I agree completely. We need a way to facilitate interoperability without requiring normal humans to know/care about bytes on a disk in some hierarchy (directory tree) where, frankly, your hierarchy WILL eventually be wrong. Remember back in the old days, organizing your music files into a directory hierarchy- often organized by band? Then, inevitably, two bands you listen to release a song where they collaborated. Now your system is fucked- where do you put that song? It's why "tagging" things became a thing (emails, magical "Pictures" directory in your OS's file manager, etc). There has to be some kind of extension to the idea of "tags"...
