Dear Colleagues and Friends of EXI,

First of all, many thanks to everyone who has contributed comments on  
our first draft specification, and please accept our apologies if you  
have not received an individual reply. We are actively working on some  
comments now, and their involvement and depth have meant that we  
didn't reply as quickly as we would have liked. Please do again take  
time to review these new publications, from your expertise and  
requirements.


The Efficient XML Interchange (EXI) Working Group is pleased to  
publish the Second Public Working Draft of the Efficient XML  
Interchange Format specification. EXI is a very compact representation  
for the XML Information Set, intended for use cases where high  
performance and optimal utilization of computational resources are key.

Title: Efficient XML Interchange (EXI) Format
   Pub URI: http://www.w3.org/TR/exi
   This version URI: http://www.w3.org/TR/2007/WD-exi-20071219

The Working Group agreed to this transition request, subject to vote,  
at its regularly scheduled teleconference on 12th December.


We also published First Public Working Drafts of two documents  
intended to help potential users and implementers to understand and,  
if appropriate, adopt the EXI encoding format:

The two documents are:

1) Title: Efficient XML Interchange (EXI) Primer
   URI shortname: http://www.w3.org/TR/exi-primer

2) Title: Efficient XML Interchange (EXI) Best Practices
   URI shortname: http://www.w3.org/TR/exi-best-practices

The Abstract and Status sections of the Primer and Best Practices  
documents, are bellow.

Sincerely
Greg White and Daniel Vogelheim,
for the EXI Working Group.



Efficient XML Interchange (EXI) Primer
======================================

Abstract
This is a non-normative document intended to provide an easily  
readable technical background on the Efficient XML Interchange (EXI)  
format. It is oriented towards quickly understanding how the EXI  
format can be used in practice and how options can be set to achieve  
specific needs. Section 2. Concepts describes the structure of an EXI  
document and introduces the notions of EXI header, EXI body and EXI  
grammar which are fundamental to the understanding of the EXI format.  
Additional details about data type representation, compression, and  
their interaction with other format features are presented. Finally,  
Section 3. Efficient XML Interchange by Example provides a detailed,  
bit-level description of a schema-less example.


Efficient XML Interchange (EXI) Best Practices
==============================================

Abstract
The purpose of this document is to provide guidelines for the  
interoperable deployment of the Efficient XML Interchange (EXI)  
format. It provides explanations of format features and techniques to  
support interoperable information exchanges using EXI. While intended  
primarily as a practical guide for systems architects and programmers,  
it also presents information suitable for the general reader  
interested in EXI's intended role in the expanding Web.
