Scope:

This Recommendation | International Standard specifies a set of JavaScript Object Notation Encoding Rules (JER) that may be used to derive a transfer syntax for values of types defined in Rec. ITU-T X.680 | ISO/IEC 8824-1, Rec. ITU-T X.681 | ISO/IEC 8824-2, Rec. ITU-T X.682 | ISO/IEC 8824-3 and Rec. ITU-T X.683 | ISO/IEC 8824-4. It is implicit inthe specification of these encoding rules that they are also to be used for decoding.

The encoding rules specified in this Recommendation | International Standard:

  • are used at the time of communication;
  • are intended for use in circumstances where interoperability with applications using JSON is the major concern in the choice of encoding rules;
  • allow the extension of an abstract syntax by addition of extra values for all forms of extensibility described in Rec. ITU-T X.680 | ISO/IEC 8824-1.

This Recommendation | International Standard also specifies the syntax and semantics of JER encoding instructions, as well as the rules for their assignment and combination. JER encoding instructions can be used to control JER encoding for specific Abstract Syntax Notation One (ASN.1) types.

Project need:

To align Canadian requirements with those of international standards in the ICT subject area (adoption of new standard. This proposed New Standard is being developed at the request of P123 Technical Committee on Information Technology. It will provide the industry with the latest requirements in the field of ICT, including cybersecurity and software. This will meet the strategic needs of the following key interests: a) ensuring that the latest innovative/technology/safety features are available for users.
