Version 2.0 of the Supply Chain Data Linkage Guide

The Ministry of Economy, Trade and Industry and the Digital and AI Systems Design Center (DADC) of the Information-technology Promotion Agency (IPA) prepared and published a guide that organizes common operational and functional requirements for data linkage across multiple companies in supply chains. Its purposes include protecting trade secrets, managing traceability, and realizing sustainable business architectures.

The guide aims to improve industrial competitiveness through data linkage mechanisms and to support more consistent quality and shorter development periods for industry-specific guidelines.

This document targets a wide range of industries that require distributed data management across companies, industries, and national borders, and is intended for authors of industry-specific guidelines. It references outputs of the Ouranos Ecosystem, including ODS-RAM (Open Data Spaces Reference Architecture Model), and consolidates requirements by standardizing and generalizing existing guidelines and related materials.

Appendix A is a glossary, and Appendix B contains Section 5.3, “Systemized Business Process Flow,” of Chapter 5, “System Architecture.” Appendix C provides examples of non-functional requirements referenced in Section 5.4, “Non-functional Requirements,” of the same chapter. A PowerPoint file is also available for people preparing industry-specific guidelines based on this document; those who need it can contact the listed point of contact.
