Metatag Mapping

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.

Tag	ID3 v1/v1.1	FLAC/Vorbis/Ogg	ID3 v2.3 & v2.4	APEv2	Matroska	WMA
Title	Title	TITLE	TIT2	Title	TITLE	Title
Artist	Artist	ARTIST	TPE1	Artist	ARTIST	Author
Album	Album	ALBUM	TALB	ALBUM	Album	WM/AlbumTitle
Date	Year	DATE	TDAT / TYER	Year	DATE_RELEASE	WM/Year
Comment	Comment	DESCRIPTION	COMM	Comment	?	Description
Genre	Genre	GENRE	TCON	Genre	?	WM/Genre
Track	Album track	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.

Tertiary

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

Tag	ID3 v1/v1.1	FLAC/Vorbis/Ogg	ID3 v2.3/v2.4	APEv2	Matroska	WMA

Album Artist	n/a	?	?	?	SUBTITLE	?

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.

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

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
fieldname	n/a	?	?	?	?	?
fieldname	n/a	?	?	?	?	?
