# JavaScript Landmarks Service API

The Landmarks Service API is supported since WRT 1.1.

The Landmarks Service API allows widgets to access and manage information about landmarks and landmark categories. This information is stored in one or more landmark databases on a device. The API is integrated into WRT through the `device` object.

For an overview of the service and the API, see section Accessing and managing information about landmarks.

### Using the Landmarks Service API

To use the Landmarks Service API, your widget must first create a service object for it using the `device.getServiceObject()` method. Use `Service.Landmarks` to identify the service provider and `IDataSource` to identify the supported interface:

    var so = device.getServiceObject("Service.Landmarks", "IDataSource");

This service object can then be used to access the services provided by the API:

- `IDataSource.New()`

- `IDataSource.GetList()`

- `IDataSource.Add()`

- `IDataSource.Delete()`

- `IDataSource.Import()`

- `IDataSource.Export()`

- `IDataSource.Organise()`

- `IDataSource.Cancel()`

### Emulator support

The S60 5th Edition SDK emulator provides full support for the Landmarks Service API.
