This specification is limited to providing a scripting API for retrieving geographic position information associated with a hosting device. The geographic position information is provided in terms of World Geodetic System coordinates [WGS84]. It does not include providing a markup language of any kind, nor does not include defining a new URL scheme for building URLs that identify geographic locations.

When an error occur, the second argument of the watchPosition() or getCurrentPosition() method gets called with a GeolocationPositionError error, which can help you figure out what might have gone wrong.

An end-user will generally give express permission through a user interface, which usually present a range of permission lifetimes that the end-user can choose from. The choice of lifetimes vary across user agents, but they are typically time-based (e.g., "a day"), or until browser is closed, or the user might even be given the choice for the permission to be granted indefinitely. The permission lifetimes dictate how long a user agent grants a permission before that permission is automatically reverted back to its default permission state, prompting the end-user to make a new choice upon subsequent use.
