"ORCID provides a persistent digital identifier that distinguishes you from every other researcher and, through integration in key research workflows such as manuscript and grant submission, supports automated linkages between you and your professional activities ensuring that your work is recognized."
While becoming the international standard identifier for scholars, it is an open, non-profit, community-driven effort to create and maintain a registry of unique researcher identifiers and a method of linking research activities and outputs to them. It is interdisciplinary and not dependent on a particular publishing platform.
