This is what Boost.Math is using already, it's entry is a lot longer.
As Steven pointed out, I did show a lot of what can be represented.

Sure, that's why it's tricky to add to the library metadata, I don't
want that file to be too complicated.

You won't because the site's robots.txt tells bots not access any
pages under 'development'. This was done because the test results are
expensive to serve, and web crawlers were accessing every single test
result. I could probably relax it a bit so that the plain html pages
aren't blocked.

The idea is that the contents of the metadata files would be used to
generate information that's presented to users. Currently this is just
the library list on the website, but there should be other uses for
