generated by Maps SDK 4.28.
