I usually tend to use words like these in sentences wherein there are phrases or clauses in which those words are the subject.

In all seriousness though, I mentioned JSON:API because it is a standard one can easily Google and it is a graph based data access API.

I wanted to demonstrate that it was possible for GraphQL to have been RESTful with the same ontology and mechanics.

I couldn't care less if someone created a JSON:API fork that handled relations like GraphQL, it would still be heavily preferred to GraphQL.

Also, the format for filtering in JSON:API is not defined by the spec. In other words, you can write whatever wacky query language you want.
