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 planned to consist of 4 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 1.Basic notation specifications
1 Scope
This document provides a standard notation called Abstract Syntax Notation One (ASN.1) for defining data types, values, and data classes.
Type constraints.
This document.
---Defines some simple types and their tags, and also specifies the notation for referencing these types and specifying the values of these types;
---Defines a mechanism for constructing new types from multiple basic types, and also specifies how to define these types and assign tags and rules to them
Notation for values of these types;
---Defines the character set used within ASN.1 (by reference to other standards).
ASN.1 can be used when it is necessary to define the abstract syntax of information.
ASN.1 notation is referenced by other standards that define encoding rules for ASN.1 types.
