# Ex Nihilo CODE-001: GitHub Codebase Intelligence Index (Free Sample)

A repository-level index of public GitHub projects that carry permissive open-source licenses, published by Babylon Technologies LLC. This page hosts the **free sample**. The full index and the pull-request data are sold separately (see "Full version").

## What is in the full index

- 339 repositories in Rust, Go, Java, C++, COBOL and MATLAB
- 319 in the verified cut, 205 in the premium cut [add one line saying what "verified" and "premium" mean]
- Repositories filtered by SPDX license identifier: MIT, Apache-2.0, BSD-2-Clause, BSD-3-Clause
- Harvest frozen on 2026-09-16, so results are reproducible
- Estimated lines of code per repository, built from GitHub linguist language bytes divided by a language-specific bytes-per-line calibration (not a fixed multiple of repository size)

## What is in this sample

- 100 rows, sorted by star count. A star-sorted sample is not a random sample, so it over-represents popular projects. Do not use it to estimate statistics about GitHub as a whole.
- Columns include: repo_id, repo_name, owner, language, stars, forks, contributor count [add the remaining columns from your data dictionary, with one-line definitions]
- These columns are repository metadata. [Confirm: no source code is included in this sample.]
- Data dictionary excerpt: [link or file name]

## Full version (paid)

Everything above, plus:
- Full, verified and premium CSV files
- Complete documentation and summary statistics
- A frozen harvest of 1,020 public pull-request file lists and patches

## Intended uses

- Benchmarking and sampling for code-related machine learning research
- Comparing repository activity (stars, forks, contributors) across languages
- Choosing candidate repositories for further study

## Limitations

- A snapshot taken on 2026-09-16. Repositories change after that date.
- Lines-of-code figures are estimates, and the method above has known error.
- Coverage is limited to the six languages and four licenses listed.
- A permissive license on a repository does not remove obligations such as attribution. Users of any code or patches in the paid version are responsible for complying with each repository's license.
