Further, because it is XML, it already works with the myriad XML tools in the market, and it plugs into the Web services format, said Ian Jacobs, the W3C’s director of communications.

Schneider said EXI has seen an uptake in automotive, financial and media industries, and has been adopted as part of the Smart Energy Profile 2.0, created by the ZigBee Alliance as part of a more efficient energy grid initiative. So, using EXI, information can be exchanged between smart meters in an electric grid, or between energy-smart appliances and homeowners or the utility company.

According to Jacobs, EXI “extends XML into new areas it couldn’t go before. XML is again relevant with the latest technology.”
