Introduction
GB/T 16262 aims to standardize abstract syntax notation. The compilation of GB/T 16262 is based on ISO /IEC 8824.According to ISO /IEC 8824,
GB/T 16262 is intended to consist of four parts.
--- Part 1.Basic notation specification. The purpose is to define data types, values and constraints on data types.
--- Part 2.Information object specifications. The purpose is to provide information object categories, information objects and information object sets.
Memorization method.
--- Part 3.Constraint specification. The purpose is to provide a notation for specifying user-defined constraints, table constraints and content constraints.
--- Part 4.Parameterization of ASN.1 specifications. The purpose is to define the parameterization notation of ASN.1 specifications.
Information technology Abstract Syntax Notation One (ASN.1)
Part 2.Information object specifications
1 Scope
This document is part of the Abstract Syntax Notation One (ASN.1) and specifies information object classes, information objects, and information object sets.
