@ankushnarula - I know. There’s nothing standard about how they choose to name those things. We’d just have to pick a few common terms and let users apply those to their movies as they see fit. Kind of like -featurette, -behindthescenes, and -deleted are somewhat generic while the actual DVD might call it a “making of documentary” or something.
Special Edition, Extended Cut/Edition, and maybe Directors Cut, seem to be the most common terms I’ve seen.
Here’s sort of what I was thinking it might look like. Could possible move the rating up to the same level as the year if necessary. Or else get IMDB to start tracking ratings per DVD release.
