 * Models that don't handle requests in parallel need to implement batch format (but can give errors if they recieve more than 1 item)

+* Elements inside parameters, and inside individual input items are passed through to the model
 * All of the content in a batch (a single html request) must go to the same model
 * Any parameter settings to the model must apply to all items in batch
 * Request itself needs a unique id, (and this is different than the id of the content)
 * There is single callback URL for entire batch
 * Some items need additional input parameters per item (i.e. “language” for YAKE), Presto just passes thes through
+* All input_items must include an `id` element that can be used as a reference from the output items to match up paramters
