Content Object

This object describes the content in which the impression will appear, which may be syndicated or nonsyndicated content. This object may be useful when syndicated content contains impressions and does
not necessarily match the publisher’s general content. The exchange might or might not have
knowledge of the page where the content is running, as a result of the syndication method. For
example might be a video impression embedded in an iframe on an unknown web property or device.

Producer Object

This object defines the producer of the content in which the ad will be shown. This is particularly useful
when the content is syndicated and may be distributed through different publishers and thus when the
producer and publisher are not necessarily the same entity.

Data Object

The data and segment objects together allow additional data about the related object (e.g., user,
content) to be specified. This data may be from multiple sources whether from the exchange itself or
third parties as specified by the id field. A bid request can mix data objects from multiple providers.
The specific data providers in use should be published by the exchange a priori to its bidders

Segment Object

Segment objects are essentially key-value pairs that convey specific units of data. The parent Data
object is a collection of such values from a given data provider. The specific segment names and value
options must be published by the exchange a priori to its bidders.
