Unique and Permanent Identification for Authors

ORCID (Open Research and Contributor ID)

Opción uses ORCID (Open Research and Contributor ID) which is a unique identifier whose main purpose is to provide researchers with a persistent and unambiguous author code that clearly distinguishes their scientific production and avoids confusion related to scientific authorship and the existence of matching or similar personal names. The ORCID ID of a researcher will always be the same, thus overcoming linguistic aspects, institutional affiliation and incidents related to the standardization of the scientific signature.
