In order to extend the adserver AdServer interface functionality, you can add key values in the objects Ad Spec, Ad Type, and Placement (not supported after 2.112). 

...

Manual Syntax Examples:

• gender!=male

• age=18,19,20,21 and gender=male

• age!=0 or (gender=female and (cat=sport OR cat2="value with spaces") and location=de,at,ch,fr,nl)

...

With version 2.112 we changed the logic of the predefined keys and values on Ad Spec and Ad Type to the new format based on AdServer IDs: 4.3.4.4 Key-Value / Audience (AdServer) Targeting

This will allow us to provide a more stable and flexible solution for you and also enables this feature for the AdServers Xandr and Freewheel. If you were using the old format for Google Ad Manager, your existing products will continue to work, but the /wiki/spaces/SO/pages/126422313 won't support the creation of new Key Values in the old format will not be supported. Please see the chapter below on detailed migration steps.

This results in the following changes to the feature:

1.) Keys & Values will be saved in a JSON string

Instead of the old format (e.g. Key = Value) The key values will now be entered in the form of a JSON string into the field:

{"KeyValue":{"type":"List","logic":"||","valL":[{"type":"List","logic":"&&","valL":[{"type":"List","logic":"==","valL":[{"type":"Id","valS":"a09A0000010it2KIAQ"},{"type":"List","logic":"||","valL":[{"type":"Id","valS":"a09A0000010it3yIAA"},{"type":"Id","valS":"a09A0000010it4KIAQ"},{"type":"Id","valS":"a09A0000010it4MIAQ"}]}]}]}]}}

As this refers to IDs instead of names, the system makes it easier to handle keys and values with special characters in their names.

...

1. Enable the usage of 4.3.4.4 Key-Value / Audience (AdServer) Targeting: All you need to do is display the field AdServer Targeting field into in your Media Configuration

2. Enable the new Key-Value Generator. Make sure that the lightning action for the Key-Value generator is included in your Page Layouts: 

   

3. Turn your existing data into the new format: To do so, simply open your Ad Spec or Ad Type with the Key Value Generator. It will automatically be turned into the new format and you can simply click save, to change your products:

   

Additional Note - Key-Value connecting logic for Xandr

When you are using the fixed Key Values for Xandr, it's possible to create a targeting set, which can not be edited in the console UI of Xandr. This will be displayed as follows:
