internal lookup table Language dimension - Adobe Analytics

[fckyou1]

I would like to get insight into the internal lookup table that Adobe uses to determine the Language dimension (based on the Accept-Language value).

More specifically I am wondering which value (accept-language) results in the following Language values:

Dutch (Netherlands)
Dutch
English (United States)
English (United Kingdom)
Dutch (Belgium)
Polish (Poland)
English (Netherlands)
English
German (Germany)
French (France)

When is something "Dutch" and when "Dutch (Netherlands)".

And lets say I have this value: accept-language: en,nl-NL;q=0.9,nl;q=0.8,en-US;q=0.7 what Language value would be assigned to this? 

# Adobe Documentation:

"This dimension references a lookup table internal to Adobe. The lookup value is based on the Accept-Language HTTP header in image requests. "

It's an older site, but perhaps https://www.metamodpro.com/browser-language-codes can give you an idea. There is the base language (e.g. Dutch, or "nl") and the qualifier (e.g. "-be" for Belgium).

Thanks for the comment. Most language values seem to make sense (base language + highest qualifier)
