Contributions accepted into the corpus are licensed to OnCo on the same terms
so that the whole corpus can be offered under one licence.

The corpus describes third-party products, organisations, trials and publications.
Facts are not copyrightable; the licence covers OnCo's selection, arrangement,
wording and derived files. Trademarks belong to their owners. Linked external
sources and anything ingested from upstream keep their own licences, recorded in
docs/DATA-SOURCES.md and per file where relevant. Nothing in the corpus is medical
advice.

Logos under public/logos/ are trademarks of their respective owners and are shown for
identification only (nominative use). Files sourced from Wikimedia Commons carry their own
licences and attribution, recorded per file in public/logos/index.json. Favicons are the
organisations' own site icons, fetched via Google's favicon service.

Portraits under public/portraits/ are photographs from Wikimedia Commons, taken only from the image
(P18) attached to the person's Wikidata item and only when the file carries a free licence (CC0,
CC BY 1.0-4.0, CC BY-SA 1.0-4.0 or public domain). Each file keeps its own licence, which is not
CC BY 4.0 unless stated; the licence, author, attribution line and Commons file page are recorded
per person in public/portraits/index.json and shown on every page that displays the image (title
attribute on the picture and a credit line on the person page). No institutional or news photographs
are copied. To request removal or a correction, open a GitHub issue.
