API documentation techniques

Hey everyone!

I am researching API documentation toolings for linked data APIs.

The main goal is to have *Swagger*-like experience tailored for rdf. I know
*Hydra* looks to be heading in that direction but it seems they have very
little momentum.

I am particularly interested in solving the body validation problem. Has
someone implemented a *SHACL* based validation for this purpose?

All thoughts are welcome

Yours
Kaspar
