Enumerations
OpenRTB 2.5 enumerations are not collected separately yet
The enumeration lists of 2.5 are embedded in the spec text (Chapter 5 Enumerated Lists, PDF only) instead of being externalized to AdCOM like 2.6, so this site has no standalone enumeration data yet. Enumeration references in field descriptions (e.g. “Refer to List 5.8”) follow the official PDF; enumeration value tables are on the roadmap.
