This document summarizes Laurel Haak's presentation on ORCID (Open Researcher and Contributor ID) at the CAUL/ANDS Roundtable in Canberra on July 29, 2014. ORCID aims to solve the problem of name ambiguity and lack of unique identifiers for researchers by providing a free, global registry of unique identifiers for individuals. Over 800,000 identifiers have been issued since 2012. ORCID works with various stakeholders like publishers, funders, and universities to integrate ORCID IDs and enable interoperability between systems through its APIs. The presentation provides examples of how various organizations are integrating ORCID into their workflows and systems.
