Type hierarchy

The type hierarchy is a singleton entity that defines a mapping between concrete types and their abstract types.

Authorization notes

When modifying the type hierarchy, the caller must have resources/read permission at root level.

Please visit Authentication & authorization section to learn more about it.

Create using POST

POST /v1/type-hierarchy
  {...}

     -H "Content-Type: application/json" \

Update

This operation overrides the payload.

In order to ensure a client does not perform any changes to a resource without having had seen the previous revision of the resource, the last revision needs to be passed as a query parameter.

PUT /v1/type-hierarchy?rev={previous_rev}
  {...}

… where {previous_rev} is the last known revision number for the schema.
