Yes, true, but I think of XML more as a Web technology requiring a complex
parsing engine. I'm not a Web programmer so my thoughts on XML are probably
somewhat broken.
Another comment was made about the difference between what's actually on the
media versus what the CPU actually sees. We would thus need to capture the
raw data stream from the "heads" side of the controller in order to
regenerate a usable original media from the metafile.
For emulator use, we can grind this metafile through a translation program
to get the bytestream. OR, the metafile could contain both types of data
(using the container file and metadirectory idea from earlier).
What we really need is PDF for magnetic media :-)

I was thinking similarly to you but not using XML metadata:
;Hardware descriptor
MFGR
MACHINE
SUBTYPE
DRIVETYPE (this of course defines what follows)
;for floppy
DRIVESIZE
ENCODING
TRACKS
SECTORS
SECTSIZE
;HexData
; Each record or group of records contains the related media data. The
address record would be used for encoding the metadata
00TTSSHH: (00-track-sector-head)
I looked to Intel Hex (or Motorola) because it had built-in CRC facilities
and it was human-readable ASCII. The drive and machine description could
be
encoded in special MOT records probably.
I like the XML style because it's more explicit; more human-readable.
XML is more a more "current" technology but
I was trying to keep with the
platform neutrality by sticking to text-only and not assuming the use of
any
other technology like XML.
XML is platform neutral because it's basically ASCII, right?
