JSON:API profiles
The JSON:API enables developers to define common usage patterns with profiles. These extensions SHOULD be specified and linked in each relevant request and response.
Profiles… are a way to standardize common usages of the base specification that are simple to implement using only the parts of the specification that are reserved for implementations.
To simplify development and enhance the discoverability of data in the API, all resources MUST be specified as profiles.
Client and server developers SHOULD agree upon and understand each profile.
