Open Food Facts Database
What is 🍊 Open Food Facts?
A food products database
Open Food Facts is a database of food products with ingredients, allergens, nutrition facts and all the tidbits of information we can find on product labels.
Made by everyone
Open Food Facts is a non-profit association of volunteers. 25.000+ contributors like you have added 1.7 million + products from 150 countries using our Android or iPhone app or their… See the full description on the dataset page: https://huggingface.co/datasets/openfoodfacts/product-database.VSRQA_DatabaseFolder Description:
GT -- original Full HD uncompressed videos. Folder corresponding to each video contains all frames of this video
GTCompressed -- videos from "GT" folder with reduced resolution and compressed with different video codecs ("No SR Track"). Folder corresponding to each of the video contains all frames of this compressed video. Folders are named in the following format: "<sequence name>___<scale factor>_<codec name>_<values of target bitrate or qp>"

Aix-compatible Lichess database
This dataset contains the Lichess database of 7+ billion chess games, but in a format queryable using Aix, with the aixchess extension for DuckDB.
Three compression levels (Low, Medium, and High) are offered for the chess game encoding, enabling a trade-off between decoding speed and size. The Parquet files themselves are all zstd-compressed at level 19.
Generated using pgn-to-aix.
See my blog post for more details.

HAKARI-Bench Leaderboard Database
This dataset hosts the DuckDB database used by the
HAKARI-Bench leaderboard.
It is derived from the raw benchmark result artifacts in
hakari-bench/results
and is packaged for leaderboard, viewer, notebook, and SQL use.
The database is produced by the HAKARI-Bench implementation in
hakari-bench/hakari-bench.
Because the benchmark code, schema, and build workflow evolve over time, this
dataset card intentionally points to the canonical… See the full description on the dataset page: https://huggingface.co/datasets/hakari-bench/leaderboard_database.ord-data

Getting the Data
The datasets live under data/ and are stored with
Git LFS. LFS reads are redirected to the
Hugging Face mirror
via .lfsconfig, so dataset objects are fetched from Hugging
Face's CDN rather than from GitHub's shared (and limited) LFS bandwidth. This is
automatic — you do not need to configure anything.
Option 1: Clone the repository
git clone https://github.com/open-reaction-database/ord-data.git
With Git LFS installed… See the full description on the dataset page: https://huggingface.co/datasets/open-reaction-database/ord-data.trip-plus-databasef2d-database-v2

Synthetic Iris Image Dataset
Overview
This repository contains a dataset of synthetic colored iris images generated using diffusion models based on our paper "Synthetic Iris Image Generation Using Diffusion Networks." The dataset comprises 17,695 high-quality synthetic iris images designed to be biometrically unique from the training data while maintaining realistic iris pigmentation distributions. In this repository we contain about 10000 filtered iris images with the… See the full description on the dataset page: https://huggingface.co/datasets/fatdove/Iris_Database.HITECH_DATABASEfukinoto-databaseh-rag_databasellmops-database

Dataset Card for Chinese Traditional Instrument Sound
Original Content
The original dataset is created by [1], with no evaluation provided. The original CTIS dataset contains recordings from 287 varieties of Chinese traditional instruments, reformed Chinese musical instruments, and instruments from ethnic minority groups. Notably, some of these instruments are rarely encountered by the majority of the Chinese populace. The dataset was later utilized by [2] for Chinese… See the full description on the dataset page: https://huggingface.co/datasets/ccmusic-database/CTIS.spider-databases
Spider Databases (SQLite)
A re-host of the SQLite databases from the Spider
text-to-SQL benchmark (Yu et al., 2018), packaged as spider_data.zip so it can be pinned by
commit SHA and verified by checksum.
The standard xlangai/spider parquet ships only the question/SQL pairs — not the databases
needed to execute queries. This repo fills that gap for reproducible execution-based evaluation.
Contents: spider_data/database/<db_id>/<db_id>.sqlite, spider_data/tables.json, and the… See the full description on the dataset page: https://huggingface.co/datasets/HAL-9001/spider-databases.steam-databasecy-database
