These are byte-for-byte `.json.gz` artifacts of the canonical upstream JSON-LD
publications. Each dataset carries its detailed attribution and provenance in its own
JSON-LD header; see README.md for the dataset list and refresh instructions.

The upstream `.sqlar` twins remain available for large-dataset/lazy-access use. The data
were generated with the aid of cctbx (https://cctbx.github.io/) and spglib
(https://spglib.readthedocs.io/), which carry their own separate license terms.


NOTE ON SCOPE

This file covers only the datasets in this directory. It does not apply to the httk
