OASIS is pleased to announce that Emergency Data Exchange Language (EDXL) Hospital AVailability Exchange (HAVE) Version 2.0 from the OASIS Emergency Management TC [1] has been approved as an OASIS Committee Specification. 

EDXL-HAVE (HAVE) is an XML messaging standard primarily for exchange of information related to health facilities in the context of emergency management. HAVE supports sharing information about facility services, bed counts, operations, capacities, and resource needs so first responders, emergency managers, coordinating organizations, hospitals, care facilities, and the health community can provide each other with a coherent view of the health system.

This Committee Specification is an OASIS deliverable, completed and approved by the TC and fully ready for testing and implementation.

The prose specifications and related files are available here:
