From embedded sensors to high-frequency stock trading to everyday mobile Web applications, the race is on for technologists to build the most efficient systems for quickly streaming large sets of data from one device to another. Sometimes the language that data is communicated in can come with high costs in terms of efficiency. Today the Web's most venerable standards body, the Word Wide Web Consortium (W3C), announced official support for a new standardized data format for super-efficient transmission of data.
Efficient XML Interchange, or EXI, is described as a very compact representation of information in XML (extensible markup language). EXI is so efficient that the W3C says it has been found to improve up to 100-fold the performance, network efficiency and power consumption of applications that use XML, including but not limited to consumer mobile apps. It is particularly useful on devices with low memory or low bandwidth.
A Historic Agreement
EXI has been used in commercial contexts for more than seven years, but today's adoption of the format as a formal standard is the culmination years of collaboration between the W3C and 23 different corporate and academic institutions from around the world, including Oracle, IBM, Adobe, Chevron, Stanford University, Boeing, Cannon, France Telecom, Intel, the Web3D Consortium and others.
It's an amazing world where the transmission of large sets of data is costly enough relative to their creation, storage and processing (the price of those has fallen so much already) that industries have a strong incentive to work together to use standards to reduce those data transmission costs substantially.
