IAB published this month a draft for public discussion with a nomenclature for data. The document is titled “OpenData 1.0: Standard Nomenclature for Campaign Performance Data,” and was created “due to a lack of standard nomenclature.” An IAB Tech Lab’s OpenData Task Force was formed with the “primary focus of alleviating issues that have challenged marketers in the data report merging process.”
The lack of a nomenclature “impacts companies who receive data reports from sources such as ad tech vendors, data management platforms, and other partners. For example, an agency or a publisher may receive reports (delivered in excel format or via API connections) from partners that have varied header field names. The process of merging these reports may be manual and tedious, due to the lack of common field names,” explains IAB.

Here the nomenclature version 1.0:
A unit of media trafficking that most closely corresponds to a traditional I/O line item. Flights have a predicted number of impressions as well as an impression goal, and start and end dates, additional trafficking settings, and ad tags.
Explicit domain or application.
This object describes the publisher of the media in which the ad will be displayed. The publisher is typically the seller in an OpenRTB transaction.
Corresponds to the actual placement on a publisher site or app.
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.
PO could be parent to multiple authorizations.
Campaign maps to Advertiser, There will be different campaigns under one strategy.
Campaign Parent, may function as unique billing bucket.
Company object may have parent relationship with “Advertiser” OR Any 3rd party that may own a relationship with Advertiser.
Attribution object; Organization owns information coming through a field. (Use case of audience data id associated with the DMP organization type). The organization must have at least one associated business object (agency, brand, division, advertiser, publisher, user, etc). *Alternate nomenclature: “Data type.” Implementation notes: This object is expected to be used internally within each proprietary system, and only optionally shared externally.
The human user of a device. Defined in OpenRTB.
The code that renders the creative within the publisher placement.
The creative ad in a different size or ad unit.
Landing Page URL
Click through URL, associated with other data to give context. Could be a URL or an entity in a system.

Anonymized ID (User ID)
A privacy-encoded identifier associated with an end consumer, the viewer of the content. Electronic client IDs. May be used in conjunction with “Target” business
object for targeting purposes. The expectation is that this ID is anonymized. Businesses should have their own policy contracts in place to be certain of PII-related policy adherence.
