The words metadata/tag/field may be used intermittently on this page to mean the same thing. This page is also far from complete and may never be.

Standard Tags

The following tables just map tags in one format to another. Each format may have limitations, like not being able to handle UTF8 for example, or limitations as to the length of the content of a tag, some might have a non-textual tag like ID3v1 has for the Genre tag. These format limitations may or may not be mentioned on this page, so please keep that in mind.

Primary

These are the core meta-tags and supported/defined in all major tagging standards or file formats one way or another.

Tag ID3 v1/v1.1 FLAC/Vorbis/Ogg ID3 v2.3 / ID3 v2.4 APEv2 Matroska WMA
Album Album ALBUM TALB ALBUM Album WM/AlbumTitle
Artist Artist ARTIST TPE1 Artist ARTIST Author
Comment Comment DESCRIPTION COMM Comment COMMENT Description
Date Year DATE [1] TDRC [2] Year DATE_RELEASE WM/Year
Genre Genre GENRE TCON Genre GENRE WM/Genre
Title Title TITLE TIT2 Title TITLE Title
Track Album track [3] TRACKNUMBER TRCK Track TRACK TRACKNUMBER

Secondary

These meta-tags provide information that a user or software may expect. Not all formats or software may support all these tags though.

Tag ID3 v1/v1.1 FLAC/Vorbis/Ogg ID3 v2.3/v2.4 APEv2 Matroska WMA
Composer n/a PERFORMER TCOM Composer ? WM/Composer
Copyright n/a COPYRIGHT TCOP ? ? ?
Disc n/a ? TPOS ? PART_OFFSET ?
Publisher n/a ORGANIZATION TPUB Publisher LABEL WM/Publisher

Tertiary

These meta-tags while considered standard may have uneven support across various software or formats. They should otherwise be rather well specified though.

Quaternary

These meta-tags are the more rare ones. They may also be ambiguous on how the content of a tag is to be treated/parsed. Some of these may have been proprietary at some point in the past. While others may be falling into obscurity.

Non-standard Tags

Proprietary

These meta-tags are used in proprietary software, and is rarely of use outside that particular software.

Tag ID3 v1/v1.1 FLAC/Vorbis/Ogg ID3 v2.3/v2.4 APEv2 Matroska WMA
fieldname n/a ? ? ? ? ?
fieldname n/a ? ? ? ? ?

Proposed

These meta-tags are suggestions for new standards, some of these may also have previously been experimental or proprietary in nature. While they may be proposed this does not guarantee they will become standard. It just means that someone (and hopefully more than one individual) would like to see it standardized. Any tags listed here should be properly documented someplace and specified in detail.

Tag ID3 v1/v1.1 FLAC/Vorbis/Ogg ID3 v2.3/v2.4 APEv2 Matroska WMA
fieldname n/a ? ? ? ? ?
fieldname n/a ? ? ? ? ?

Experimental

These meta-tags are experimental in nature and should not be encountered normally, but in case they are they are listed here for completeness sake. These tags may appear and vanish at any time or may have their meaning or use changed at any time.

Tag ID3 v1/v1.1 FLAC/Vorbis/Ogg ID3 v2.3/v2.4 APEv2 Matroska WMA
Experimental/Custom n/a ? TXXX ? ? ?

Additional Information

Notes

  1. ISO 8601 date used/highly advised, see Vorbis Comment and ISO 8601 Wikipedia article for more.
  2. The ID3 v2.3 tags TYER & TDAT & TIME & TRDA are replaced by TDRC in ID3 v2.4, see ID3 Wikipedia article for more.
  3. Difference between ID3 v1 and v1.1 is the addition of Album track, see ID3v1 specs for more.
  4. a b c d In Matroska it matters where the tags are used. So a ReplayGain tag for Track and Album are named the same just as an example.
  5. a b c d e Some tags are only in ID3 v2.4 and there exists no equivalent in ID3 v2.3.
