I do a lot of scanning and have some very different types of packages. I agree that we certainly need some more flexible types.
- MATRIX or HUB for the inner ring of the CD or Vinyl.
- Better name for the inside of a gatefold (inner?)
- A BOX and SLEEVE type. (Makes me laugh we have OBI in there for one market, but miss a wider option)
A lot of boxsets are thrown together really cheaply. So they are just five releases with a wrapper. And this does give five Fronts. (Six when you include the wrapper itself) When you pull each item out of the box you want to know which side is the front of each item. Same with wanting to know you have five mediums.
If everything became “other” we loose the advantage of a database and allowing other projects to read this data. (I’m thinking KODI and other media centres). When there are multiple fronts, then that first front is reliably the Package front that @jesus2099 wants. Same with Back - the editors are very good at putting the front\back\spines of the BOX first in the list of artwork. And then listing each separate sub-item in order after that.
Those separate items in the box should still have their front\back\spine as they have their own front\back\spines and often are listed.
When reading some of the comments above I realise that @kellnerd is very similar in his ideas to my thoughts. That is likely due to dealing with those larger Pink Floyd boxsets where our requirements are being formed.
And no - please do not remove “liner” as a type. That is perfect for current use of a thin paper or card sleeve around the medium. As is clear from its original roots with Vinyl releases.
