To: W3C Members <w3c-ac-forum at w3.org>


Dear Advisory Committee Representative,

I am pleased to announce that Efficient XML Interchange (EXI) Format 1.0 has
been published as a W3C Recommendation:

  Efficient XML Interchange (EXI) Format 1.0
  http://www.w3.org/TR/2011/REC-exi-20110310/

The Efficient XML Interchange Format (EXI) is an XML-aware compression
format. It can take advantage of XML Schema information, and, unlike generic
compression systems such as gzip, starts out with knowledge of XML.  EXI is
already seeing adoption in communications between small devices, and is also
being used for large datasets in the sciences, as well as for general XML
and Web usage.  Most applications do not need to be changed in order o
benefit from EXI.

All Members except one who responded to the Call for Review [1] of the
document supported the publication as-is of this specification as a W3C
Recommendation. There was one request for editorial changes to the
references, which were accepted where possible.

In addition, the EXI test suite has been made public from the Working Group
page [2].

Please join us in congratulating the Efficient XML Interchange Working Group
[2] for their achievement.

For Tim Berners-Lee, Director;
Ian Jacobs, Head of W3C Communications.

Disposition of Comments
------------------------

One reviewer requested an update to references to ISO 10646, XML Names,
Relax NG ISO/IEF 1957-2:2008 and SOAP. Of these, ISO 10646 was not yet final
at the time of publication of this Recommendation, but the other changes
were checked and did not affect the format, and so were accepted.

The same commenter also asked about the Primer; work on this document and on
a public FAQ are active and ongoing.

Overall, the W3C Advisory Committee showed strong support for this
specification to be published as a W3C Recommendation.

Abstract
--------

This document is the specification of the Efficient XML Interchange (EXI)
format. EXI is a very compact representation for the Extensible Markup
Language (XML) Information Set that is intended to simultaneously optimize
performance and the utilization of computational resources. The EXI format
uses a hybrid approach drawn from the information and formal language
theories, plus practical techniques verified by measurements, for entropy
encoding XML information. Using a relatively simple algorithm, which is
amenable to fast and compact implementation, and a small set of datatype
representations, it reliably produces efficient encoding of XML event
streams. The grammar production system and format definition of EXI are
presented.
