The ASCL includes a “Preferred citation” field, with the information in it coming from authors themselves via their repos, articles, correspondence, etc. IOW, what is listed in that field is an explicit declaration of the author’s preference for citation. I’m happy to share that data with you to incorporate into CiteAs if you’d like, but the real reason I write is that we have found that there is a wide variety of ways authors want their software cited, and looking at these different explicit citation methods might help your development efforts.
