This addresses the problem that a particular author's contributions to the scientific literature or publications in the humanities can be hard to recognize as most personal names are not unique, they can change (such as with marriage), have cultural differences in name order, contain inconsistent use of first - name abbreviations and employ different writing systems . It provides a persistent identity for humans, similar to that created for content - related entities on digital networks by digital object identifiers (DOIs). </P>
