W3C Invites Implementations of Efficient XML Interchange (EXI) Format 1.0

The Efficient XML Interchange Working Group invites implementation of the Candidate Recommendation of Efficient XML Interchange (EXI) Format 1.0. This document is the specification of the Efficient XML Interchange (EXI) format, 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 amenable to fast and compact implementation, and a small set of datatype representations, it reliably produces efficient encodings of XML event streams. The group also updated the EXI Primer. Read the group's interoperability test plan and learn more about the Extensible Markup Language (XML) Activity.
