[Koha] MARC frameworks - sharing

[Elaine Bradtke]

I'm about to put together some rather specialized frameworks that may be
useful for other collections that have historical or archival sound
recordings in digital formats (we have both). Even basing it on the existing
one for audio cassettes and CDs is taking a bit of time.  It seems like it
would be a good idea to set up a repository of useful frameworks that we
could share.
