Panel: Having an SBOM Is Not Enough. Introducing the OpenChain SBOM Document Quality Guide - Yoshiyuki Ito & Tsukasa Yobo, Renesas Electronics; Kiyoshi Owada, Socionext Inc.; Yumi Tomita, Cybertrust Japan Co., Ltd.; Takashi Ninjouji, Honda Motor Co., Ltd.
Wednesday October 7, 2026 14:25 - 15:05 CEST
Chamber Hall (Floor 3)
SBOM adoption is growing, driven by global regulation such as the EU Cyber Resilience Act(CRA). Today’s software supply chains are complex and global, involving many organizations, tools, and layers of dependencies. In this environment, SBOMs need to accurately share software component information without confusion.

A high‑quality SBOM enables precise, unambiguous information exchange between organizations, minimizing gaps and misinterpretation.

To achieve this, the OpenChain SBOM Working Group released a draft SBOM Document Quality Guide in April 2026 on the foundation of the Telco SBOM Guide. Global public comments have been incorporated into the official version released at this session. It defines what should be contained, how to evaluate, and how to exchange between organizations. 

In this panel, we will discuss:
- why each of us engaged in this work
- the distinct SBOM quality challenges from our own vantage points
- how we actively utilize the guide to address industry-specific quality hurdles
We hope this sparks dialogue with many addressing Cyber Resilience Act and other security regulations
