# OpenUSD **Aliases:** OpenUSD Core Specification 1.0 **Entity class:** World substrate **Integration priority:** P1 **Collections:** [[collections/Consciousness Continuity|Consciousness Continuity]] · [[collections/Neurotech|Neurotech]] · [[collections/Machine Succession|Machine Succession]] **Canonical source article:** [[articles/Mind Uploading and AI — The Host is Reusable and the Person is the Delta|Mind Uploading and AI — The Host is Reusable and the Person is the Delta]] ## Definition **OpenUSD** — Pixar-originated interoperable scene framework now used for digital twins/robotics. This entry treats the technology or concept as a concrete part, precedent, or comparison within host-infrastructure analysis; it does not by itself establish consciousness transfer, personal continuity, or a company's intent to build either. <!-- BEGIN HOST RESIDUAL RELATIONSHIP GRAPH 2026-09-10 --> ## Relationships ### Host–residual infrastructure patch — 2026-09-10 **Resolved aliases:** `OpenUSD Core Specification 1.0` **Collections:** [[collections/Consciousness Continuity|Consciousness Continuity]] · [[collections/Neurotech|Neurotech]] · [[collections/Machine Succession|Machine Succession]] **Canonical source article:** [[articles/Mind Uploading and AI — The Host is Reusable and the Person is the Delta|Mind Uploading and AI — The Host is Reusable and the Person is the Delta]] **Related acquisition source:** [[articles/Technologies for Consciousness Mapping and Transfer|Technologies for Consciousness Mapping and Transfer]] **Relationship source:** [[research/Mind Uploading and AI Host-Residual Ecosystem Relationship Graph - 2026-09-10|Mind Uploading and AI Host-Residual Ecosystem Relationship Graph — 2026-09-10]] #### Host-infrastructure integration Pixar-originated interoperable scene framework now used for digital twins/robotics. #### Outgoing typed edges - **HR-0253 — `used_by` → `NVIDIA Omniverse`** — **VERIFIED EXTERNAL**; evidence `ARTICLE`, `WEB_NEWTON`. Shared scene representation. - **HR-0262 — `technical_convergence_with` → [[wiki/Digital Twin Interoperability|Digital Twin Interoperability]]** — **STRONG ANALYTIC CONVERGENCE**; evidence `WEB_NEWTON`, `WIKI_ARCHIVE`. Shared scene ontology/reference semantics enable exchange across tools. - **HR-1412 — `cross_threads` → [[wiki/reference-plus-delta architecture|Reference-Plus-Delta Architecture]]** — **HIGH VALUE CROSS THREAD**; evidence `ARTICLE`, `WIKI_ARCHIVE`. Instancing stores one canonical scene asset plus per-instance transforms/overrides. - **HR-1413 — `cross_threads` → [[wiki/World Modeling|World Modeling]]** — **HIGH VALUE CROSS THREAD**; evidence `ARTICLE`, `WIKI_ARCHIVE`. Scene graphs provide persistent addressable world structure beneath generative elaboration. - **HR-1567 — `ratified_by` → `multi-company AOUSD membership`** — **VERIFIED EXTERNAL**; evidence `WEB_AOUSD_CORE`. Canonical basis for independent implementations. - **HR-1568 — `cross_threads` → [[wiki/Standards as Governance|Standards as Governance]]** — **ANALYTIC CONVERGENCE**; evidence `WEB_AOUSD_CORE`, `WIKI_ARCHIVE`. Shared world representation becomes governed interoperability substrate. #### Incoming typed edges - **HR-0252 — [[wiki/Universal Scene Description|Universal Scene Description]] `publicly_released_as` → this entry** — **VERIFIED EXTERNAL**; evidence `ARTICLE`. Open-source scene description lineage. - **HR-0255 — [[wiki/Newton Physics Engine|Newton Physics Engine]] `built_on` → this entry** — **VERIFIED EXTERNAL**; evidence `WEB_NEWTON`, `WEB_NEWTON_GTC`. Official. - **HR-1566 — [[wiki/Alliance for OpenUSD|Alliance for OpenUSD]] `standardizes` → this entry** — **VERIFIED EXTERNAL**; evidence `WEB_AOUSD`, `WEB_AOUSD_CORE`. Normative interoperability. #### Epistemic boundary Evidence status and relationship type are recorded on each typed edge; graph candidates remain labeled **CANDIDATE — DO NOT PROMOTE**. <!-- END HOST RESIDUAL RELATIONSHIP GRAPH 2026-09-10 -->
