The Emergency Data Exchange Language (EDXL) is a suite of XML-based messaging standards that facilitate emergency information sharing between government entities and the full range of emergency-related organizations. EDXL standardizes messaging formats for communications between these parties. EDXL was developed as a royalty-free standard by the OASIS International Open Standards Consortium
EDXL was designed to enable information about life-saving resources to be shared across local, state, tribal, national and non-governmental organizations. Implementation of EDXL standards aims to improve the speed and quality of coordinated response activities by allowing the exchange of information in real time.
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 the United States Department of Homeland Security’s Disaster Management E-Gov Initiative.
Implementation of EDXL is promoted by the OASIS Emergency Management Adoption Committee, which was formed in 2009.
The EDXL suite includes:
*EDXL-DE (Distribution Element) OASIS Standard,an XML-based header or wrapper that provides flexible message-distribution for emergency information systems’ data sharing. Messages may be routed by specific recipients, by a geographic area, or by other codes such as incident and agency type (police, fire, etc.). Any content payload can be distributed using the DE, not just EDXL messages.
*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.
*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.
*CAP (Common Alert Protocol) OASIS standard preceding EDXL-DE that is often included in the EDXL family.
Another EDXL specification, 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. 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.
