I have found this unofficial style guide:

Could please someone tell me, if a valid track number also can be a roman numeral?


I don’t see why not. It is on the scans as Roman numerals. I wouldn’t use them if they weren’t though.

It’s hardly the most unusual kind of track numbering. :wink:


I don’t see why not either.

Note: you shouldn’t use the unicode roman numeral table. Its use is discouraged in the unicode spec.

Unicode roman numerals: Is there an official stance?

How do you translate the Roman numeral IV (4) to the ID3tag “track number”?
The official description says:

TRCK: The ‘Track number/Position in set’ frame is a numeric
string containing the order number of the audio-file on its original
recording. This may be extended with a “/” character and a numeric
string containing the total numer of tracks/elements on the original
recording. E.g. “4/9”.

Should this be 4/9 for the asked example?
And what about @mfmeulenbelt’s example with the W O R L D P E A C E !?


We have two different concepts (number and position or something like that). Position is always 1-n and is what Picard uses by default for track numbering IIRC.
