Under question 2.2 “How does MusicBrainz use ID3 tags? What about for Ogg files?” is a link to “Picard tag mapping table,” (https://picard.musicbrainz.org/docs/mappings/) which leads to a “Page not found” error.
I believe the correct link is https://picard-docs.musicbrainz.org/en/appendices/tag_mapping.html?highlight=mapping, but that should be verified.
