I only prefer "Collective" over "Organization" because it seems to work better for describing a band, for instance - a collective can be a collective of musicians or a collective of businessmen in a company, while organization is more suited to the latter.
It's sort of like NES
but it has diverged a bit. We don't have any documentation of the exact system we've implemented (yet).
The difference here for me is that lost movies were at one point publicly available, so recording them has historical usefulness. My problem with including private videos is that it pollutes the publicly useful data, potentially making it less useful. For example, if a user searches through the database for a certain phrase, and there are a large number of private videos with titles containing the phrase, the useful public metadata might not be found. And metadata for private content will be of lower quality than the public metadata, since editors won't be collaborating on improving it. If those matters were solved or made irrelevant, I wouldn't be against storing private metadata.
We definitely want covers in BB, but the process of getting it set up has stalled a little (@reosarevok - let's discuss that soon!). I guess VB might also want promotional posters (although BB could use them too), promotional stills, perhaps any bonus concept art included in the release? The big obstacle to getting all of this done is communicating what we want with the internet archive and getting stuff set up there.
