Unknown Ad Position and No-Bid Reason #35

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Referring to the reference data for Ad Position (Section 6.4) and No-Bid Reason 
(Section 6.6), each has a value 0 that means “unknown”.  However, a broad 
concept throughout OpenRTB attributes, other than block or white lists, is that 
an omitted optional attribute means “unknown”.  For this reason, other 
attributes do not have an explicit value to mean “unknown”.  For 
consistency, these should be removed as well.

The 0 = unknown value existed in the OpenRTB Mobile specification for No-Bid 
reason, but since an exchange would likely also interpret an undefined value as 
“unknown”, this should not cause a backward compatibility issue.
