Links to human-readable specifications

[tpluscode]

I would be nice to have links to the actual pages of the vocabularies.

Not sure how much of it can be extracted from the triples. Might have to add those links manually in the overrides?

This is a good idea. I think we would have to add that manually for most of the vocabs. There is really no clear pattern, at least none that I found so far. So we could support https://schema.org/url as pointer to the original vocab and call is Web page or alike.
