How many CFF files allow adherence to the software citation principles

[sdruskat]

The software citation principles define some principles for how software should be cited. Let's look at CFF files to see if they make this possible, e.g.

• [ ] providing version (principle of Specificity)
• [ ] providing a repository-code URL only (+principle Accessibility, but -principles Unique identification and Peristence)
• [ ] providing doi or identifiers/doi and others (principles Unique identification and Peristence)
• [ ] providing preferred-citation (against principle Importance (the First Principle))

Also thinking about this, where a DOI or other identifier is present:

• Does the DOI resolve correctly or is it dead?
• Does it point back to the git repository (questionable practice) or to an archived copy of the code or something else?
• What type of resource (article, software, manual, etc.) is referenced?
