Copyright file checker for Teachbooks

[BSchilperoort]

Rolf et al maintain ewatercycle.org/projects/ where BSc/MSc students demo their thesis work. Students are not always aware of image copyright, so we wanted to prevent books from building if they don't include a copyright statement.

We decided that every image file needs to be accompanied by a .yml file with metadata associated with it, for example;

• content/image.png
• content/image.png.yml

The yaml file should be formatted like;

author: "Bart Schilperoort"
license: "Apache 2.0"
date: "2025-04-16"

Then an external tool can check if every image has an appropriate copyright statement file to avoid accidental inclusion of copyright infringing images. The tool is available on https://github.com/eWaterCycle/copyright-checker

and you can see the gh actions workflow here; https://github.com/eWaterCycle/projects/actions/runs/14465398844/job/40566517048?pr=17
