IPA Publishes Supply Chain Data Collaboration Guide 2.0
Overview
IPA has published version 2.0 of the “Guide to Guidelines on Data Collaboration Mechanisms: Supply Chain Common Edition.” Referring to ODS-RAM V2, it revises the principles and functional placement diagram and clarifies how this guide should be used in individual guidelines and how it relates to the Public DPF Certification System. The aim is to apply common requirements when developing individual guidelines, thereby improving development efficiency, leveling quality across guidelines, and ensuring interoperability.
Key points
- IPA published version 2.0 of the Supply Chain Common Edition.
- The guide clarifies alignment with ODS-RAM V2 and its relationship to individual guidelines and the Public DPF Certification System.
- It sets out a policy of reusing common requirements and existing outputs when developing individual guidelines.
Overview
The importance of data sharing across companies, industries, and national borders is growing, and individual supply chain guidelines are being developed for areas such as CFP, DD, LCA, resilience, and chemical substance management. However, requirements and decisions are scattered across these guidelines, making reuse for new use cases a challenge. In March 2026, IPA published version 1.0, which organized common business, functional, and design requirements.
Assuming trust based on transaction contracts, this guide covers data collaboration between companies from raw material procurement through manufacturing and distribution.
Impact
IPA explains that developing individual guidelines based on common principles can help level quality across guidelines and ensure interoperability.
By showing how to use this guide, individual guideline authors can reuse existing outputs and develop guidelines efficiently. IPA expects these efforts to proceed on the basis of common requirements and to evolve into distributed data management across fields and national borders.
Details
This revision refers to the latest version, V2, of ODS-RAM and updates the principles, functional placement diagram, and terminology. The functional placement diagram refers to ODS-RAM’s layer structure and illustrates how to select the layers needed according to the nature of each use case.
Individual guidelines are generally expected to follow Chapter 2, “Principles,” and edit Chapter 3 onward according to the purpose and business activities of each use case. This guide presents principles, business requirements, business architecture, system architecture, and system specifications, and provides a glossary, systemized business process flows, and examples of non-functional requirements in its appendices.
Under the Public DPF Certification System, individual guidelines for the supply chain domain developed by referring to this guide may be subject to conformity checks, so the guide clarifies the relationship among this guide, individual guidelines, and the system. In addition to DX certification criteria, the system requires data collaboration system operators and managers to meet criteria such as safety and reliability, interoperability, and business stability; the Minister of Economy, Trade and Industry certifies those that do so and requires conformity with IPA guidelines and related materials.
