Background
EDXL is advanced by the OASIS Emergency Management Technical Committee, 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, through a project sponsored by theComponents
The EDXL suite comprises a number of individual standards. Each standard is elaborated in the following sub-sections:EDXL-DE (Distribution Element)
Overview
EDXL-DE (Distribution Element) OASIS Standard, an XML-based header or wrapper that provides flexible message-distribution for emergency information systems’Purpose
The primary purpose of the Distribution Element is to facilitate the routing of any properly formatted XML emergency message to recipients. 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.Conformance
Although there is anBackground
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) 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.EDXL-HAVE (Hospital Availability Exchange)
Overview
EDXL-HAVE (Hospital Availability Exchange) OASIS Standard, which allows a hospital's status, services, and resources (including bed capacity, emergency department status, and available service coverage) to be communicated.Purpose
EDXL-HAVE specifies an XML document format that allows the communication of the status of a hospital, its services, and its resources. These include bed capacity and availability, emergency department status, available service coverage, and the status of a hospital’s facility and operations.History
In a disaster or emergency situation, there is a need for hospitals to be able to communicate with each other, and with other members of the emergency response community. The ability to exchange data in regard to hospitals’ bed availability, status, services, and capacity enables both hospitals and other emergency agencies to respond to emergencies and disaster situations with greater efficiency and speed. In particular, it will allow emergency dispatchers and managers to make sound logistics decisions - where to route victims, which hospitals have the ability to provide the needed service. Many hospitals have expressed the need for, and indeed are currently using, commercial or self-developed information technology that allows them to publish this information to other hospitals in a region, as well as EOCs, 9-1-1 centers, and EMS responders via a Web-based tool. Systems that are available today do not record or present data in a standardized format, creating a serious barrier to data sharing between hospitals and emergency response groups. Without data standards, parties of various kinds are unable to view data from hospitals in a state or region that use a different system – unless a specialized interface is developed. Alternatively, such officials must get special passwords and toggle between web pages to get a full picture. Other local emergency responders are unable to get the data imported into the emergency IT tools they use (e.g. a 9-1-1 computer-aided dispatch system or an EOC consequence information management system). They too must get a pass word and go to the appropriate web page. This is very inefficient. A uniform data standard will allow different applications and systems to communicate seamlessly. In 2013 the OASIS EM Technical Committee created a sub-committee to revise HAVE. HAVE version 2.0 is under development with draft schema and working documents in place. HAVE version 2.0 is aimed at addressing some shortfalls of the HAVE v1.0 (and the unofficial HAVE v1.1 that evolved informally) and to increase the depth of support for non-hospital facilities (e.g. urgent care clinics, long-term care facilities, temporary facilities).Common Alerting Protocol

Overview
EDXL-SitRep (Situation Reporting) completed the detailed practitioner requirements process in 2008 and was submitted by EIC and the U.S. Department of Homeland Security to OASIS to begin its standards process in March 2009.Purpose
EDXL-SitRep will provide a standard format for sharing general information across the disparate systems of any public or private organization and Emergency Support Function (ESF), about a situation, incident or event and the operational picture of current and required response. The purpose of EDXL-SitRep is to guide more effective preparation, response, management and recovery through seamless summary-level information-sharing before, during and after emergencies and disasters of any scale.EDXL-TEP (Tracking of Emergency Patients)
Overview
EDXL-TEP is an XML messaging standard primarily for exchange of emergency patient and tracking information from patient encounter through hospital admission or release. TEP supports patient tracking across the EMS incident continuum of care, as well as evacuations from hospitals and day to day hospital patient transfers, providing real-time information to responders, emergency management, coordinating organizations and care facilities involved in incidents and the chain of care and transport. The TEP purpose embraces larger Phase II effort objectives for tracking everyone affected by and requiring emergency service or assistance as a result of a mass casualty incident, but is aimed at increased effectiveness of emergency medical services and management, patient tracking, and continued patient care preparedness during emergency care. TEP is driven by cross-profession practitioner needs (Practitioner Steering Group and expanded stakeholder groups), and led by the National Association of State EMS Officials (NASEMSO). It supports select goals of the HHS-Agency for Health and Research Quality (AHRQ) and gaps identified by the Health Information Technology Standards Panel (HITSP).Government support
The U.S. Department of Homeland Security has increasingly embraced the EDXL suite of standards. Official grant guidance requires their use by grantees in information systems funded by the Department.Related standards
