This may or may not be the right topic for this, but I thought I'd ask it here after I've already tagged so much.
JoJo's Bizarre Adventure is unique, as far as I can tell, in that rather than solely separate series, as is the case of franchises such as Dragon Ball and Mobile Suit Gundam, there are tags for each of the eight story arcs thus far: Phantom Blood, Battle Tendency, Stardust Crusaders, Diamond Is Unbreakable, Vento Aureo, Stone Ocean, Steel Ball Run, and JoJolion. Whenever a character from JoJolion or, occasionally, Steel Ball Run, appeared in an image, even in a picture involving characters from different arcs, they were tagged with their respective arcs. I, thus, put it upon myself to tag some of the 27,000+ JoJo tagged images on this site.
Now, some of these are probably cut and dry, such as posts where all the characters only appear in that one story arc (example: post #1179578), but I'm less sure about characters that appear in multiple story arcs, such as Jotaro Kujo (kuujou_joutarou), where I've only tagged "diamond_is_unbreakable" on images such as post #2686988 based on his attire. Going by "what we see rather than what we know", as I've said before, I've thought about sticking to their respective outfits during that story arc, so, in the case of Dio Brando, something from the first arc, such as post #2625537 would be tagged with "phantom_blood", but something with his heart motif would be tagged with "stardust_crusaders" (post #975705).
I know I've probably made a few flubs based on these definitions, and I must admit that I'm not as familiar with some other costume changes, but I thought that's how they could be tagged. Have I done anything wrong with this tagging scheme?
