Tango.info musical work code

Definition

A tango.info musical work code (TIWC) is a tango.info code that identifies a tango.info musical work.

TIWC can start with the letter T or with the letter Z.

• TIWC that start with the letter T are ISWC.
• TIWC that start with Z are not ISWC.
  • TIWC that start with the Z000 contain the SADAIC work number, e.g. the TIWC Z0000015621 contains the SADAIC work code 15621.
  • TIWC that start with Z but do not start with Z000 start with Z0999.

TIWC that start with the letter Z are not stable.

TIWC-6

As of 2011-12-29 the old TIWC 6-char codes have been withdrawn.

As of 2010 there is no plan to make these codes stable. New works are added frequently, often entering the system with

The work_codes are not stable (yet), they are sometimes changed.

Once they were planned to be 6 letter mnemonic. This needs lot of manual work. There are still many codes starting with zz and some have more than 3 numbers in it.

Current policy aims to have at least 4 letter and only 2 numbers. E.g.

• comm01 = Comme il faut

This is easier to achieve than 6 numbers : T.i editor can drag drop in Excel (automatic filling and increasing number) to get new codes. This also means number may change, if a new work gets inserted somewhere between abcd01 and abcd05 then all works after abcd05 may have a number shift.

In a good DB one would probably have a simple numeric work_id. work_id could be implemented additionally.
