Description

OpenUSD Core Spec 1.0 is Here: Now We Need You is an Alliance for OpenUSD blog post by Aaron Luk and Nick Porcino announcing ratification of the OpenUSD Core Specification 1.0.

It frames the Core Spec as grammar and data-model rules rather than domain vocabularies, listing pillars for grammar and data types, document data model, composition, stage population and value resolution, USDA USDC and USDZ formats, and a compliance framework with sample implementations. It discusses decoupling intent from one codebase, scoping versus newer features, a planned 1.1 fast follow, and a call for working-group contributors.

It is for intermediate to advanced pipeline engineers who implement or depend on OpenUSD interchange and need normative behavior.

The article is free on aousd.org with pointers to the published spec, compliance samples, forum, and membership signup.

It is useful as the official announcement and contribution call when tracking OpenUSD Core Spec 1.0 status.
