Per-file evidence / 16 October 2026

Rights, files & boundaries.

Model preview images are rendered from the same inspected geometry and supplied textures. Their source asset licenses, credits and share-alike obligations listed below also apply to these derived previews; no outside catalog photographs are used.

Commercial adaptation and redistribution are recorded per asset. CC BY requires credit, source, license and changes. The Cliff Palace adaptation remains CC BY-SA 4.0. CC0 provenance is retained. NASA educational/factual-use guidelines have endorsement, third-party and promotional restrictions; no blanket public-domain claim is made. Copied original records retain their existing obligations.

Carnegie Mansion · Main Floor

Carnegie Mansion scan by 3D Systems, courtesy of Cooper Hewitt, Smithsonian Design Museum. CC0 1.0. Geometry and supplied color textures covered by the museum’s model-specific release.

359 web meshes; 84,057 triangles; 101 embedded image textures. Source chunks/materials are not assumed to be physical components. No exploded view is offered.

Adaptation: Geometry and materials reserialized; embedded textures reduced to at most 256 pixels per dimension. Original floor package retained privately and kept separate from the exterior.

Cliff Palace, Mesa Verde

John Toeppen. Cliff Palace, Mesa Verde. https://sketchfab.com/3d-models/cliff-palace-mesa-verde-colorado-4ad7f4618b3244b8862f68c104e2ba84. CC Attribution-ShareAlike 4.0. Geometry and embedded supplied textures from the same downloaded package; no outside photographs imported. The adapted GLB is distributed under CC BY-SA 4.0; attribution, source link, modification notice and this same license travel with the model. The website as a whole is not relicensed.

39,897 web triangles; 1 supplied geometry groups before runtime flattening. Generic mesh chunks are not physical components. Thirty-nine oversized source closing/filler faces removed. Open edges, capture artifacts and incomplete surfaces remain; this is not a complete measured building. Source carries a NoAI platform tag; retained in provenance. No generative model creation or training was used in this adaptation. Independent creator: John Toeppen; the item links National Park Service historical context.

Adaptation: Texture cap 512px (JPEG 85 for opaque images, PNG for transparency); duplicate/unused data removed; welded vertices; Draco encoding; supplied mesh-bearing nodes retained. Removed 39 oversized closing/filler faces (edge >20% of source extent and area >0.25% of extent squared) to expose the recorded scan surface; not a reconstruction of missing architecture.

Other research holds and exclusions

These eighteen alternatives were separate from the 54-entry implementation shortlist. Two are now promoted as additional studies; sixteen remain excluded or held for the reasons below.

Parthenon

Already introduced on Everything Museum. No new Parthenon entry recommended.

Recorded source

Anta Grande do Zambujeiro — Global Digital Heritage version

CC BY-NC; not eligible for general commercial reuse. A different Morbase CC0 scan is included above.

Recorded source

The Royal Tombs — Petra, Jordan

Excellent institutional collaboration, but item license is CC BY-NC. Hold unless the project is strictly eligible for NC terms or gets a separate license.

Recorded source

Temple de Chichen Itza — sowillo

CC BY-NC-ND. Noncommercial and NoDerivatives terms make a commercially reusable, optimized mesh workflow unsuitable without separate permission.

Recorded source

Great Pyramid of Giza — saVRee

View/embed page has no download offer or open model license. Do not extract the viewer model.

Recorded source

The Great Pyramid of Giza — ianicolo

CC BY label, but description says it was reconstructed from YouTube videos without identifying source-footage reuse rights. Hold for provenance clarification.

Recorded source

York Minster — Chris Bibb

CC BY label, but capture source is unnamed YouTube video frames. Hold for source-footage provenance.

Recorded source

White House — Microsoft STL

Promoted after actual STL geometry inspection: 2,960 triangles, no textures. Published as an approximate Microsoft miniature with unverified proportions explicitly disclosed; not a measured architectural reconstruction.

Recorded source

Cabin from Point of Pines Plantation

Promoted after exact format and media-level CC0 verification. The listed Smithsonian GLB was downloaded, inspected and published as the Point of Pines cabin study.

Recorded source

Devonaboy Jome Masjidi

Rechecked the creator’s current item README and attribution file. The CC BY-SA model includes 149 supplied textures derived from photographs. The author explicitly flags the 2019–2021 architectural reconstruction as a new work and states that the model license cannot grant rights to that design. Commercial architectural-design clearance remains unresolved; no model was imported.

Recorded source

Smithsonian Tyrannosaurus and Triceratops / Tyrannosaurus rex

The item-specific 3D media notice restricts reuse to noncommercial educational/personal purposes despite offered downloads. Exclude from a commercially reusable shortlist. This is not the unrestricted Hatcher model already in the museum.

Recorded source

Colossal marble bust of Zeus — British Museum

Item is CC BY-NC-SA, not commercially reusable.

Recorded source

Scotch Boiler from PS Waverley — Scottish Maritime Museum

Item is CC BY-NC. Other models from this museum are CC0, but this one is not.

Recorded source

Venus III of Willendorf — Natural History Museum Vienna

OBJ/MTL/PNG offered, but the item is CC BY-NC 4.0. A free download does not confer commercial reuse.

Recorded source

Vaca Muerta mesosiderite — Delft Meteorite Lab

No downloadable model or open item license verified; viewer availability is insufficient.

Recorded source

Hatcher Triceratops mounted skeleton

Already present in the supplied codex; exclude as duplicate rather than a rights problem.

Recorded source

BodyParts3D: additional human anatomy meshes

Human anatomy is already extensively represented, so this is a future source/rights refresh rather than a new subject. The official license page changed to CC BY 4.0 on 2025-02-27; older archives and existing paid derivatives may retain different terms. Do not relabel the museum’s current Kabe-Tech/always3d derivatives based on the current source-site license.

Recorded source

Buckingham Palace and Royal Household virtual tours

A public panorama or virtual tour is viewable content, not an item-level downloadable/open 3D model grant. The existing credits already reference a palace viewing resource; do not extract viewer assets or count that as a new reusable model.
