- | ## Identifier maps The schema may designate certain fields as having a `mapSubject`. If the value of the field is a JSON object, it must be transformed into an array of JSON objects. Each key-value pair from the source JSON object is a list item, each list item must be a JSON objects, and the value of the key is assigned to the field specified by `mapSubject`. Fields which have `mapSubject` specified may also supply a `mapPredicate`. If the value of a map item is not a JSON object, the item is transformed to a JSON object with the key assigned to the field specified by `mapSubject` and the value assigned to the field specified by `mapPredicate`. ### Identifier map example Given the following schema: ``` - $include: map_res_schema.yml - | ``` Process the following example: ``` - $include: map_res_src.yml - | ``` This becomes: ``` - $include: map_res_proc.yml - | ```
