This is a Python library for parsing, validation and generation of CWR 2.1 and 2.2 files. It extends the functionality of Music Metadata - EDI.

Common Works Registration (CWR) is a protocol and data format for the registration of musical works in collecting societies world-wide. You can find out much more about it on developer's website or in the videos below.

Currently the library can parse CWR 2.x files, with file-, group-, field-, record- and most of transaction-level validation. From there, it can be converted to HTML (visual validation), JSON, etc. There is a DEMO. The code for the demo is released as open source.

Although this is a CWR 2.x library, the terminology is from CWR 3.x, and the output structure is the same for CWR 2.1, 2.2, 3.0 and upcoming 3.1 versions.

This library has not yet been released as open source. The schedule depends on sponsors, feel free to become one!
