## Python dependencies

Installed from PyPI at build time, not bundled: see `requirements.txt` and `requirements-dev.txt`. Checked 2026-10-17 from the installed package metadata: MIT, BSD-2/3-Clause, Apache-2.0, MPL-2.0 (certifi), PSF-2.0, MIT-CMU (pillow) and ZPL-2.1 (zope.event, zope.interface). All are permissive or weak-copyleft open-source licences that fit MIT; none is source-available only.

## Catalogue data and images

Brick Work bundles no catalogue data or images from BrickLink or Brickset, and no pictures from any of them (the demo's illustrations are original drawings, see above). The mapping files in `brickwork/catalogue/mappings/` are derived from data of [Rebrickable](https://rebrickable.com) (its downloadable dump and the external ids of its API); Rebrickable allows free use with acknowledgement, which this entry gives. They map Rebrickable's colours, parts and themes to BrickLink and LEGO identifiers and carry no BrickLink catalogue data. Each install loads its own BrickLink and Rebrickable catalogue files and uses its own API keys; pictures are fetched by the install and stored locally.

## Trademarks

LEGO® is a trademark of the LEGO Group of companies, which does not sponsor, authorize or endorse this project. Rebrickable and Brickset are trademarks of their owners.

The term 'BrickLink' is a trademark of the LEGO Group BrickLink. This application uses the BrickLink API but is not endorsed or certified by LEGO BrickLink, Inc. (BrickLink API terms; the same notice is in the app under Tools & Admin → About.)
