* equal first authors
+ joint front middle authors
^ equivalent middle middle authors
• totally cool back middle authors
# equally senior senior authors
@davidschlangen I'm still waiting to see a paper that does something like: *, +, and % indicate three equivalence classes of contribution; * it's the primary equivalence class, the others are unordered with respect to each other
@csgordon “Let the set of authors be A. The relation R specifies the contribution lattice over the partition P of A, where P and R are defined as follows: […] R is to be interpreted so as to assign “has really done a lot” to the supremum, and “is really important” to the infimum, and “was also involved” to anything in between, with R indicating degree of involvement.”
