I’m looking for a way to capture the age rating (i.e. T+, Parental Advisory, Mature, etc). Curious to see how others are doing it and what categories you use?
For movies and games, the audience rating is indeed “a thing” and therefore our movie and game apps fully support it as a database field.
Not sure for comics, never seen that request earlier.
I use a tag for ‘naughty’ covers 
Maybe this can be that request 
I was cataloging the latest issues of Wolverine and this particular story arc has “Parental Advisory” whereas previously it was T+. That got me to thinking about the other Vertigo and Image titles that were also either Mature or Parental Advisory. And of course those Sex Criminal variants
