Add machine readable CONTRIBUTORS.yml file
I created a suggestion for a machine readable contributors file. I tried to find the affiliations and ORCID of the people in the CONTRIBUTORS.md file. Some data is still missing.
Using this file, I can create a DataCite XML record for archival and DOI later. I think it is readable enough to replace the CONTRIBUTORS.md file. After merging, I would create an integration on opencarp.org.
