What features actually belong in the parent profile of a Blu-Ray 3D combo pack?

Take for example The Avengers, UPC#786936819670

The parent profile has many features checked, including featurettes, commentary, deleted scenes and others.

But the back cover shows that the 3D disc appears to have no features. That those features actually appear on the blu-ray child profile.

So in the case of a Blu-Ray 3D, Blu-Ray, DVD Combo Pack what features should be attached to the parent profile?

I think that if the Blu-Ray 3D is the main profile disc and it has no features that the parent profile should reflect that an no check boxes should be checked that belong to other discs in the pack.

Okay, but doesn't that make it appear that the main disc (in this case the 3D disc) has features that it doesn't actually have.

Another example is a few MGM Blu-Ray/DVD combo packs where the dvd has more features than the Blu-Ray does.

So does that also apply to Blu-Ray/DVD combo packs too?

Yes, but think of how it looks the other way around. Those who choose to list this set without the optional child profile(s), would see a profile without any features, while the set actually *does* contain featurettes, commentary, deleted scenes and others. Just not on the first disc. But as all discs are also listed in the "Discs" section, the features are also compiled from all discs.

Yes. There as well, the parent should list *all* features, including ones that only appear on the DVD disc - again because the DVD child profile is optional. Just like the parent included all media types, and lists all the discs.

Wouldn't that mean that in a 3D blu-ray, blu-ray and dvd combo pack that the 3d disc is the main media type?

I would say so, yes. That doesn't change anything about the features, though. Again, in these cases child profiles are optional, so all data must be handled in the parent. So we list all media types in the parent, we list all the discs in the "Discs" section, and we include all the features found on the entire set.

Box Sets contain more than one movie. Combo packs contain the same movie on different media. So they are not really comparable. I think they are only listed in the box set section because there is not really a better place for them in the rules.

This. It's there as a warning, reminding us that a combo pack is not a box set, and is therefore not handled the same way.

pretend that the child profiles don't exist, and you're profiling the entire contents of the release as a unit.

This.

Not that it affects me, but if one wants an accurate profile for the 3D disc than one would have to create a local only profile for that disc to accurately reflect what's contained on that disc, right?

Yeah, e.g. on BD/DVD-Combos I try to clean the BD-parent up, because I don't like how they look iff according to the rules.
I would have preferred a clean Box-Set rule for combos, but Ken decided otherwise.

Invelos, is this really how you want your online database to work? "Keep it local" for just about everything people would like to have?
