TINP

Overview

TIN (Tango Info Number) is a 14-digit numeric identifier used by tango.info and others.

The TIN scheme was designed by tango.info to be used instead of the GTIN (Global Trade Item Number) scheme where tango-related items need to be covered. It covers all items that GTIN does, plus tango items that GTIN does not cover due to the GTIN authority having not assigned them numbers.

The TIN set is a superset of the used GTIN set. Specifically, it contains all used numbers in the GTIN set, and it also contains special TINs.

usage

tango.info uses TINs in URLs, e.g.

http://eng.tango.info/00724383741328
http://eng.tango.info/02480002201526

they are also needed for tagging with tools.tango.info.

Extension for addressing a specific track, perhaps called TINT

• to do
  • How to address a single side (e.g. CD) of a multiple-side album e.g a double CD album having one UPC/EAN (barcode number)
  • How to address a particular track on a Side
  • Suggestion:
    • <TIN>-<d>-<t> where <d> and <t> are variable-length side and track numbers optionally with leading zeros e.g. 02480002300120-1-01 , 02480002300120-1-20 PREFERRED
    • <TIN>-<dd>-<ttt>where d and t are successive digits of zero-padded side and track numbers e.g. 02480002300120-01-012
    • <TIN>d<d>t<t> where d and t are variable-length side and track numbers e.g. 02480002300120d1t12
    • <TIN>cd<d>t<t> where d and t are variable-length disc and track numbers e.g. 02480002300120cd1t12
      • direct understandable by humans (cd = CD), good for search engines but inappropriate for non-CD sides.

4.2.1 TPOS Part of a set

 The 'Part of a set' frame is a numeric string that describes which
 part of a set the audio came from. This frame is used if the source
 described in the "TALB" frame is divided into several mediums, e.g. a
 double CD. The value MAY be extended with a "/" character and a
 numeric string containing the total number of parts in the set. E.g.
 "1/2".

This means that the latest version of the standard for ID3 tags (the type of tags used in MP3 files) has a tag field for side number e.g. the first CD of a two-CD album would have TPOS "1/2".
