The World Wide Web Consortium (W3C), the standards body for the Web, has declared that it will officially support Efficient XML Interchange (EXI). Essentially, EXI provides a more compact way to represent XML data. As a result, it can improve the performance, network efficiency and power consumption of applications that use XML by up to 100 times.
More than 23 different organizations worked together to create the standard, including Oracle, IBM, Adobe, Chevron, Stanford University, Boeing, Intel and, of course, W3C.
