Hi all,

great work here! Ströer will most likely adopt the new venue-taxonomy early 2021.
Since we sell a lot of mall assets as well I´d like to ask you for a more specific feedback on the mall grandchildren:

Grandchild Category | Category Definition | Enumeration ID | String Value | Stroeer explanation
Concourse | TBC | 20501 | retail.malls.concourse | These screens are in hallways and at the escalators
Food Court | TBC | 20502 | retail.malls.food_court | These screens are in hallways at food courts
Spectacular | TBC | 20503 | retail.malls.spectacular | it this something like Ströer Digital Dream ?

I think we may have taken a stab at this in 1.1 - but logged as an issue to normalize the descriptions for 1.2
