Score: 43/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 23, release rhythm 35, longevity 100
- inputs: {"age_days": 5289, "days_push": 465, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
GH Archive records the public GitHub timeline into hourly JSON event archives and makes them freely downloadable, plus available as a public BigQuery dataset. This repository hosts the project's website and tooling, not the dataset itself.

## Use cases
- download historical github event data for analysis
- query github activity with bigquery
- research open source developer behavior
- build visualizations from github timeline data
- mine github events for trends
- analyze pull request and issue activity over time

## When to choose
- you need bulk historical GitHub event data for research or analytics
- you want SQL access to GitHub activity via BigQuery
- you're building visualizations or studies of open source ecosystems

## When to avoid
- you need real-time GitHub event streaming rather than hourly archives
- you want private repository data
- you need a ready-made analysis tool rather than raw data

## Facets
- artifact type: dataset
- maturity: active
- function: data-science, analytics, etl, json
- domain: data-science, big-data, analytics, developer-tools, version-control
- platform: cloud, python, ruby
- tags: github-archive, public-dataset, bigquery, event-data, open-data, research, web-server
