  3. Known to be incomplete • Need privacy model when presence information of a presentity is composed from information from multiple event packages of same or different presentities • Used in combination with dynamic location information • speed, heading, ... • Need presence package for group membership • “people in a room”, “members of a team”, “passengers on a bus”, ... IETF - SIMPLE

  4. Vehicle Status Information • XML schema for vehicle status and diagnostic information • Based on OBD-II (On Board Diagnostics-II) standard • Standard by car manufacturers for diagnostics • every (US) vehicle since 1996 • Diagnostic Trouble Code (DTC) is a 5 byte code, more details in draft • Vehicle identity using VIN • e.g., 1M8GDM9AXKP042788 IETF - SIMPLE

Example XML <?xml version="1.0" encoding="utf-8" ?> <vehicle-info xmlns="urn:ietf:params:xml:ns:vehicle-info“ entity="sip:44G44444H4444@avis.com" state="full" version="1" > <vehicle-description> <description>4 door sedan</description> <make>Toyota</make> <model>Camry</model> <year>2003</year> </vehicle-description> <vehicle-state> <status>open</status> <movement>moving</movement> <fuel unit="gallon">3.0</fuel> <temperature unit="F">68</temperature> <passengers>3</passengers> <airbags>closed</airbags> </vehicle-state> <vehicle-diagnostics> <obdii DTC="P0120">Throttle Switch Malfunction</obdii> <obdii RTData="EngineCoolantTemp" unit="F">20</obdii> <obdii RTData="VehicleSpeed" unit="Miles">55</obdii> <obdii RTData="EngineRPM" unit="RPM">3257</obdii> </vehicle-diagnostics> </vehicle-info> IETF - SIMPLE

  6. Uses • Could be used to compose presence information of user (RPID) • e.g, vehicle at speed 35mph -> user is driving • Vehicle as a <device> in presence data model? • Vehicle itself is a managed entity (presentity) • vehicle management • Dynamic association of vehicle with multiple users • passengers in car IETF - SIMPLE
