Some questions about HYDRA

Greetings fellow HYDRA heads,

I have a couple of HYDRA (and JSON-LD) related questions:

1. How essential is the entrypoint to a HYDRA api? Why isn't a dedicated
EntryPoint class defined? Could the ApiDocumentation function as the
entrypoint resource (I doesn't seem so, but figured I'd ask)?

2. What is the functional difference between the @context and the @type
keywords? More specifically, why would you opt to use @type instead of or
in addition to @context, when it seems that you can achieve sufficient
descriptiveness with the use of just @context and sub/scoped contexts? I've
read through https://json-ld.org/spec/latest/json-ld/#the-context and
https://json-ld.org/spec/latest/json-ld/#specifying-the-type, but it is not
clear what the use of one is accomplishing in contrast to the other.

Thank you all,

Kris
