Django Music Publisher - OSS
Django Music Publisher is an open source (free software) solution for original music publishers, that includes managing of data on musical works, writers, performing artists, albums, and library releases, etc. Common Works Registration files it creates will be accepted by virtually any collecting organization (including ASCAP, BMI, SESAC, HFA, MDX, PRS/MCPS, GEMA) and all major sub-publishers. This has been tested with dozens of societies already and many publishers.
It started as a pet project, a proof of concept for CWR API, but also an insight into our development process.
The current stable version is 18.11. The official documentation is here: https://django-music-publisher.readthedocs.io/en/stable/
The following articles were written before the official documentation was written, and were not included, as they are more connected to topics covered here than the topics usually associated with open source projects.
