Hi -

Given the discussion a the end of the WG session on "different kinds of location", thought that this might be of interest. The following table is how the membership of the Location Interoperability Forum views a taxonomy of location services. Obviously, each type of service has specific requirements for privacy protocols. There is probably also a common set of requirements.
