GB/T 16262.3-2025Information technology - Abstract Syntax Notation One (ASN.1) - Part 3: Constraint specification (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting.

This document is Part 3 of GB/T 16262 "Abstract Syntax Notation for Information Technology One (ASN.1)". GB/T 16262 has been published The following parts.

--- Part 1: Basic notation specification;

--- Part 2: Information object specifications;

--- Part 3: Constraint specifications;

--- Part 4: Parameterization of the ASN.1 specification.

This document replaces GB/T 16262.3-2006 "Information Technology Abstract Syntax Notation One (ASN.1) Part 3: Constraint Specification".

Compared with GB/T 16262.3-2006, in addition to structural adjustments and editorial changes, the main technical changes are as follows.

a) Changed the description of parameters in "User-defined constraints" (see 9.3, 9.3 of the 2006 edition);

b) Added the relevant clauses on "table constraints, including component relationship constraints" (see 10.14).

This document is equivalent to ISO /IEC 8824-3:2021 "Information technology Abstract Syntax Notation One (ASN.1) Part 3: Constraints specification". The following minimal editorial changes were made to this document.

--- Added the title of Table 1 (see Chapter 10);

--- Added reference to Appendix B in the text.

Introduction

GB/T 16262 "Abstract Syntax Notation for Information Technology One (ASN.1)" aims to standardize the abstract syntax notation.

Based on ISO /IEC 8824 (all parts), 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.

1 Scope

This document provides a notation for specifying user-defined constraints, table constraints, and content constraints.
