== Additional standards ==
==== ID3 Chapter Frame Addendum ====
ID3 Chapter (CHAP) and Table of Contents (CTOC) frames were developed in response to the growth in audio files containing more than one distinct audio program. Podcasts are an example of a single audio file which may contain multiple tracks, stories or other distinct audio entries. The addition of the CHAP and CTOC frames to an ID3 tag will provide compatible players with index information into the audio file.

Version 1.0 of the Chapter Frame Addendum was released on December 2, 2005. CTOC & CHAP frames are compatible with ID3v2.3 and ID3v2.4 tags.

==== ID3 Accessibility Addendum ====
The ID3 Accessibility Addendum makes ID3v2 metadata accessible to the visually impaired via a new Audiotext (ATXT) frame type. The addition of ATXT frames to an ID3 tag will allow compatible players to provide an audible description of the ID3 metadata.

Version 1.0 of the Accessibility Addendum was released on 20 November, 2006. ATXT frames are compatible with ID3v2.3 and ID3v2.4 tags.

== Example tags ==
A comprehensive test suite for all versions of ID3 tags are currently under development. The test suite includes both conforming tags and non-conforming tags so that both standards coformance and software robustness can be tested. Part of these will be released as example tags while the rest will be sold to cover development and running expenses. If you are interested, contact Martin Nilsson.

While waiting for the ID3v2 test suite, feel free to try the [attachment:id3v1_test_suite.tar.gz ID3v1/ID3v1.1 test suite.]
