RDF and similar tech does suffer from documentation that is hard to digest, and hard to see how they combine.

The semantic stack is fundamentally about how you share data, integrate it etc Taxi seems to try and differentiate itself by describing data better (I've not looked at it deeply just some of the comments here describing it) for interchange. Also the restrictions on data, i.e. its shape (mush have property x) is what Shacl supports, which is also declarative in RDF.

There are a bunch of tools, extensions and what not out there for all this, most of which isn't grasped by average devs (don't mean that in a bad way).

There is https://www.hydra-cg.com in this space, which I've not even quite understood!

Also https://comunica.dev

I think the goals of these go beyond basic API specification and client generation.
