Basically we want a page like https://www.researchobject.org/ro-crate/in-use/life_monitor.html for each use case, but a bit more structured so it's easy to fill in, including links to example RO-Crates, publications, etc.

In meeting 2021-10-28 @CaroleGoble volunteered to have a go at this during BioHackathon 2021.

This task is to write down the headings expected on such a page.
