The intention of this project is to standardize the list of venue types that represent Digital-Out-of-Home (DOOH) advertising screens within a programmatic OpenRTB 2.5 context. The systematization of DOOH venue types will allow for clearer targeting by media buying platforms across a spectrum of available supply-side platforms offering DOOH inventory.
The following is linked from the readme, which appears to be missing.
