In April 2020, Graham Bell, Executive Director of EDItEUR, posted a list of the top 12 ONIX issues that cause the most problems for data recipients (PDF). In December 2021, he created a second list focused on the 12 issues faced by data senders (PDF). These lists are easy-to-use, well-explained entry points to ONIX Best Practice (which is supported by its own documentation). They’re great for the publishing supply chain to consider while they marshal their metadata resources and needs as they create and consume business information.
Both 12 ONIX issues documents are published as “Application Notes” for the ONIX 3.0 Specification, they include a full and readable explanation, and are available with other Notes on the EDItEUR website.
They were also featured in the ONIX implementation group — a mailing list that includes announcements and discussions on ONIX that you really do want to follow. Join the group.
Here are Graham’s lists, in ascending order
