Exposing API schema

[isBatak]

How hard would it be to expose resource schemas via API so the frontend can build a CLI tool for building Resource definitions used in frontend clients?

It shouldn't be a problem. We could add something like a _schema endpoint, following on the initial conventions defined in json-api/json-api#1447.

This is cool... I saw describedby in 1.1 documentation but haven't realized it's for exposing schema definitions.
I'll have it in mind.
