The AOUSD Core Specification 1.0.1 normatively covers USD's core: data types, document data model, paths, composition, stage population, value resolution, schema extension fields and file formats. It explicitly leaves domain uses (geometry, materials, physics) to other AOUSD specifications, keeps interpolation methods out of compliance validation and reserves fields such as expressionVariables and colorManagementSystem. The supplemental sample implementations are reference quality and not normative.
