commonmeta-py is a Python library to implement commonmeta, the metadata format for common scholarly metadata. Use commonmeta-py to convert scholarly metadata from/to a variety of metadata formats, listed below. Commonmeta-py is work in progress, the first release on PyPi (version 0.5.0) was on February 16, 2023. Up until version 0.5.1, the library was called talbot. Commonmeta-py is modelled after the briard ruby gem.


Stable version

pip (or pip3) install commonmeta-py

Dev version

pip install git+


commonmeta-py uses pytest and vcrpy for testing. To run the tests, issue one of the following commands from the root folder:

All tests:


All tests in a test file, e.g. tests/

pytest tests/

Run a specific test e.g. test_datacite_api_url in tests/

pytest tests/ -k 'test_datacite_api_url'

vcrpyrecords HTTP requests to speed up testing.
