Open source
Third-party licences
Food Info stands on a lot of open-source shoulders. This page lists the components bundled into the production build, the licences that cover them, and where to find their copyright notices.
Frontend
Our Angular build emits a complete licence inventory (3rdpartylicenses.txt) generated by the Angular CLI. It contains the full notices for every npm package included in the production bundle. You can read it directly:
The licences in use are all permissive:
- MIT, Angular framework, RxJS interop, Express, most utilities.
- Apache-2.0, RxJS, a handful of supporting libraries.
- 0BSD, tslib.
- SIL Open Font License (OFL-1.1), the Inter and Fraunces font subsets, vendored via
@fontsource/*.
No GPL, AGPL, LGPL, MPL, SSPL, BSL or proprietary "no-licence" packages are bundled. If you spot one that we've missed, please tell us, see Contact.
Backend
The .NET service depends on:
- ASP.NET Core 10, MIT (Microsoft).
- Microsoft.AspNetCore.Identity.EntityFrameworkCore, MIT.
- Microsoft.AspNetCore.Authentication.Google, MIT.
- Microsoft.EntityFrameworkCore + EFCore.NamingConventions, MIT / Apache-2.0.
- Npgsql + Npgsql.EntityFrameworkCore.PostgreSQL, PostgreSQL Licence (BSD-style, permissive).
- Swashbuckle.AspNetCore, MIT.
All permissive. None impose copyleft obligations on Food Info's own source.
Data
Nutrition data is sourced from two public reference databases:
- USDA FoodData Central, fdc.nal.usda.gov. Published in the U.S. public domain.
- McCance & Widdowson's Composition of Foods Integrated Dataset (CoFID) , published by the UK Office for Health Improvement & Disparities / UK Health Security Agency under the Open Government Licence v3.0. Food Info "contains public sector information licensed under the Open Government Licence v3.0", as required by that licence.
We re-present that data with our own grouping, ranking and design, but the underlying numbers belong to USDA and OHID respectively.
Reference-intake values used to calculate %RI / %DV are the FDA's 2016 Daily Values and the EU / UK Reference Intakes (Annexes XIII A & B of Regulation 1169/2011), both of which are public reference tables, not copyrightable data.
