@aroslov @samtingleff - Has there been any movement on this? I'd like to be able to signal viewability without having to reinvent the wheel later.

@oldmantaiter The solution the group came up with in conversation was to use an object to associate an impression with an array of metrics, including historical viewability, CTR, etc. Metric is identified by type, reports the value of the metric, and identifies the measurement source/vendor

[oldmantaiter]

@jenniferIAB Is there any documentation on what that object structure looks like?

@oldmantaiter You can view Metric Object in section 3.2.5, pg 14 of version 2.5: https://iabtechlab.com/wp-content/uploads/2016/02/OpenRTB-API-Specification-Version-2-5-DRAFT_2016-11.pdf
