# Dataset Card for OpenGameArt-Mixed-Licenses

### Dataset Summary
This dataset contains game artwork assets collected from [OpenGameArt.org](https://opengameart.org) that are available under multiple licenses simultaneously. This dataset includes assets where creators have made their work available under two or more license options. The dataset includes various types of game assets such as 2D art, 3D art, concept art, music, sound effects, textures, and documents along with their associated metadata, all offering flexible licensing terms for different usage scenarios.

### Languages
The dataset is primarily monolingual:
- English (en): All asset descriptions and metadata are in English

## Dataset Structure

### Data Files
The dataset consists of:
- Asset files organized by type (stored across multiple ZIP archives)
- Corresponding metadata in compressed JSONL format (*.jsonl.zst) using Zstandard compression, categorized by asset type:
  - 2D_Art.jsonl.zst
  - 3D_Art.jsonl.zst
  - Concept_Art.jsonl.zst
  - Document.jsonl.zst
  - Music.jsonl.zst
  - Sound_Effect.jsonl.zst
  - Texture.jsonl.zst
- An archive_index.csv file mapping asset filenames to their respective archive files

### Data Fields
- `url`: URL to the asset page on OpenGameArt.org
- `title`: Title of the artwork/asset
- `author`: Creator of the asset
- `author_url`: URL to the creator's profile page
- `post_date`: Date when the asset was posted
- `art_type`: Type of asset (2D Art, 3D Art, Concept Art, Document, Music, Sound Effect, Texture)
- `tags`: Array of tags associated with the asset
- `licenses`: Array of licenses applicable to the asset (each entry contains multiple license options)
- `collections`: Array of collections the asset belongs to
- `preview_images`: Array of URLs to preview images of the asset
- `description`: Description of the asset provided by the creator
- `files`: Array of file information, each containing:
  - `url`: URL to download the file
  - `name`: Filename
  - `size`: File size

### Data Splits
The dataset is organized into separate splits by asset type:
| Split | Description | Number of Examples |
|-------|-------------|-------------------|
| `2d_art` | 2D game artwork and sprites | 2,087 |
| `3d_art` | 3D models and assets | 498 |
| `concept_art` | Concept artwork and designs | 93 |
| `document` | Text-based game assets like names, stories | 2 |
| `music` | Game music and background tracks | 929 |
| `sound_effect` | Sound effects for games | 165 |
| `texture` | Textures for game development | 351 |

Total dataset size: 4,125 entries

# License Information

## Multi-Licensing Structure

Each work in this dataset is available under multiple licenses simultaneously. This multi-licensing approach provides users with flexibility, allowing you to choose the license that best aligns with your project's requirements.

### Choosing a License for an Asset

Since assets often list multiple available licenses in their metadata, you need to select which one applies to your use case:

*   **For Use:** You **must select and comply with only one** of the licenses explicitly offered by the creator for that specific asset. You are **not** required to comply with all listed licenses simultaneously.
*   **For Redistribution/Editing:** While you only need to follow one license for your use, it is **strongly encouraged** to include or maintain all the original license options when you redistribute or share modified versions. This ensures the asset remains usable by the widest possible range of future projects and respects the creator's original intent.

## How to Use Assets from this Dataset

1.  **Check Available Licenses:** For any specific asset you wish to use, consult the `"licenses"` field in its associated metadata file to identify the licenses the creator has made it available under.
2.  **Select a License:** Choose **one license** from the available options listed in the metadata. You can only use licenses explicitly offered by the creator for that asset.
3.  **Comply with Requirements:** Adhere strictly to all terms and conditions of the single license you have selected.

## Summary of Common License Requirements

*   **Attribution (Required for CC-BY, CC-BY-SA, OGA-BY, GPL):** You must give appropriate credit to the creator.
*   **Share-Alike (Required for CC-BY-SA, GPL):** If you create derivative works, you must distribute them under the same or a compatible license.
*   **No Legal Requirement for Attribution (CC0):** While not legally required, attribution is still greatly appreciated by creators.
