It depends on which box set we have:
Real Box sets (without cast/crew) should not have a genre.
Technical box sets (e.g. 3D/BD/DVD combos) contain a complete profile. Therefore they need all information including genre.

I'm trying to figure out how the rules are vague.  Anything not specifically mentioned in the Box Set section is supposed to follow the standard rules...or did I miss something?

I see problems including this data. What if the genre for each film differ? If so, how do we list the genres?

Since, with Box Sets, each film has its own profile, personally I prefer the data to be kept there.

The Box Set rules do not specifically address this issue, as it does with other data, so standard rules apply.

I see a problem with Genres and box sets.  I think the Genres should be excluded, leave it to the individual profiles...

Either way you look at it... as the rules are written... removing them from the profile is against the rules.

It is against the rules to remove them on the basis that a Box Set should not have any genre. It is not against the rules, however, to remove them if they do not represent faithfully all that is in the Box set. Better no genre than incorrect or incomplete ones.

I agree with Kathy. What sense does it make to put genres on box sets when you can only list 3 that show up in the online. I could care less "what someone thinks the box set genre is." I want to know what each individual movie is.

While I do  understand that the OP asked whether or not box sets should have genres, that is an irrelevant question when it comes to contributions.  The rules are quite clear on this subject.

The rules state:

Quote:
"For the main Box-set profile, add the individual profiles via "Box set" button. The following Clarifications to the standard Rules need to be used:"

"In addition to the above, the following are not included on the box set profile: Subtitles, Audio & Disc Features. List them with the individual profiles."

Genre is not one of the clarification / adjustments to the rules, nor is it specifically excluded, so you follow the standard rule for genres which state:

Quote:
"Genres are often a matter of personal interpretation, which can differ among users. If your personal preference for Genre differs from the main database, you can store the information you prefer in your local database and lock the Genre field from further updates. Do not make contributions that only change or re-order Genres, unless the existing Genre list is blatantly incorrect."

Based on Pete's description, the genres are not blatantly incorrect, so we are left with personal preference which the rules specifically state that you can keep them local and lock the genre field.

Rather than change the online, everyone that believes genres shouldn't be in a box set profile should follow that advice.  JMHO

I say it's vague because the rules don't actually say that anything not mentioned in the box rules follow the standard rules. It lists some things that should be included and some things that shouldn't and genres aren't mentioned either way.
