I agree that identification is only one function, but I do not refer to rogue files at all, but the millions of releases and files on iTunes, Amazon, etc. Using iTunes as an example, the label (imprint), barcode and catalog number, assuming they actually exist, are not disclosed to the customer. Now with iTunes, we know that a barcode does exist as it nis required to. But unlike a CD, we do not know if that barcode uniquely identifies the release or not. It might be for all digital releases, be the same as the CD, or be unique to other factors⌠we do not know. To me, that does not seem like primary data to me.
If others are ok with half the primary data not being there, that is fine. To me though, it seems more appropriate to describe a release with factors that are important enough to be on the release⌠same logic as physical releases. This would be like listing releases by mastering facility, mastering artist and manufacturer of the software and hardware used. Sure, it is significant, and it surely does exist, but it is not by any means primary as it relates to regular people entering data. Such data requires more knowledge than you or I generally have for releases.
To make example of what I mean, take any 2 or 3 of these new releases, and tell me the imprint, barcode and catalog number for them, and then how that information was obtained:
Then do the same for any CD at any retailer, then you will see what I am trying to say.
I agree that the information is good to have, but for the majority of digital releases, it is just not there. I fail to understand how primary important information is N/A for the majority.
And the barcode and catalog numbers are not on the Bandcamp page either, making me wonder again how this information could be considered primary and important when I cannot even find out what it is on the release or the store front.
EDIT: An example of non music product. With a car, primary data is year, make model. From there, there is submodel , engine type, trans, etc. Although things like manufacturing plant are important to some (like me with my cars as it makes a difference), that info is not there or known to the vast majority of people. There is a difference between primary data and extra data. Do you know the color of your car? I am sure you do. But do you know the exact color code? Some cannot even get a clear answer to that from the car stickers, but just a sticker that needs to be cross referenced to get that code. That is why you will not see cars organized by color code, it is important, but not primary data.
