Authority snapshot licensing
=============================

The files in this directory are HAND-SEEDED MINIMAL SAMPLES created to prove the
P1-D authority mechanism (offline resolve → ranked authority_refs → RDF
projection). They are NOT official dumps. The labels/IRIs are illustrative and
must be replaced with real, dated exports before production use.

When real snapshots are ingested, each authority retains its own upstream terms;
record them here per authority and honour them in any redistribution:

- periodo (PeriodO)        — data released under CC0 1.0 (Public Domain).
                             https://perio.do/
- chronontology            — iDAI.chronontology / DAI; check current terms of use
                             before redistributing period definitions.
                             https://chronontology.dainst.org/
- getty (AAT/TGN/ULAN)     — Getty Vocabularies published as Linked Open Data
                             under ODC-BY 1.0 (attribution required).
                             https://www.getty.edu/research/tools/vocabularies/

The resolver attaches the per-authority `license_ref` (see provenance.json) to
every candidate it returns, so downstream consumers can honour these terms.
