This does not coincide with any of the customary meanings of the word
"class" I'm familiar with. I suggest using a different word for this
thing.

That's too specific for the word "resource". The word resource is
already effectively defined by the URI spec. You need a different
term here too. This sounds like what RDDL calls a "related resource".

Again, you're overloading existing terminology. Authority is already
defined by the URI spec. I'm not sure if this definition perfectly
coincides with that or not.

Ditto.

I think answering this question requires a clearer definition of
"class". In fact, I think all the questions require a better
understanding of the thing you're calling a class.
