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).
  • Access: Registration / request form (Google Form).
  • 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) (LICENSE). The Dataset may be used for academic research, 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.
