So what is required is a metadata repository listing all recordings ever
made and then listings of where the masters and any copies exist (within
reason) It could be set up along the lines of the Wikipedia model, where
"Members", continually add to the listings.. We would also need to know
about original releases, re-releases and so on. Unfortunately, one of the
challenges is that humans never tend to consider the long term. We are too
busy worrying about tomorrow, and the subsequent bottom line.
