In Danbooru's earlier years, tagging standards weren't as unified as they are now, and the various copyrights and characters of the Disney Animated Canon are casualties of those times. There is no consistency in how the Disney adaptations are tagged in relation to to the works they're based on. Snow White would have separate tags for both copyrights and characters (snow_white / snow_white_(grimm) and snow_white_and_the_seven_dwarfs / snow_white_(disney), The Little Mermaid would have separate characters under the same copyright tag (the_little_mermaid and the_little_mermaid_(andersen) / ariel_(disney)), and then you have Alice in Wonderland where there's no effort to make a separate tag for the Disney designs. And then you have inconsistencies in inconsistencies like The_Hunchback_of_Notre_Dame having esmeralda_(disney) and la_esmeralda but only one claude_frollo.
My question is this: how do we consistently tag the Disney versions from the original or other adaptations separately? Should only character tags be split, only copyright tags be split, both be split, or something more radically different? Will it be a case by case basis?
