Common Work Registration

from Wikipedia, the free encyclopedia

Common Works Registration ( CWR ) is a common format (or standard format) for registering and revising musical works.

CWR provides all the data elements necessary for a publisher to register a work with a collecting society . By using a common standard for the work registration process, both publishers and collecting societies benefit from a more efficient registration system, which leads to cost and time savings.

The format was developed jointly by performance law societies and music publishers worldwide. The current CWR standards are maintained by the Confédération Internationale des Sociétés d'Auteurs et Compositeurs (CISAC).

File naming convention

From August 2006 the file naming convention of CWyynnnnsss_rrr.Vxx was adopted for use.

  • CW identifies a CWR file.
  • yy identifies the year.
  • nnnn is the sequence number assigned by the publisher.
  • sss is the sender (2 or 3-digit code for the publisher or the 3-digit code for the company).
  • rrr is the recipient (2 or 3-digit code for the publisher or the 3-digit code for the company).
  • Vxx is the CWR version.

Example: CW060001EMI_044.V21 would be the name of the first file that EMI sent to PRS in 2006.
