  • [Wikipedia CAP] 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. Individuals can receive standardized alerts 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 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 Commercial Mobile Alert System (CMAS), 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. [Wikipedia EDXL] EDXL is advanced by the OASIS Emergency Management Technical Committee, [2] a group that was formed in 2003 and remains open to participation from organizations, agencies, and individuals from around the world. EDXL is based on detailed requirements and draft specifications provided to OASIS by emergency practitioners, with support from the Emergency Interoperability Consortium, [3] through a project sponsored by the United States Department of Homeland Security’s Disaster Management E-Gov Initiative. EDXL-DE was approved as an OASIS Standard in 2006; EDXL-RM and –HAVE were approved as OASIS Standards in 2008. Implementation of EDXL is promoted by the OASIS Emergency Management Adoption Committee, which was formed in 2009. Background The Disaster Management eGov Initiative of the Department of Homeland Security (DHS) determined in 2004 to launch a project to develop interagency emergency data communications standards. It called together a group of national emergency response practitioner leaders and sought their guidance on requirements for such standards. In June, 2004 the first such meeting identified the need for a common distribution element for all emergency messages. Subsequent meetings of a Standards Working Group developed detailed requirements and a draft specification for such a distribution element (DE). During the same period the DM Initiative was forming a partnership with industry members of the Emergency Interoperability Consortium (EIC) to cooperate in the development of emergency standards. EIC had been a leading sponsor of the Common Alerting Protocol (CAP). Both organizations desired to develop an expanded family of data formats for exchanging operational information beyond warning. EIC members participated in the development of the DE, and in the broader design of the design of a process for the development of additional standards. This was named Emergency Data Exchange Language (EDXL). The goal of the EDXL project is to facilitate emergency information sharing and data exchange across the local, state, tribal, national and non-governmental organizations of different professions that provide emergency response and management services. EDXL will accomplish this goal by focusing on the standardization of specific messages (messaging interfaces) to facilitate emergency communication and coordination particularly when more than one profession is involved. It is not just an "emergency management" domain exercise. It is a national effort including a diverse and representative group of local, state and federal emergency response organizations and professionals, following a multi-step process. Just as a data-focused effort targets shared data elements, the EDXL process looks for shared message needs, which are common across a broad number of organizations. The objective is to rapidly deliver implementable standard messages, in an incremental fashion, directly to emergency response agencies in the trenches, providing seamless communication and coordination supporting each particular process. The effort first addresses the most urgent needs and proceeds to subsequent message sets in a prioritized fashion. The goal is to incrementally develop and deliver standards. EDXL is intended as a suite of emergency data message types including resource queries and requests, situation status, message routing instructions and the like, needed in the context of cross-disciplinary, cross-jurisdictional communications related to emergency response. The priorities and requirements are created by the DM EDXL Standards Working Group (SWG) which is a formalized group of emergency response practitioners, technical experts, and industry. The draft DE specification was trialed by a number of EIC members starting in October, 2004. In November, 2004, EIC formally submitted the draft to the OASIS Emergency Management Technical Committee for standardization. EDXL-RM (Resource Messaging) Overview EDXL-RM (Resource Message) [5] OASIS Standard, which describes a suite of standard messages for sharing data among information systems that coordinate requests for emergency equipment, supplies, and people. Purpose The primary purpose of the Emergency Data Exchange Language Resource Messaging (EDXL-RM) Specification is to provide a set of standard formats for XML emergency response messages. These Resource Messages are specifically designed as payloads of Emergency Data Exchange Language Distribution Element- (EDXL-DE)-routed messages. Together EDXL-DE and EDXL-RM are intended to expedite all activities associated with resources needed to respond and adapt to emergency incidents. The Distribution Element may be thought of as a "container". It provides the information to route "payload" message sets (such as Alerts or Resource Messages), by including key routing information such as distribution type, geography, incident, and sender/recipient IDs. The Resource Message is constrained to the set of Resource Message Types contained in this specification. The Resource Message is intended to be the payload or one of the payloads of the Distribution Element which contains it. History Disaster Management (DM) is a communications program in the Department of Homeland Security’s (DHS) Office for Interoperability and Compatibility (OIC) and managed by the Science and Technology (S&T) Directorate. The program was initiated as one of the President’s e-government initiatives. DM’s mission is to serve as the program within the Federal Government to help local, tribal, state, and federal public safety and emergency response agencies improve public safety response through more effective and efficient interoperable data sharing. The DHS DM program sponsors a Practitioner Steering Group (PSG). The DM Practitioner Steering Group (PSG) governance was formalized following publication of the EDXL Distribution Element. It plays a key role in the direction, prioritization, definition, and execution of the DHS-DM program. The group is composed of representatives of major emergency response associations, setting priorities and providing recommendations regarding messaging standards development as well as the other facets of the DM program. The PSG specified messaging standards-based systems interoperability as the top priority for the DHS Disaster Management program. The EDXL Resource Messaging Specification effort was identified as the top priority standard by this group following the EDXL-DE. The requirements and specification effort was initiated by this group in partnership with industry members of the Emergency Interoperability Consortium (EIC) in a Standards Working Group (SWG). That group developed a draft specification which was submitted to the OASIS Emergency Management Technical Committee to begin work on this EDXL-RM specification. The process remained the same as with the EDXL-DE specification with the exception that the Technical Committee requested that the initial candidate specification submitted by the expert group be recast as a formal Requirements Document according to a template that the Technical Committee provided to the expert group. The candidate specification was then resubmitted along with this requested requirements document.
