Dynamic Extensions to the Presence Information Data Format
Location Object (PIDF-LO)
Abstract
The Geopriv Location Object introduced by the Presence Information
Data Format - Location Object (PIDF-LO), RFC 4119, defines a basic
XML format for carrying geographical information of a presentity.
This document defines PIDF-LO extensions to convey information about
moving objects. Elements are defined that enable expression of
spatial orientation, speed, and heading of the presentity.

1. Introduction
The Presence Information Data Format - Location Object (PIDF-LO) (see
RFC 4119 [RFC4119]) provides geographical location of a presentity.
This corresponds to a physical location at a given instance of time.
RFC 5491 [RFC5491] extends PIDF-LO and provides additional guidelines
to implementers.
This document extends PIDF-LO to convey spatial orientation, speed,
and heading of a presentity. The addition of rate-of-change
information to the PIDF-LO enables a range of use cases. These use
cases either use dynamic information directly or use that information

for smoother tracking of a position over time. For example, an
application that continuously tracks a presentity could use velocity
information to extrapolate positions in between times that location
information is measured. A shipping company could directly use speed
to monitor delivery truck speed to ensure speed limits are observed.
