Authorship

An authorship relation connects a person to a research product they have authored. It carries information about the author's role in the work, their position in the author list, whether they are the corresponding author, and the affiliations they declared at the time of publication. For details on how this relation is generated in the Graph workflow, see Step 3 in the Person and relations methodology.
