One thing I was wondering is, how long should a bonus movie be before it's treated as a child profile vs. a bonus short? If, for example a bonus movie is only 28 minutes long, does it warrant having a separate child profile?

This is a bit complicated, because we have no minimum length for the main feature. For example, Flicker Alley's release of George Meliès A Trip to the Moon runs only 16 minutes. So it would be acceptable as a main feature, but not as a bonus feature?

We obviously don't want child profiles for every possible bonus feature, so where do we draw the line? Is it just a matter of runtime?

I agree: this is really something that needs clarification. I have loads of "Bonus Feature Film" child profiles in my local database, some that I have contributed and have been accepted into the database, others that I haven't submitted because, depending on the definition used, they may not qualify. I don't mind keeping a number of these profiles as local, un-contributable profiles, but on the other hand, I'd be happy to upload my work to the online database.

An example that I *have* submitted: the Criterion Collection Blu-ray of Alexander Payne's 'Election' contains Alexander Payne's 49-minute UCLA thesis film 'The Passion of Martin'. I've created a "Bonus Feature Film" child profile for that, and contributed it into the database. It seems to be exactly what the "Bonus Feature Film" concept is for: a film by the same director, with it's own distinct set of cast and crew that I want to track - heck, it even has it's own set of bonus material (an introduction by the director plus a set of production notes). For myself, that's more than enough to warrant its own profile, but was I right in contributing it into the database, as it only runs for only 49 minutes? Is that long enough to qualify?

An example I *haven't* submitted (yet): the Criterion Collection Blu-ray of Mike Leigh's 'Topsy-Turvy' contains Mike Leigh's 1992 short film 'A Sense of History', written by and starring Jim Broadbent. Locally, I've created a "Bonus Feature Film" child profile for that, but as it runs for only 26 minutes, I haven't yet contributed it into the database. Should I contribute it regardless of the 26 minute running time? I do consider this short an interesting part of both Mike Leigh's and Jim Broadbent's work, and I want my database to include these credits - hence my need for that child profile. But whether to contribute it into the database or not, that's the question.

Another example I haven't submitted (yet): the UK DVD of Ed Blum's 'Scenes of a Sexual Nature' contains a lovely short by the same director, called 'The Last Post', starring Maureen Beattie, Richard Hope and Bill Thomas. There again, I've created a "Bonus Feature Film" child profile for that in my local database, but as it runs for only 8 minutes, I've kept it local for now, and haven't contributed it into the online database. But to me personally, it's not that different to Alexander Payne's 49-minute UCLA thesis film. It's a separate work by the same director as the disc's main feature, and I'd like to track it, and it's cast and crew, in my database somehow.

Again, if there's a clear set of rules that allows one and forbids the other, I'm happy to keep some of these child profiles local, but the reasoning behind creating such a child profile in my local database in the first place, is the same whether it runs for 90, 60, 50, 40 or even only 8 minutes. Either it's something significant that I want to track locally, or it's not. The running time isn't my primary concern there - I only take that in consideration when it comes to deciding to contribute it into the database or not.
