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, e.g. T0370000024
- 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 number 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.

As of 2011-12-29 the old TIWC 6-char codes have been withdrawn.
