Technology Overview
Binary XML Standard
ECMAScript for XML

A key benefit of AgileDelta's Efficient XML is the knowledge that you are using software based on open standards.

The World Wide Web Consortium (W3C) has adopted our Efficient XML Interchange (EXI) format as the global web standard for efficient, interoperable exchange of XML data across platforms and devices. AgileDelta is editor of the standard and worked closely with the W3C to define all the elements of the standard. Our Efficient XML products include full support for the EXI standard.

Below is a brief history of the development of the Efficient XML Interchange standard.

  AUG 2003 AgileDelta proposes W3C create the standard, specifying associated theories, benefits and requirements.
MAR 2004 W3C forms XML Binary Characterization (XBC) working group to review use cases, collect requirements and determine feasibility.
MAR 2005 W3C decides to create the standard and specifies the minimum requirements.
NOV 2005 W3C forms Efficient XML Interchange (EXI) working group to create the standard.
NOV 2006 W3C selects AgileDelta's Efficient XML as the basis of the standard after completing a comprehensive analysis and benchmarking of candidate technologies.
JUL 2007 W3C publishes first draft Efficient XML Interchange standard selecting AgileDelta as editor.
DEC 2007 W3C publishes first working drafts of the Efficient XML Interchange (EXI) Best Practices and EXI Primer. The Best Practices document provides guidelines for interoperability and the Primer provides a quick way to understand the underlying technology of EXI, developed by AgileDelta.
DEC 2007 W3C publishes second draft Efficient XML Interchange standard.
MAR 2008 W3C publishes third draft Efficient XML Interchange standard.
JUL 2008 W3C publishes forth draft Efficient XML Interchange standard.
SEP 2008 W3C publishes Last Call Efficient XML Interchange standard requesting final comments.
NOV 2008 Last Call for comments ends. W3C addresses all comments and begins preparing Candidate Recommendation.
APR 2009 W3C publishes Efficient XML Interchange Evaluation measuring compactness, decoding speed, encoding speed and full requirements coverage of AgileDelta's Efficient XML implementation.
DEC 2009 W3C publishes Candidate Recommendation Efficient XML Interchange standard indicating it is stable and ready for broad implementation.
MAR 2010 Final comment period for implementers ends. W3C addresses all comments and begins interoperability testing.
DEC 2010 W3C completes interoperability testing showing 100% interoperability across over 3000 test cases and 3 independent implementations.
JAN 2011 W3C publishes Proposed Recommendation of Efficient XML Interchange standard for final review by W3C Advisory Committee.
FEB 2011 W3C advisory committee approves Proposed Recommendation indicating Efficient XML Interchange standard is completed and ready for publication.
MAR 2011 W3C publishes final version of Efficient XML Interchange standard.

AgileDelta is a strong believer in open standards and has contributed an extensive amount of time and effort developing use cases, requirements, designs, analysis, technical proposals, and software to support the W3C's efforts in this area. We would love to hear your thoughts and feedback on the standard.
