Introduction¶
Music Metadata Management¶
DMP (Django-Music-Publisher) is free, open-source software for managing music metadata:
- musical works and recordings (with audio files),
- writers, artists and labels (with photos/logos),
- releases/albums (with cover art), and
- music libraries.

Common Works Registration (CWR)¶
It implements CWR protocol for batch registration of musical works with Collective Management Organizations (CMOs) and Digital Service Providers (DSPs).

CMO->>Publisher: CWR ACK 1 (Technical validation)
CMO->>Publisher: CWR ACK 2 (Registration status + CMO work ID + ISWC)
Note over Publisher,CMO: Royalties
CMO->>Publisher: Royalty Statement (CMO work ID + royalty amount)
Royalty Management¶
Simple royalty processing calculations can split received royalties among controlled writers and calculate publisher fees.
Incoming data is accepted as a CSV file. If registrations are done using CWR, work matching is fully automatic. Output is a similar CSV file with additional rows and columns.

CMO/DSP->>Publisher DMP: Incoming Royalty Statement (CSV)
Publisher DMP->>Publisher Excel: Augmented royalty information
Publisher Excel->>Writer: Outgoing Royalty Statement
Publisher Excel->>Accounting: Accounting data
This file can be then imported into Excel and turned into individual outgoing statements and accounting data using pivot tables. This process can be automated using Excel templates and simple scripts.
