Common Works Registration 3.0

A series of articles about CWR 3.0. They are not a replacement for official documentation by SPF/CISAC.


For a very long time, there was a single Common Works Registration version in use - 2.1. Version 2.2, introduced as an interim version that supposedly “would solve some urgent issues” was, in reality, a dead end. But, now (July 2019), CWR 3.0 specs are out. In the following articles, I will be covering CWR 3.0 from various angles, as I work on updating various tools and services that use CWR.
