Personally I think it's achievable, providing we
stick to worrying about
floppies at the moment. Tapes, hard drives, ROM images etc. can come
later - doubtless they'd share some field names, but the structure is
sufficiently* different that it's too much to take on in a first cut.

For ROM images just a binary (or hex) file is sufficient since there is no
formatting involved.
The only information needed would be a description of what the heck it is.
If we were smart (a long stretch) we could store it as Intel hex preceded by
text descriptions (including a short description of the Intel hex format).
If the ROM is > 64K then a different hex format can be used.
ROMs and card image formats are simple enough that no great thought should
be wasted on them.
Papertapes generally come in two flavors: Text or binary, please note hex
tapes are text files. The leading and trailing nulls should be stripped but
the data should be kept the same i.e hex tapes should stay hex and not
converted to binary. I have seen people store hex data as binary which
strips load address data plus with Intel hex it is possible to load
different segments which gets lost when converted to binary.
