This projects offers a domain model for the CISAC CWR standard v2.1 to be used on Python applications, along a series of parsing which allow transformations between the model and various data structures.
CWR stands for Common Works Registration, and it is a common or standard format for the registration and revision of musical works, used by publishers and performing rights societies as a way to exchange musical works data.
While the CWR standard has been created by CISAC this library has been developed by WESO independently, with help from BMAT.
Features
Model for CWR files
Configurable parser from transforming a CWR file into the model classes (including Pyparsing grammar)
Parsers for for model-JSON transformations
Documentation
Check the latest docs for the most current version of the documentation.
They are generated with the help of Sphinx. The source files for this are stored in the docs folder.
Usage
The application has been coded in Python. Dependencies are taken care with the use of pip, and an included makefile helps building the project.
Prerequisites
The project has been tested in the following versions of the interpreter:
Python 3.4
Python 3.5
Python 3.6
All other dependencies are indicated on the requirements.txt file. The included makefile can install them with the command:
$ make requirements
Among them, the most important is the Pyparsing library, which is used to create the CWR file parser.
Installing
The project includes a setup.py file and a makefile allowing direct installation of the library.
This can be done with the following command:
$ make install
Additionally, the project is offered as a Pypi package, and can be installed through pip:
$ pip install cwr-api
Making use of the parser
Once the project is installed it can be used in a similar way to this (using Python 2.7):
import codecs
import os
from cwr.parser.decoder.file import default_file_decoder
from cwr.parser.encoder.cwrjson import JSONEncoder
if __name__ == '__main__':
print('File to JSON test')
path = raw_input(
'Please enter the full path to a CWR file (e.g. c:/documents/file.cwr): ')
output = raw_input(
'Please enter the full path to the file where the results will be stored: ')
print('\n')
print('Reading file %s' % path)
print('Storing output on %s' % output)
print('\n')
decoder = default_file_decoder()
data = {}
data['filename'] = os.path.basename(path)
data['contents'] = codecs.open(path, 'r', 'latin-1').read()
data = decoder.decode(data)
encoder = JSONEncoder()
result = encoder.encode(data)
output = codecs.open(output, 'w', 'latin-1')
output.write(result)
Collaborate
The project is still under ongoing development, and any help will be well received.
There are two ways to help: reporting errors and asking for extensions through the issues management, or forking the repository and extending the project.
Issues management
Issues are managed at the GitHub project issues page.
Everybody is allowed to report bugs or ask for features.
Getting the code
