he IJIS Institute, a nonprofit organization that focuses on
mission-critical information sharing for justice, public safety, and
homeland security, announces the release of a whitepaper on Efficient
eXtensible Markup Language (XML) Interchange (EXI).
The whitepaper, authored by the IJIS Institute’s Technical Advisory
Committee (ITAC), identifies EXI as an emerging technology applicable to
integrated justice and public safety data sharing in the context of the
Justice Reference Architecture (JRA) and the National Information
Exchange Model (NIEM). In essence, EXI is a compact binary
representation of XML that leverages existing XML technologies, such as
schemas, rather than replace them with another format or methodology. It
addresses the increased need for efficient or binary XML resulting from
the increased use of XML.
XML has gained significant use and adoption within many information
technology-related fields; integrated justice and public safety are no
exception. EXI was identified as an efficient XML solution through of
the extensive and open process that was used by the World Wide Web
Consortium (W3C). This W3C effort was performed by the XML Binary
Characterization Working Group and later by the EXI Working Group.
