An object is a container of values.

A map implements converts map semantics into an object.

This is a very loose implementation of the JSON pointer schema as defined here: https://tools.ietf.org/html/rfc6901 Pointers can refer to elements within a document and can contain a reference to the document itself.

A ref is a array-like, string representation of a field within a document.
