It is now possible to use Authority Control identifiers (such as VIAF, ORCID, etc.) for taxon authors on Wikispecies.
It is also possible for editors to put their own ORCID (or other Authority Control) identifier on their user page.
For details of how to do this, and examples, please see:
https://species.wikimedia.org/wiki/Template:Authority_control
ORCID is an open identifier for researchers and other contributors to academic literature. Background information on ORCID for Wikimedia users is at:
