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

发布日期：2018-10

标准范围

ISO/IEC 8825-8:20 18本推荐国际标准指定了一组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，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。本推荐国际标准规定的编码规则:-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。该推荐性国际标准还规定了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ASN.1类型的JER编码。

ISO/IEC 8825-8:2018 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, 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 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, and the rules for their assignment and combination. JER encoding instructions can be used to control the JER encoding for specific ASN.1 types.
