First Public Working Draft: Efficient XML Interchange (EXI) for JSON

The Efficient XML Interchange Working Group has published a Working Draft of Efficient XML Interchange (EXI) for JSON. The Efficient XML Interchange (EXI) format is a compact representation that simultaneously optimizes performance and the utilization of computational resources. The EXI format was designed to support XML representation. With a relatively small set of transformations it may also be used for JSON, a popular format for exchange of structured data on the Web.
