Common Works Registration Tools

created by Matija Kolarić

Common Works Registration (CWR) is a protocol and data format for registration of musical works, used worldwide. Matija Kolarić is the leading author and consultant in the field.

CWR Tools is a set of free online educational tools. They can not replace good CWR-capable software, e.g. That Green Thing.

They are based on open-source code project DMP (Django-Music-Publisher), free production-ready solution used by hundreds of music publishers world-wide. They have only some features and all limitations of DMP. Use DMP if you need basic battle-tested CWR-capable music catalogue management solution.

If you need more than basic, or want professional support, That Green Thing is the obvious choice.


This is a long series about CWR, and basic concepts are explained using CWR Tools.
