--- license: cc-by-4.0 task_categories: - text-retrieval tags: - github - code - metadata - software-engineering - open-source - astronomy - machine-learning size_categories: - 1M= 3 Stars) A comprehensive metadata dataset covering **5,289,726 public GitHub repositories** with **3 or more stars (>= 3)** spanning the history of GitHub from 2008 to 2026. ## Data Recency & Snapshot Notice > [!NOTE] > - **Snapshot Methodology:** This dataset combines a comprehensive historical base archive (up to mid-2022) with continuous periodic crawler snapshots (2023 through 2026). > - **Star Counts & Metrics:** Star counts and repository metrics reflect the recorded values at the time of each repository's latest crawl/snapshot. Actively maintained projects may have higher live star counts on GitHub.com today. > - **Coverage:** Includes active and historical repositories created between 2008 and 2026. --- ## Key Features - **Total Repositories:** 5,289,726 - **Rich Topics & Descriptions:** Native tag arrays (`topics`), repo descriptions, licenses, homepage links, and star/fork metrics. - **Fast Search:** Designed for instant topical search (e.g., Astronomy, BioInformatics, WebAssembly, Robotics, Machine Learning) using DuckDB, Polars, or Hugging Face `datasets`. - **Deduplicated & Cleaned:** Deduplicated by `owner/repo`, prioritized by latest activity and rich metadata. --- ## Dataset Schema | Column | Type | Example | Description | | :--- | :--- | :--- | :--- | | `full_name` | `string` | `astropy/astropy` | Full repository name (`owner/repo`) | | `owner` | `string` | `astropy` | Organization or username | | `name` | `string` | `astropy` | Repository name | | `description`| `string` | `Astronomy and astrophysics core library for Python` | Repository description | | `topics` | `list` | `['astronomy', 'astrophysics', 'python', 'fits']` | List of repository topic tags | | `language` | `string` | `Python` | Primary programming language | | `stars` | `int64` | `4820` | Recorded stargazer count at snapshot | | `forks` | `int64` | `1540` | Recorded fork count at snapshot | | `license` | `string` | `bsd-3-clause` | Open source license key | | `homepage` | `string` | `https://www.astropy.org` | Project homepage / website | | `created_at` | `timestamp` | `2011-08-25 21:00:00` | Repository creation date | | `last_active`| `timestamp` | `2026-06-15 12:30:00` | Most recent activity / push date | --- ## Quickstart: How to Find Projects (e.g., Astronomy) ### 1. Using Hugging Face `datasets` (Streaming / No full download required) ```python from datasets import load_dataset # Stream the dataset directly from Hugging Face ds = load_dataset("Mieaz/github-repos-metadata-ge3", split="train", streaming=True) # Find all repositories with 'astronomy' or 'astrophysics' astronomy_repos = [] for repo in ds: topics = [t.lower() for t in (repo.get("topics") or [])] desc = (repo.get("description") or "").lower() if "astronomy" in topics or "astronomy" in desc or "astrophysics" in topics: astronomy_repos.append(repo) if len(astronomy_repos) >= 20: break for r in astronomy_repos: print(f"⭐ {r['stars']:>5} | {r['full_name']:<35} | {r['description'][:60]}") ``` ### 2. Using DuckDB (Instant SQL Queries on Remote Parquet) ```python import duckdb con = duckdb.connect() query = ''' SELECT full_name, stars, language, description, topics FROM 'hf://datasets/Mieaz/github-repos-metadata-ge3/data/train-*.parquet' WHERE list_contains(topics, 'astronomy') OR description ILIKE '%astronomy%' ORDER BY stars DESC LIMIT 15; ''' print(con.execute(query).df()) ``` --- ## License & Attribution - Data compiled from public open-source event logs and repository records under Creative Commons Attribution 4.0 (CC-BY 4.0).
