Tag Mapping

From Hydrogenaudio Knowledgebase
Revision as of 17:33, 8 September 2021 by Beardgoggles (talk | contribs)

Introduction

This page attempts to document a useful mapping between the tagging schemes used on various (audio) file formats. Hopefully this will help those developers trying to transcode or move audio data around and wish to retain their tags. It is hopefully also of use to developers that read and write metadata from audio files.

Please note that this page is about mapping tags to each other, it does not detail nor dictate the actual way the metadata is stored nor any limitations (or lack thereof). This is way beyond the scope of this page.

The terms metadata/tag/field may be used intermittently on this page to mean the same thing. Also note that this page might not be complete, and may never will be.

Please do not rely on the content being accurate.

Organization

The below tables are organized into categories of data, and within each category the ordering is roughly as follows:

1. tags that apply to a wider range of data (e.g. a whole CD) come before tags that apply to a narrower range of data (e.g. one track).

2. tags are sorted alphabetically where this is relevant.

3. tags that are more widely supported come before tags that are less widely supported.

4. tags that fall into smaller unnamed sub-categories are grouped together.

5. tags that appear very similar but which have not yet been mapped are listed next to each other.

This document will not deal with approaches to tagging, except where certain approaches to tagging are required to make mapping work.

Additional Information

Ape pictures

APEv2 stores each picture type with a different key according to the ID3v2 [4] APIC frame's picture type. This is unlike other formats, ID3v2 for example, where all pictures are under a single ID ("APIC") and identified by a picture type.

Issues

Due to the re-purposing of ID3v2's TPE2 as Album Artist, we have no field to store the name of the Orchestra, yet we have a dedicated field for the Conductor.

Author / Writer / Lyricist clash through ID3v2 (worse if artist=author or title=author!)

Performers vs involved people vs musicians. All musicians are involved people; not all involved people are necessarily musicians!

Dates - some are specific (recorded/released/tagged) others are just a non-specific date.

Mp3tag

Mp3tag contains some mappings in its initial configuration:

Tag Source Target
VorbisComment DATE YEAR
VorbisComment ORGANIZATION PUBLISHER
VorbisComment TRACKNUMBER TRACK

These mappings were previously internal to Mp3tag, they are now included as initial values in the "User-defined field mappings" preference, which was introduced in version 2.45.
