Efforts specifically addressing data communications interoperability have been the focus of considerable effort within the public safety community. FEMA’s Disaster Management e-Gov initiative and its Disaster Management Interoperability Services (DMIS)9 provide a set of services and software tools to public safety agencies for enabling responders to share information seamlessly between organizations. The Global Justice XML Data Model (GJXDM) and the derivative DHS National Information Exchange Model (NIEM) are intended as data reference models for the exchange of information within the justice and public safety communities.10 Overarching efforts such as the Federal Enterprise Architecture and the e-Authentication e-Gov program also address information sharing and data exchange at the federal level.11

Industry-led efforts at data communications interoperability include the IEEE 1512 Standards Program, oriented to transportation incident management, and the IEEE 1451 Program for Sensor Integration Standards.12 International efforts that span the government, private, and opensource communities include the Organization for the Advancement of Structured Information Standards Emergency Management Technical Committee, developers of the Common Alerting Protocol and the Emergency Data Exchange Language; and the Open GIS Consortium, creators of Geospatial Markup Language and of the Web Map Service and Web Feature Service specifications, among others.

Two significant examples of regional cooperation to provide wireless data interoperability are (1) the CapWIN wireless integrated mobile data communications network involving 41 federal, state, and local agencies serving the U.S. Capital Region (Washington, D.C., Maryland, and Virginia);13 and (2) the Automated Regional Justice Information System (ARJIS) in the greater San Diego region, including San Diego and Imperial Counties in California, used by 71 local, state, and federal agencies to provide wireless data access to critical information in the field.14
