EXI is designed in view to carry out extensive works with the help of W3C’s XML binary characterization. This is one of the efficient XML interchange working groups. The XBC is authorized to find out an alternative form of XML and they succeeded in that venture by developing a substitute format for XML. With respect to the recommendations from XBC, the EXI was first used for measuring, evaluating and comparing the progress of various XML technologies. This evaluation and comparing process are with respect to the measurements proposed by XBC.
In 1989 the Air Transport Association (ATA) adopted Computer Graphics Metafile (CGM) as the format for the interchange of 2-dimensional vector based technical illustrations in maintenance documentation. Both The Boeing Company and United Airlines, along with much of the rest of the industry, use CGM internally to transfer 2-dimensional vector data between diverse systems.
The decision to use CGM, both at the industry level and by individual companies, was made after a review of available open and proprietary formats. Requirements for creation,

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

Abstract
This Working Group Note presents measurement results of various high-performance XML interchange encoding formats and their associated processors, made by the Efficient XML Interchange (EXI) Working Group. The measurements have been conducted following the recommendations of the XML Binary Characterization (XBC) Working Group. In particular, this draft covers measurements of the properties of "compactness", "processing efficiency" and "roundtrip support", as defined by the XBC WG. We start by describing the
