On Thursday February 25th project THOR organised a workshop about the use of persistent identifiers (PIDs) within the biosciences community at the European Bioinformatics Institute (EMBL-EBI) in Hinxton, UK. EMBL-EBI are a THOR partner, and the event drew a capacity crowd. Team members from ORCID EU and EBI gave presentations on the scope and future of ORCID and the use of ORCID iDs and Research Object Identifiers (ROIs) at EBI.
