 *  GraphQL SDL Fields
 * --------------------------------------------------------------------------
 *
 * GraphQL Objects and Interfaces represent a list of named fields,
 * each of which yield a value of a specific type. Object values should be
 * serialized as ordered maps, where the queried field names (or aliases)
 * are the keys and the result of evaluating the field is the value,
 * ordered by the order in which they appear in the query.
