cffconvert
Read CFF formatted CITATION file from a GitHub url and convert it to various formats, such as:
BibTeX
EndNote
codemeta
plain JSON
schema.org
RIS
Zenodo JSON
Supported types of GitHub URL:
https://github.com/<org>/<repo>
https://github.com/<org>/<repo>/tree/<sha>
https://github.com/<org>/<repo>/tree/<tagname>
https://github.com/<org>/<repo>/tree/<branchname>
cffconvert does not support the full CFF spec yet.
For users
Install
There are a few options:
Option 1 (preferred): install in user space.
Ensure that the user space directory ~/.local/bin/ is on the PATH.
pip3 install --user cffconvert
Option 2: use ``cffconvert`` as a Google Cloud Function
cffconvert comes with an interface for running as a Google Cloud Function. We set it up here https://bit.ly/cffconvert for the time being / as long as we have enough credits on the Google Cloud Function platform.
Really, all the Google Cloud interface does is get any supplied URL parameters, and use them as if they had been entered as command line arguments. For more detailed explanation and examples, see https://bit.ly/cffconvert.
On Google Cloud Function, set requirements.txt to:
Flask
cffconvert
and use the following as main.py:
from cffconvert.gcloud import cffconvert
def main(request):
return cffconvert(request)
Option 3 (not preferred): install in virtual environment
virtualenv -p /usr/bin/python3.5 myvenv3
source myvenv3/bin/activate
pip3 install cffconvert
Option 4 (not preferred): install globally
Note: this option needs sudo rights.
sudo -H pip3 install cffconvert
Option 5 (not preferred): install with conda
See https://stackoverflow.com/questions/41060382/using-pip-to-install-packages-to-anaconda-environment
conda install pip
pip install cffconvert
Option 6 (not preferred): install with setup.py in the user environment
python setup.py install --user
Command line interface
See cffconvert’s options:
cffconvert --help
Shows:
Usage: cffconvert [OPTIONS]
Options:
-if, --infile TEXT Path to the CITATION.cff input file.
-of, --outfile TEXT Path to the output file.
-f, --outputformat TEXT Output format: bibtex|cff|codemeta|endnote|schema.org|ris|zenodo
-u, --url TEXT URL of the repo containing the CITATION.cff (currently only github.com is supported; may
include branch name, commit sha, tag name). For example: 'https://github.com/citation-
file-format/cff-converter-python' or 'https://github.com/citation-file-format/cff-
converter-python/tree/master'
--validate Validate the CITATION.cff found at the URL or supplied through '--infile'
-ig, --ignore-suspect-keys If True, ignore any keys from CITATION.cff that are likely out of date, such as
'commit', 'date-released', 'doi', and 'version'.
--verbose Provide feedback on what was entered.
--version Print version and exit.
--help Show this message and exit.
Example usage, retrieve CITATION.cff from URL with curl, output as BibTeX:
curl https://raw.githubusercontent.com/citation-file-format/cff-converter-python/44a8ad35d94dd50a8b5924d8d26402ae0d162189/CITATION.cff > CITATION.cff
cffconvert -f bibtex
Results in:
@misc{YourReferenceHere,
author = {
Jurriaan H. Spaaks and
Tom Klaver
},
title = {cff-converter-python},
month = {1},
year = {2018},
doi = {10.5281/zenodo.1162057},
url = {https://github.com/citation-file-format/cff-converter-python}
}
Example usage, let cffconvert retrieve CITATION.cff from URL, output as codemeta.json:
cffconvert -f codemeta -u https://github.com/citation-file-format/cff-converter-python/tree/master -of codemeta.json
Contents of file codemeta.json:

Convert the contents of a local file CITATION.cff into the format used by .zenodo.json files (see Zenodo’s API docs), while ignoring any keys that are likely out of date:
cffconvert -f zenodo --ignore-suspect-keys
Results in (note absence of date-released, doi, and version):
