ORCID in Wikipedia = three uses

ORCID in Wikipedia 1. For article Subjects

VIAF Mass import to English Wikipedia, by “bot” Errors are being logged Mass conversion to Wikidata, by bot (just completed) Ongoing liaison with VIAF team at OCLC VIAF recently changed from linking to the English Wikipedia to linking to Wikidata & thus all Wikipedias

VIAF

In summary… Wikidata stores many types of authority control IDs IDs are then imported to Wikipedia articles in many languages Wikidata can be used to link IDs in two – or more – authority control systems Wikidata is copyright-free, linked, open data Wikidata welcomes your input Get an ORCID iD!
