# Attribution and licensing notice

The `studia_bas` source contains peer-reviewed articles from *Studia BAS*, the
socioeconomic and public-policy journal published by the Bureau of Research
(Biuro Analiz Sejmowych) at the Chancellery of the Sejm, taken from the
[official journal archive](https://studiabas.sejm.gov.pl/journal.nsf/pubBAS.xsp?view=12&seria=4&lang=PL).

Articles are published under the [Creative Commons Attribution 3.0
Poland](https://creativecommons.org/licenses/by/3.0/pl/) license
(`CC-BY-3.0-PL`). That license applies from issue 2(66)/2021 onward; issues
1(1) through 1(65) are marked "Wszelkie prawa zastrzeżone" and are excluded
from this source entirely. The evidence for the cutoff, together with the
SHA-256 hash of every eligible issue PDF, is recorded in
`studia_bas.license-evidence.json`.

For every released DynaWord document:

- the `author` column carries the article's author list, read from the PDF
  title page;
- `studia_bas.attribution.jsonl` preserves the article DOI, the recommended
  attribution URL, the journal archive URL, the issue number, the filename and
  SHA-256 of the issue PDF the text came from, the publisher, the license URL
  and the modification notice — one row per Parquet row, in the same order;
- the text was extracted from the text layer of the official issue PDF. Running
  headers, page numbers, author affiliation/contact blocks, and terminal
  bibliographies were removed, residual personal data was replaced with `[PII]`,
  and PDF line wrapping was normalized.

CC BY 3.0 PL requires attribution and an indication that changes were made.
When redistributing or adapting these texts, name the author and the publisher
(Kancelaria Sejmu, Biuro Analiz Sejmowych), link the license, and retain the
modification notice above.

Figures, tables, photographs and any third-party material reproduced inside the
source PDFs may carry separate rights and are not covered by this notice. Only
the extracted article text is redistributed here; the issue PDFs themselves are
not.
