# Copyright, Licensing and Attribution Notice

## Summary

This repository mirrors 3D assets that were **created by third parties**, together with metadata
derived from them. Two different sets of rights apply, and they must not be confused.

| Part of the repository | Rights |
|---|---|
| `glb/` — the 7,373 asset files | Owned by their **original creators**. Each object keeps the licence attached to it upstream. Nothing in this repository grants you any right to them. |
| `metadata.csv`, `animations.csv`, `scripts/`, `README.md`, this notice | Produced by the repository author from public structural properties of the files. Offered under **ODC-BY 1.0**, matching the licence of the upstream Objaverse metadata. |

Publishing these files here is **not** a licence grant, a sublicence, or a claim of ownership
over any asset.

## Where the assets come from

Every file was obtained from [Objaverse and Objaverse-XL](https://objaverse.allenai.org/)
(Allen Institute for AI), which aggregates 3D objects from sources including Sketchfab and
public GitHub repositories. Objaverse-XL does not relicense what it indexes: each object remains
under whatever terms its creator applied — commonly a Creative Commons variant for Sketchfab
objects, and the licence of the containing repository for GitHub-sourced objects. Some objects
carry terms that restrict commercial use or require attribution; some carry no explicit licence
at all.

**There is therefore no single licence covering `glb/`, and none is asserted here.**

## Before you use an asset

Filenames are deliberately unchanged so that every file is traceable. The `object_id` column in
`metadata.csv` is the upstream identifier:

- `<32-hex>.glb` — an Objaverse 1.0 / Sketchfab UID
- `<24-hex>_{fbx,glb,gltf}.glb` — an Objaverse-XL object; the suffix records its original format

Resolve the licence and author for a given `object_id` through the Objaverse-XL annotations,
which carry per-object `license`, `fileIdentifier` and source fields. Determining whether your
intended use is permitted — and complying with any attribution requirement — is your
responsibility as the user of the asset, not something this repository can settle for you.

## Purpose of this mirror

The collection is published to support reproducible research on skeletal animation and motion
generation. It is a convenience copy of material that is already publicly indexed; it adds no
rights and removes none.

## Requests for removal

If you are a rights holder and an asset here should not be redistributed, it will be removed.
Open an issue or a discussion on this dataset repository identifying the `object_id` or filename
and your relationship to the work, and the file will be taken down promptly, without requiring
you to demonstrate anything further.

## Attribution

Assets: the individual creators of each object.
Aggregation and identifiers: Objaverse and Objaverse-XL, Allen Institute for AI.
Derived metadata and tooling: the repository author (see `README.md` for citation).
