Hi! @hauschke pointed me to this a while ago and I still owe him to share what I know.

• The R project has a set of author roles, see https://r-pkgs.org/description.html#sec-description-authors-at-r and https://journal.r-project.org/articles/RJ-2012-009/
• codemeta also has different terms, look for "Person" in https://codemeta.github.io/terms/, e.g., sponsor, producer, contributor

Tagging @sdruskat as a software metadata mastermind - can you help out with a taxonomy of different contribution types for software?

Thanks @nuest for pinging me.

We're discussing software contribution role taxonomies in the Research Software Alliance Task Force "Research Software Authorship and Contribution" with the aim to build community consensus and make a recommendation about which roles to use and implement. As this is a community process, it's taking some time.

In terms of the Citation File Format, we have decided to postpone any decisions on which taxonomy to support until after the task force has completed its work, but will still introduce a free text contributors field in the meantime.

Personally, I think that All Contributors hits about the right resolution level (or "detailedness") and covers many roles already, although terminology needs to be checked (e.g., the leet-ish a11y suggests allyship (e.g., for EDIA) but expands to accessibility which may or may not be a subset of this).
