The Common Alerting Protocol (CAP) is an XML-based data format for exchanging public warnings and emergencies between alerting technologies. CAP allows a warning message to be consistently disseminated simultaneously over many warning systems to many applications. CAP increases warning effectiveness and simplifies the task of activating a warning for responsible officials. Standardized alerts can be received from many sources and configure their applications to process and respond to the alerts as desired. Alerts from the Department of Homeland Security, the Department of the Interior's United States Geological Survey, and the United States Department of Commerce's National Oceanic and Atmospheric Administration (NOAA), and state and local government agencies can all be received in the same format, by the same application. That application can, for example, sound different alarms based on the information received. By normalizing alert data across threats, jurisdictions, and warning systems, CAP also can be used to detect trends and patterns in warning activity, such as trends that might indicate an undetected hazard or hostile act. From a procedural perspective, CAP reinforces a research-based template for effective warning message content and structure. The CAP data structure is backward-compatible with existing alert formats including the Specific Area Message Encoding (SAME) used in Weatheradio and the broadcast Emergency Alert System as well as new technology such as the Wireless Emergency Alerts (WEA), while adding capabilities including: *Flexible geographic targeting using latitude/longitude “boxes” and other geospatial representations in three dimensions; *Multilingual and multi-audience messaging; *Phased and delayed effective times and expirations; *Enhanced message update and cancellation features; *Template support for framing complete and effective warning messages; *Digital encryption and signature capability; *Facility for digital images, audio, and video. ==Background== The U.S. National Science and Technology Council (NSTC) November 2000 report on “Effective Disaster Warnings” recommended that “a standard method should be developed to collect and relay instantaneously and automatically all types of hazard warnings and reports locally, regionally and nationally for input into a wide variety of dissemination systems”.〔http://www.sdr.gov/NDIS_rev_Oct27.pdf〕 In 2001 an international, independent group of over 120 emergency managers convened online by California emergency telecommunications expert Art Botterell began specifying and prototyping the Common Alerting Protocol data structure based on the recommendations of the NSTC report. The project was embraced by the non-profit Partnership for Public Warning and a number of international warning system vendors.〔http://www.ppw.us〕 A series of field trials and long-term demonstration projects during 2002-03 led to the submission of a draft CAP specification to the OASIS standards process for formalization. The CAP 1.0 specification was approved by OASIS in April 2004. Based on experience with CAP 1.0, the OASIS Emergency Management Technical Committee adopted an updated CAP 1.1 specification in October 2005.〔http://www.oasis-open.org/committees/emergency〕〔http://www.oasis-open.org/committees/download.php/14759/emergency-CAPv1.1.pdf〕 At a meeting in Geneva in October 2006 the CAP 1.1 specification was taken under consideration by the International Telecommunications Union for adoption as an ITU recommendation. The latest CAP specification version 1.2 is available since July 2010 at the OASIS Web site.〔http://docs.oasis-open.org/emergency/cap/v1.2/CAP-v1.2-os.pdf〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Common Alerting Protocol」の詳細全文を読む スポンサード リンク
