# Open Scientific Code Registry (OSCR): the authors' scripts

The code published by the authors of open-access neuroscience papers, as found and
verified by Open Scientific Code Registry (OSCR). Each file is here exactly as it is at the source, at the verified
commit, **under the license of its repository**.

- **136,878 unique files** (1,165 MB of text) from **2,737 repositories**,
  in 8 Parquet block(s).
- **Only files whose repository's license allows redistribution**, confirmed by the
  repository's own license file (or, for an archive without one, by its record). Files
  without such a license are never copied here: Open Scientific Code Registry (OSCR) links to them at the source.
- No text of any paper.

## Layout

- `blocks/NNNNN.parquet`: one row per unique file (SHA-256 of its text):
  `sha256`, `language`, `size`, `lines`, `content`. zstd page compression, 64 rows per
  row group: a single file can be read with HTTP range requests (for example with
  hyparquet in a browser). A published block never changes; new files go into new
  blocks.
- `manifests/<xx>/<repository>.json`: per repository, its URL, commit and license, and
  for each file its path, digest, and the (block, row) holding its text.

## Licenses

Each file keeps the license of its repository, given in the repository's manifest
(`license`, `license_confirmed_by`). Repositories by license:
