# Licensing — tiny_schiller

This repository contains two separable artifacts under two different
licenses. Read this document before redistributing.

## 1. Source content — public domain

Friedrich Schiller died on **9 May 1805**. Under the EU
`Schutzdauerrichtlinie` (Directive 2006/116/EC, life + 70 years) and the
equivalent term rules in the United States (works published before 1928
are in the US public domain) and the United Kingdom, copyright in
Schiller's original works expired no later than **1 January 1876** and
has not been recoverable since.

The text content of `tiny_schiller.txt` and `tiny_schiller.parsed.txt` is
therefore in the public domain and may be freely copied, modified,
redistributed, and used for any purpose, including machine-learning
training and commercial use, with respect to **authorial** copyright.

### Edge cases

- **Critical / scholarly editions.** Modern critical editions (e.g.
  *Nationalausgabe*, recent Hanser editions) contain annotations and
  apparatus that remain in copyright. **None are used here.** The
  Projekt Gutenberg-DE digitisations use old, non-critical print
  editions whose body text is plain reprinting of public-domain works.
- **Typography and spelling.** Editorial styling, not original
  authorship; creates no new copyright.
- **EU database `sui generis` rights** (Directive 96/9/EC). We do not
  redistribute Projekt Gutenberg-DE's database structure, metadata, or
  HTML — only the underlying public-domain texts. See section 3.

## 2. Pipeline code — MIT

All scripts, configuration files, build tooling, and documentation in
this repository are licensed under the **MIT License** (see `LICENSE`).
This includes:

- everything under `scripts/`
- the `schiller_char/` and `schiller_bpe/` and `schiller_cl100k/` build
  recipes
- this file, `DATA_CARD.md`, and `README.md`

MIT does **not** apply to the textual content; the textual content is
public domain (section 1).

## 3. Source distribution terms — DraCor / GerDraCor (CC0)

This repository intentionally sources its Schiller play texts from the
DraCor API (German Drama Corpus, GerDraCor). DraCor distributes GerDraCor
under **CC0**, which is designed to be redistribution-friendly.

Accordingly:

- Upstream plain-text exports are retrieved from `https://dracor.org/api/v1/`.
- The raw concatenation lives in `tiny_schiller.txt`.
- The canonical training artifact `tiny_schiller.parsed.txt` is a
  deterministic derivative produced by `scripts/parse.py`.

Always verify upstream terms yourself if you need strict compliance
guarantees (policies can change). This repo's intent is: CC0 upstream
for the digitization layer, plus public-domain underlying works.
