DMP
DMP (Django-Music-Publisher) is open-source music catalogue management software for
management of music metadata,
registration of musical works,
royalty statement processing, and
basic data distribution.
DMP will work for most small publishers world-wide, but it does not try to solve first-world problems (e.g. US PRO rules) for free. See Features and Limitations.
Based on Django web framework, DMP is primarily designed to be deployed to a cloud, but it can be installed to a personal computer. (Linux, Mac OS or Windows). See Installation for details.
