History

What was tried before OIDM reached its current shape, what survives, and what superseded the rest.

• Timeline - A dated record of the Open Imaging Data Model from its anatomic-location prologue through the January 2026 status update and the 2026 work edge.
• Lineage repositories - The twelve early OIDM repositories, what each one was for, what survives into current work, and what superseded the rest.
• Extraction approaches - Seven successive attempts at turning radiology report text into structured findings, from a template corpus in 2024 to the current extraction platform, and what each one established.
• CDE template rendering - The 2023 CDETemplateDemo pattern that turned a CDE-labeled Observation into report prose through a Mustache template, and how it relates to the reporting SDK direction.
• Use case catalog - The roughly 25 use case ideas collected in the UseCases repository, organized by category, with the six value categories used to tag them.
• Site articles - The fifteen posts published on openimagingdata.org between June 2023 and March 2025, plus the About page, each dated, linked, and summarized.
