| # Provenance and licensing notes |
|
|
| This document supports maintainers choosing between a **public** and **gated** Hugging Face dataset release. |
|
|
| ## What this repository contains |
|
|
| - **Derived artifacts only:** SuperFit primitive assemblies, fit configs, and evaluation summaries, stored under `dataset/toys4k/` and `dataset/partobjaverse/`. |
| - **No Toys4K `.obj` / blend meshes** and **no PartObjaverse `.glb` meshes** are included. |
| - Instance IDs align with the public benchmarks so users can join against meshes they obtain separately. |
|
|
| ## Source datasets |
|
|
| ### Toys4K |
|
|
| - **Paper:** Stojanov, Thai, Rehg — CVPR 2021 ([project page](https://rehg-lab.github.io/publication-pages/lowshot-shapebias/)). |
| - **Access:** Registration / request form ([Google Form](https://forms.gle/w7Zf82umwaKxr9L7A)). |
| - **Implication for Hub:** Because Toys4K requires explicit approval, a **gated** Hugging Face dataset that asks users to acknowledge Toys4K terms is prudent even though this repo does not ship Toys4K files. |
|
|
| ### PartObjaverse / Objaverse |
|
|
| - **Objaverse** metadata and objects use mixed licenses (ODC-By for the corpus; per-asset CC variants including **CC-BY-NC**). |
| - **PartObjaverse-Tiny** (200-object eval set used here) is a curated subset with part annotations; confirm IEEE DataPort / paper terms before open redistribution. |
| - **Implication for Hub:** Derived fits keyed by Objaverse UIDs should inherit **per-object license constraints**. Users must verify NC or SA restrictions before commercial use. |
|
|
| ## Recommended release posture |
|
|
| | Posture | When to use | |
| |---------|-------------| |
| | **Gated** (recommended default) | Toys4K access not verified for all downloaders; mixed Objaverse per-object licenses; non-commercial CC BY-NC 4.0 restriction must be acknowledged | |
| | **Public** | After legal review confirms derived-assembly redistribution under CC BY-NC 4.0 is allowed and README clearly states source-dataset obligations | |
|
|
| ## This release's license |
|
|
| The assemblies and documentation in this repository are released under |
| **Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)** |

| teaching, and other non-commercial scholarly purposes only**. Commercial use |
| requires prior written permission from the authors. |
|
|
| This license applies to our **derived artifacts** (fits, configs, manifests, |
| documentation) and not to any third-party source meshes. Downstream use must |
| still independently comply with Toys4K and Objaverse / PartObjaverse terms |
| for the original 3D assets. |

|
| ## Maintainer checklist before `git push` |
|
|
| 1. Run `python scripts/sanitize_configs.py` (null `AOT_ARTIFACT_FILE`). |
| 2. Run `python scripts/build_manifest.py`. |
| 3. Run `python scripts/validate_release.py`. |
| 4. Confirm `git lfs track "*.pkl"` / `.gitattributes` before committing binaries. |
| 5. Set Hugging Face dataset visibility (gated vs public) and acceptance text referencing this file. |
