Abstract: Described herein is a computer implemented method for editing an electronic object. The method includes maintaining a local version of the electronic object and a local buffer that includes one or more local deltas. A plurality of server deltas are received from a server system, each server delta being in respect of a remote edit made to the electronic object. The plurality of server deltas are composed to generate a single composed server delta which is then transformed against the one or more local deltas to generate a transformed server delta. The local version of the electronic document is then edited by applying the transformed server delta to the local version of the electronic document.

Abstract: An API for prefetching map data receives a prefetch request for an indicated geographic area from a software application. In response, the API retrieves map data corresponding to the indicated geographic area from a map data provider and stores the map data in a map data cache without causing a digital map based on the map data to be displayed on the display device. The map data cache is accessible to the software application only via the API. Subsequently to storing the map data in the map data cache, the API receives a request to render the digital map from the software application and, in response to the request to render the map image, renders the map image for display on a display device using the map data stored in the map data cache.

Abstract: An electronic device includes a requesting application and a hosting application. When the requesting application requests permission from the hosting application to access a category of data, the device identifies the requesting application and the permission request. The device awaits a user input to determine whether the user will permit the requesting application's request to be granted.
