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

[中文适用范围]： 本建议书/国际标准指定了一个用于从ITU-T X.680 | ISO/IEC 8824-1、ITU-T X.681 | ISO/IEC 8824-2、ITU-T X.682 | ISO/IEC 8824-3和ITU-T X.683 | ISO/IEC 8824-4中定义的类型的值导出传输语法的一组JavaScript对象表示法编码规则（JER）。这些编码规则的规范也隐含了它们也可用于解码。这些在本建议书/国际标准中指定的编码规则：——是在通信时使用的；——适用于以下情况：在选择编码规则时，与使用JSON的应用程序的互操作性是主要关注点；——允许通过增加扩展值来扩展一个抽象语法，如ITU-T X.680 | ISO/IEC 8824-1中所述的所有形式的可扩展性。本建议书/国际标准还指定了JER编码指令的语法和语义、以及它们的分配和组合规则。JER编码指令可以用于控制特定ASN.1类型的JER编码。 [外文原描述]： 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.
