+# OpenGitHub Meta
+
+## What is it?
+
+The full development metadata of 1 public GitHub repository, fetched from the [GitHub REST API](https://docs.github.com/en/rest) and [GraphQL API](https://docs.github.com/en/graphql), converted to Parquet and hosted here for easy access.
+
+Right now the archive has **5.1K rows** across 8 tables in **956.7 KB** of Zstd-compressed Parquet. Every issue, pull request, comment, code review, timeline event, file change, and CI status check is stored as a separate table you can load individually or query together.
+
+This is the companion to [OpenGitHub](https://huggingface.co/datasets/open-index/open-github), which mirrors the real-time GitHub event stream via [GH Archive](https://www.gharchive.org/). That dataset tells you what happened across all of GitHub. This one gives you the full picture for specific repos: complete issue threads, full PR review conversations, the state machine from open to close.
+
+People use it for:
+
+- **Code review research** with inline comments attached to specific diff lines
+- **Project health metrics** like merge rates, review turnaround, label usage
+- **Issue triage and classification** with full text, labels, and timeline
+- **Software engineering process mining** from timeline event sequences
+
+Last updated: **2026-03-28**.

+## Repositories
+
+| Repository | Issues | PRs | Comments | Reviews | Timeline | Total |
+|---|---:|---:|---:|---:|---:|---:|
+| **facebook/react** | 999 | 0 | 0 | 0 | 4.1K | 5.1K |
+
+## How to download and use this dataset
+
+Data lives at `data/{table}/{owner}/{repo}/0.parquet`. Load a single table, a single repo, or everything at once. Standard Hugging Face Parquet layout, works with DuckDB, `datasets`, `pandas`, and `huggingface_hub` out of the box.
+
+### Using DuckDB
+
+DuckDB reads Parquet directly from Hugging Face, no download step needed. Save any query below as a `.sql` file and run it with `duckdb < query.sql`.
+
+```sql
+-- Top issue authors across all repos
+SELECT
+    author,
+    COUNT(*) as issue_count,
+    COUNT(*) FILTER (WHERE state = 'open') as open,
+    COUNT(*) FILTER (WHERE state = 'closed') as closed
+FROM read_parquet('hf://datasets/open-index/open-github-meta/data/issues/**/0.parquet')
+WHERE is_pull_request = false
+GROUP BY author
+ORDER BY issue_count DESC
+LIMIT 20;
+```
+
+```sql
+-- PR merge rate by repo
+SELECT
+    split_part(filename, '/', 8) || '/' || split_part(filename, '/', 9) as repo,
+    COUNT(*) as total_prs,
+    COUNT(*) FILTER (WHERE merged) as merged,
+    ROUND(COUNT(*) FILTER (WHERE merged) * 100.0 / COUNT(*), 1) as merge_pct
+FROM read_parquet('hf://datasets/open-index/open-github-meta/data/pull_requests/**/0.parquet', filename=true)
+GROUP BY repo
+ORDER BY total_prs DESC;
+```
+
+```sql
+-- Most reviewed PRs by number of review submissions
+SELECT
+    r.pr_number,
+    COUNT(*) as review_count,
+    COUNT(*) FILTER (WHERE r.state = 'APPROVED') as approvals,
+    COUNT(*) FILTER (WHERE r.state = 'CHANGES_REQUESTED') as changes_requested
+FROM read_parquet('hf://datasets/open-index/open-github-meta/data/reviews/**/0.parquet') r
+GROUP BY r.pr_number
+ORDER BY review_count DESC
+LIMIT 20;
+```
+
+```sql
+-- Label activity over time (monthly)
+SELECT
+    date_trunc('month', created_at) as month,
+    COUNT(*) as label_events
+FROM read_parquet('hf://datasets/open-index/open-github-meta/data/timeline_events/**/0.parquet')
+WHERE event_type = 'LabeledEvent'
+GROUP BY month
+ORDER BY month;
+```
+
+```sql
+-- Largest PRs by lines changed
+SELECT
+    number,
+    additions,
+    deletions,
+    changed_files,
+    additions + deletions as total_lines
+FROM read_parquet('hf://datasets/open-index/open-github-meta/data/pull_requests/**/0.parquet')
+ORDER BY total_lines DESC
+LIMIT 20;
+```
+
+### Using Python (`uv run`)
+
+These scripts use [PEP 723](https://peps.python.org/pep-0723/) inline metadata. Save as a `.py` file and run with `uv run script.py`. No virtualenv or `pip install` needed.
+
+**Stream issues:**
+
+```python
+# /// script
+# requires-python = ">=3.11"
+# dependencies = ["datasets"]
+# ///
+from datasets import load_dataset
+
+ds = load_dataset("open-index/open-github-meta", "issues", streaming=True)
+for i, row in enumerate(ds["train"]):
+    print(f"#{row['number']}: [{row['state']}] {row['title']} (by {row['author']})")
+    if i >= 19:
+        break
+```
+
+**Load a specific repo:**
+
+```python
+# /// script
+# requires-python = ">=3.11"
+# dependencies = ["datasets"]
+# ///
+from datasets import load_dataset
+
+ds = load_dataset(
+    "open-index/open-github-meta",
+    "pull_requests",
+    data_files="data/pull_requests/facebook/react/0.parquet",
+)
+df = ds["train"].to_pandas()
+print(f"Loaded {len(df)} pull requests")
+print(f"Merged: {df['merged'].sum()} ({df['merged'].mean()*100:.1f}%)")
+print(f"\nTop 10 by lines changed:")
+df["total_lines"] = df["additions"] + df["deletions"]
+print(df.nlargest(10, "total_lines")[["number", "additions", "deletions", "total_lines"]].to_string(index=False))
+```
+
+**Download files:**
+
+```python
+# /// script
+# requires-python = ">=3.11"
+# dependencies = ["huggingface-hub"]
+# ///
+from huggingface_hub import snapshot_download
+
+# Download only issues
+snapshot_download(
+    "open-index/open-github-meta",
+    repo_type="dataset",
+    local_dir="./open-github-meta/",
+    allow_patterns="data/issues/**/*.parquet",
+)
+print("Downloaded issues parquet files to ./open-github-meta/")
+```
+
+For faster downloads, install `pip install huggingface_hub[hf_transfer]` and set `HF_HUB_ENABLE_HF_TRANSFER=1`.

+
+## How it's built
+
+The sync pipeline uses both GitHub APIs. The [REST API](https://docs.github.com/en/rest) handles bulk listing: issues, comments, and review comments are fetched repo-wide with `since`-based incremental pagination and parallel page fetching across multiple tokens. The [GraphQL API](https://docs.github.com/en/graphql) handles per-item detail: one query grabs reviews, timeline events, file changes, and commit statuses in a single round trip, with automatic REST fallback for PRs with more than 100 files or reviews.
+
+Multiple GitHub Personal Access Tokens rotate round-robin to spread rate limit load. The pipeline is fully incremental and idempotent: re-running picks up only what changed since the last sync.
+
+Everything lands in per-repo [DuckDB](https://duckdb.org/) files first, then gets exported to Parquet with Zstd compression for publishing here. No filtering, deduplication, or content changes. Bot activity, automated PRs, CI noise, Dependabot upgrades, all of it is preserved, because that's how repos actually work.
+
+## Known limitations
+
+- **Point-in-time snapshot.** Data reflects the state at the last sync, not real-time. Incremental updates capture everything that changed since the previous sync.
+- **Bot activity included.** Comments and PRs from bots (Dependabot, Renovate, GitHub Actions, etc.) are included without filtering. This is intentional. Filter on `author` if you want humans only.
+- **JSON columns.** `labels`, `assignees`, `reactions`, and `data` contain JSON strings. Use `json_extract()` in DuckDB or `json.loads()` in Python.
+- **Body text can be large.** Issue and comment bodies contain full Markdown, sometimes with embedded images. Project only the columns you need for memory-constrained workloads.
+- **Timeline data varies by event type.** The `data` field in `timeline_events` contains the raw event payload as JSON. The schema depends on `event_type`.
+
+## Personal and sensitive information
+
+Usernames, user IDs, and author associations are included as they appear in the GitHub API. All data was already publicly accessible on GitHub. Email addresses do not appear in this dataset (they exist only in git commit objects, which are in the separate code archive, not here). No private repository data is present.
