                Protocol (CAP)

               Presented 26 September 2008 at
Joint Implementation-coordination Meeting on the GTS-WIS MTN
            and Meeting of the CBS Expert Team on

        Today's Public Warning Patchwork

    Every government has various public warning systems:
     Weather by news wire, by radio, by television,
       by e-mail, by SMS text on cell phones ...
     Earthquakes by e-mail, by news wire, by Web
       sites, by pagers, by telephone calls ...
     Amber alerts by highway signs, by fax,
       by phone trees, by Web sites, by police radio...
     Civil defense by television, by radio, by sirens,
       by police with bullhorns...
     And on, and on ...

      The New Strategy for Public Warning


   Governments now realize it makes no sense
    to build separate public warning systems
    for each particular type of emergency and
    for each particular communications medium
   Instead, efficiency and effectiveness argue
    for addressing public warning requirements
    with all-media coverage across all-hazards
    through the use of common standards

              A Case in Point:
  The Common Alerting Protocol (CAP) Standard

 CAP is a standard message format especially designed
 for All-Media, All-Hazard, communications:
   over any and all media (television, radio, telephone,
   fax, highway signs, e-mail, Web sites, RSS "Blogs", ...)
   about any kind of hazard situation (Weather, Fires,
   Earthquakes, Volcanoes, Landslides, Child Abductions,
   Disease Outbreaks, Air Quality Warnings, Beach
   Closings, Transportation Problems, Power Outages, ...)
   to anyone: the public at large; designated groups
   (civic authority, responders, etc.); or specific people

Google Earth example using open standards
                Structure of a CAP Alert

   CAP Alert messages
     contain:
    Text values for human
     readers, e.g., "headline",
     "description",
     "instruction",
     "area description", etc.
    Coded values useful for
     filtering, routing, and
     automated translation
     to human languages

     The Content Standard for Alerts: CAP
         Filtering and Routing Criteria

             Date/Time
             Geographic Area
               (polygon, circle, geographic codes)
             Status
               (Actual, Exercise, System, Test)
             Scope
               (Public, Restricted, Private)
             Type
               (Alert, Update, Cancel, Ack, Error)

     The Content Standard for Alerts: CAP
         Filtering and Routing Criteria

      Event Categories
        (Geo, Met, Safety, Security, Rescue,
        Fire, Health, Env, Transport, Infra, Other)
      Urgency: Timeframe for responsive action
        (Immediate, Expected, Future, Past, Unknown)
      Severity: Level of threat to life or property
        (Extreme, Severe, Moderate, Minor, Unknown)
      Certainty: Probability of occurrence
        (Very Likely, Likely, Possible, Unlikely, Unknown)

                    The CAP Standard (X.1303)

        Compatible with legacy as well as newer
         transports (WMO messages, news wires,
         digital TV, Web Services, ...)
        Flexible geographic targeting
        Phased and delayed effective time, expiration
        Message update and cancellation features
        May include inline digital images and audio
        Approved by OASIS as Version 1.1 (2005)
        Adopted as ITU Recommendation X.1303 (2006)
        Significant uptake, many implementations

          ITU Resolution 136 (Antalya, 2006)


    "The Plenipotentiary Conference [...] resolves
    to instruct the Directors of the Bureaux [...]
    to promote implementation by appropriate
    alerting authorities of the international content
    standard for all-media public warning,
    in concert with ongoing development of
    guidelines by all ITU Sectors for application
    to all disaster and emergency situations"

          NEWS -- Federal Communications Commission --May 31, 2007
             FCC TAKES ACTION TO FURTHER STRENGTHEN
                  NATION'S EMERGENCY ALERT SYSTEM


"Washington, D.C. - The Federal Communications Commission
today adopted [an Order that] requires [Emergency Alert
System (EAS)] participants to accept messages using
Common Alerting Protocol (CAP) [...]
        The use of CAP will help to ensure the efficient and
rapid transmission of EAS alerts [...] in a variety of formats
(including text, audio and video) and via different means
(broadcast, cable, satellite, and other networks) [...]
        In addition, the Order expands the EAS system by
requiring participation by wireline video providers."
