中文名称：信息技术 ASN.1编码规则 第8部分：JavaScript对象符号编码规则（JER）规范

英文名称：Information technology — ASN.1 encoding rules — Part 8: Specification of JavaScript Object Notation Encoding Rules (JER)

发布日期：2021-06

标准范围

本文档指定了一组JavaScript对象符号编码规则（JER），可用于导出Rec中定义的类型的值的传输语法。ITU-T X.680 ISO/IEC 8824-1，建议。ITU-T X.681 ISO/IEC 8824-2，建议。ITU-T X.682 ISO/IEC 8824-3和建议。ITU-T X.683 ISO/IEC 8824-4。在这些编码规则的规范中隐含的是，它们也将用于解码。本文档中指定的编码规则:-在通信时使用；-旨在用于与使用JSON的应用程序的互操作性是选择编码规则的主要关注点的情况下；-允许通过为Rec中描述的所有形式的可扩展性添加额外值来扩展抽象语法。ITU-T X.680 ISO/IEC 8824？1.该文档还指定了JER编码指令的语法和语义，以及它们的赋值和组合规则。JER编码指令可用于控制特定抽象语法符号一（ASN.1）类型的JER编码。

This document 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 in the specification of these encoding rules that they are also to be used for decoding.
The encoding rules specified in this document:
– 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 document 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.
