Standard Digitalization - Part 2: Reference Architecture Model
1 Scope
This document establishes the overall framework for the reference architecture model of standard digitalization, provides guidance and recommendations regarding capability characteristics, lifecycle, application levels, etc., and presents relevant information.
This document applies to various entities such as individuals, organizations, and institutions for:
a)Planning and organizing standardization activities;
b)Identifying the digital capability levels of standard content;
c)Clarifying the basic conditions required for conducting activities at each lifecycle stage;
d) Referring to and providing standard digitalization application services at different levels.

3 Terms and Definitions
For the purposes of this document, the terms and definitions given in GB/T 20000.1, GB/T 48000.1 and the following apply.
3.1 standard digitalization
A series of activities that utilize digital technology to empower the content and lifecycle process of standards, enabling the rules embedded in standards to be read, transmitted, and used by machines in digital form.
[SOURCE: GB/T 48000.1—2025, 3.4]

[SOURCE: ISO/IEC 20924:2024, 3.1.26]
3.3 standard information model
A formal model composed of standard information units, expressing normalized data objects of digital standards and their dependency relationships.
[SOURCE: GB/T 45508—2025, 3.1.4, modified]
3.4 standard information unit
A reusable, independent unit with a standardized structure used to express standard information.
[NOTE: Includes textual information units, semantic information units, functional information units, etc.]
4 Abbreviations
The following abbreviations apply to this document.
API: Application Program Interface
SIM: Standard Information Model
SIU: Standard Information Unit
XML: Extensible Markup Language
5 Overall Framework
The reference architecture for standard digitalization describes the capability levels, processes, and application objects involved in standard digitalization activities from three dimensions: Capability Characteristics, Lifecycle, and Application Levels. The three dimensions in the model correspond respectively to the three main aspects outlined in GB/T 48000.1—2025: Content Digitalization, Process Digitalization, and Application Digitalization. The overall framework of the standard digitalization reference architecture model is shown in Figure 1.

Standard Information Layer
The Capability Characteristics dimension corresponds to Content Digitalization. It describes the capabilities associated with the five levels of standard content: Electronic (L1), Structured (L2), Semantic (L3), Intelligent (L4), and Extendable (L5+).
The Lifecycle dimension corresponds to Process Digitalization. It describes the basic conditions that should be met for conducting digital activities across four stages: Content Creation, Content Processing, Content Delivery, and Content Application.
The Application Levels dimension corresponds to Application Digitalization. It describes the scope and objects that should be included in standard digitalization applications and services provided across five layers: Standard Information Layer, Information Interaction Layer, Related Information Layer, Scenario Service Layer, and Business Ecosystem Layer.
6 Capability Characteristics Dimension
6.1 Overview
The Capability Characteristics dimension is used to characterize the capabilities of standard content after undergoing digital processing across five levels: Electronic (L1), Structured (L2), Semantic (L3), Intelligent (L4), and Extendable (L5+). Clause 7 of GB/T 48000.1—2025 provides key activities.
