Talkie YaRN 32k Gutenberg Pre-1931 Dataset License Notes

This repository is a generated dataset assembled from multiple upstream
sources. It does not claim a new copyright over public-domain source text.

1. Text rows

The `text` fields in `train.jsonl` and `validation.jsonl` are selected from:

  common-pile/project_gutenberg_filtered
  https://huggingface.co/datasets/common-pile/project_gutenberg_filtered

The upstream dataset card describes this corpus as English Project Gutenberg
books marked as Public Domain according to the provided metadata, plus books
from PG-19. This dataset further filtered rows to records whose `rights`
metadata contains "Public Domain". The selected text is distributed here under
the public-domain status reported by the upstream source metadata.

Project Gutenberg and upstream metadata can contain mistakes or jurisdictional
differences. Users should verify source rights for their own jurisdiction and
use case.

2. Publication-year metadata

The file `metadata/gutenberg_publication_years.csv` comes from the Kaggle
dataset:

  Gutenberg Book Metadata with Publication Years
  https://www.kaggle.com/datasets/yuvalschwartz/gutenberg-book-metadata-with-publication-years

The Kaggle dataset page lists the license as "CC0: Public Domain". The metadata
CSV is therefore included here under CC0-1.0 / public-domain dedication terms.

3. Generated manifests, logs, and preparation script

The summary JSON files and reconstruction log document how this snapshot was
generated. The preparation script is included for reproducibility. It is
provided under Apache License 2.0, consistent with the associated Talkie
tooling.

4. Composite license metadata

Because the repository combines public-domain source texts, CC0 publication-year
metadata, and an Apache-2.0 preparation script, the Hugging Face card uses:

  license: other
  license_name: public-domain-gutenberg-texts-and-cc0-metadata
  license_link: LICENSE
