Ogg MIDI proposal
...likely
there will be very few pages of MIDI data.
Each MIDI Ogg packet will contain rougly 512 bytes aligned to MIDI event
boundaries. This means approximately 8 MIDI packets will normally be place
in an Ogg page.
MIDI header packet format
-------------------------
The MIDI header will be:
'OggMIDI\000'
version (1 byte) - this is the OggMIDI version supported, starts from 0
time format (1 byte) - this is the time format, 1 for ticks per
quarternote; 24,25,29,30 for SMTPE time
timebase (2 bytes) - subdivisions per SMTPE frame or ticks per quarternote
MIDI packet format

There is definitely a spec for doing this: http://wiki.xiph.org/OggMIDI
Granted, this spec is 11 years old, so may not reflect any changes in
thinking re ogg mappings, etc that have occured since then, but it looks
pretty thought out.
I do also recall some software being written a long time back, like 2000
or 2001, for doing this sort of thing. I think it was wri...

Is everything correct? Did I miss a codec?

I noticed the following Subversion commit today:

Updated doc to reflect current proposal...
Not as much a proposal at this point actually; this is the way I'm now
implementing it. Although we're still in the 'RFC'/'look for horrible
lossage' stage, this is close to being
