Can you explain in a little more detail what you mean here? What would such a modification request look like and what's the desired outcome?
Sure! This page: https://xiph.org/vorbis/doc/v-comment.html, contains these Proposed field names:
Field names
Below is a proposed, minimal list of standard field names with a description of intended use. No single or group of field names is mandatory; a comment header may contain one, all or none of the names in this list.
TITLE. VERSION, ALBUM, TRACKNUMBER, ARTIST, etc. Perhaps TRACKCOUNT, DISKNUMBER and DISKCOUNT could be utilized. If the data is supplied by the search tools you implement, perhaps they could subsequently be stored.
Just a thought.
Mp3tag already supports the quasi-standard fields TRACKTOTAL, DISCNUMBER, and DISCTOTAL. Since VorbisComments allow for arbitrary field names, some users — depending on the other software and hardware they're using — choose TOTALTRACKS and TOTALDISCS.
If you want to make use of those fields from within Mp3tag, you can customize the Tag Panel and the File List accordingly.
See also Tag Mapping → Counts & Indexes at the Hydrogenaudio Knowledgebase and Field Names at the Xiph Wiki for details on the different fields used out in the wild.
This is getting interesting! I would need some sort of a Tag Analyzer program to see the actual tags used by the search helper tasks: Discogs, MusicBrainz; and the render apps: Apple Music, Decibel, Finder. I have tried Hex editors, but did not find all that much. Hex Fiend shows what looks like a combined field with a slash as the delimiter for a file I am looking at.
When was that wiki proposed page submitted? (Ah, 6-½ years ago. Doesn't look very good!)
Ah, something to do on a chilly Florida day! Thanks
I thought that all the previous explanation resulted in some mutual insight and understanding, but based on your answer, I'm not sure anymore.
Can you rephrase in a simple paragraph what's not yet clear and needs more explanation?
Just have to look at the tools and data at my disposal. All I heard was that what I wanted to do is WRONG, and why I wanted to do it was WRONG!
But, thanks for all YOUR help! I sincerely appreciate it.
