With the advancement of the digital, networked, and intelligent transformation of the economy and society, the digitalization of standards has become an inevitable trend. Various entities need to... We need to independently carry out standard digitization activities to meet the needs of standardization work in the new era and better leverage the role of standards. However, at present, there is a lack of openness... Guidance documents for exhibition-related activities, providing guidance on how to identify the main aspects and priorities of standard digitization, rationally utilize key technologies, and create a complete standard. Provide rules for accurate activity records, etc. GB/T 48000 "Standard Digitalization" is a fundamental and universal standard for carrying out standard digitalization activities in my country, aiming to improve the standard digitalization system. The system for the conceptualization, development, and application of standards should be standardized and guided to ensure the orderly progress of standardization work, promote technical exchanges, and avoid duplication of related research. The project is planned to consist of six parts.

1.General Guidelines. The aim is to provide the overall principles and basic framework for conducting standardized digitization activities, and to clarify the standards for digitization. The main aspects of chemical activities, as well as recommended practices and key technologies.

2.Reference Architecture Model. The aim is to propose a reference architecture model to describe standard digitization activities, and to support standard digitization. The system architecture and activity boundaries are clearly and visually expressed, providing reference and guidance for the planning and organization of related activities.

3.Ontology Modeling Requirements. The aim is to determine the construction methods and requirements for standard ontologies in standard digitization activities, and to provide a unified approach. A unified conceptual framework ensures the accuracy and interoperability of standard digitization.

4.Collaborative Development Requirements. The aim is to establish relevant rules for collaborative standard development in standard digitization activities, ensuring that standards... Collaborate to develop standardized procedures for carrying out the work.

5.Maturity Assessment. The aim is to provide a standardized, digitized maturity assessment system, proposing assessment indicators, procedures, and methods. Laws, etc.

6.Organization and Process Management. The aim is to provide procedures and methods for organizing and managing the processes of conducting standardized digitalization activities. Laws, etc. The reference architecture model proposed in this document comprehensively considers and fully reflects the cutting-edge progress and theoretical advancements in the digitization of standards both domestically and internationally. At the international level, IEC /SMB/SG12 proposed a standardized architecture model for digital applications in its report "SMB/7326/R". This provides a reference for quasi-digital organization and planning. At the domestic level, GB/T 48000.1 "Standards Digitization Part

1.General Guidelines" proposes... The standardization activities have three main aspects. process digitization, content digitization, and application digitization, providing a foundation for my country's standardization activities. This laid the foundation for the launch of the initiative. GB/T 48000.1 focuses on the explanation of the direction of standard digitization, and solves the questions of "what is standard digitization and what are its aspects"; This document focuses on clarifying the boundaries and connotations, and deconstructs the architecture of standard digitization through a visual model, thus solving the problem of "standard digitization". The question is, "What are the boundaries of digital activities?" Standard Digitalization Part

1 Scope

GB/T 48000.2-2026 is the Chinese national standard covering the reference architecture of standards digitalization - the layers from the content model through the knowledge base and the platform to the applications that consume standards, and how the other parts of the series fit into it. Part 2 of the series, first edition, with Parts 3 and 4. It was issued on 28 January 2026 and has been in force since 1 August 2026, as a first edition. The document is under the responsibility of the Standardization Administration of China. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document establishes the overall framework of the standard digital reference architecture model, providing aspects such as capability characteristics, lifecycle, and application layers. The guidance and suggestions were provided, along with relevant information. This document applies to individuals, organizations, institutions, and other entities.

a) Planning and organizing activities related to the digitization of standards;

b) Identify the level of digitization capability for standard content;

c) Clearly define the basic conditions for carrying out activities at each stage of the life cycle;

d) Refer to and provide standard digital application services at different levels.
