Description#

This feature defines the Standard OpenUSD semantic-label contract for assets that need ground-truth object identity for perception, synthetic data generation, or sensor validation workflows. An asset that satisfies this feature has semantic labels authored with the modern SemanticsLabelsAPI schema. The contract is taxonomy-agnostic: any SemanticsLabelsAPI instance name may be used.

Static validation verifies that render/default geometry is semantically labeled, that labels use the modern SemanticsLabelsAPI schema, and that any deprecated SemanticsAPI labels have been migrated. Labels may be authored directly on a renderable geometric prim, inherited from an ancestor, or provided through a bound material.

OpenUSD permits time-varying labels, so this neutral feature allows them. NVIDIA-specific rules are separate features: static labels and material labels belong to FET_011_RTX, and Wikidata Q-code formatting to FET_046_STANDARD.

Dependency Graph#

This feature has no dependencies. Taxonomy features such as FET_040_STANDARD–FET_045_STANDARD and FET_046_STANDARD may depend on it.

Use Cases#

Products or workflows that consume this feature:

  • NDAS SDG / Stargate

  • MEGA

  • Lightwheel SOW1

  • Isaac Sim semantic-label runtime checks

  • Synthetic data generation and ML ground-truth workflows

Requirement List#

Pipelines#

Source file type:

  • .usd, .usda, .usdc

    • Author semantic labels with SemanticsLabelsAPI:<instance> and semantics:labels:<instance>.

  • .blend

    • Via Blender SimReady Add-ons.

  • .mjcf

    • Via Blender SimReady Add-ons and MJCF2USD tooling.

  • .step

    • Via Blender SimReady Add-ons and CAD Converter tooling.

Validation or runtime pipeline:

  • SimReady validation - verifies the SL.001, SL.002, and SL.003 semantic-label contract.

  • Semantic Labels Check - renders semantic-label validation evidence and highlights missing labels.
