Development Metadata from Nine Public GitHub Repositories

Open-index provides development metadata for 9 public GitHub repositories, fetched via GitHub's REST and GraphQL APIs. The archive contains 10.4 million rows across 8 tables, including issues, pull requests, comments, and CI status checks. It was last updated on April 4, 2026.

Use Cases

• Modeling issue resolution time using timeline event and comment data.
• Predicting pull request merge status from code review comments and file changes.
• Analyzing developer collaboration patterns from comment and review tables.
• Studying CI/CD pipeline failures using CI status check and commit history data.

Strengths

• 10.4 million total rows provide substantial data volume.
• 8 distinct tables allow for granular analysis of different development artifacts.
• 896.3 MB of Zstd-compressed Parquet files offer efficient storage.

Limitations

• Limited to only 9 repositories, which may not be representative of all open-source projects.
• Unknown temporal coverage limits longitudinal analysis.
• Potential for API rate limit artifacts or incomplete data fetches.
