An ORCID (Open Researcher and Contributor ID) is a character string that uniquely identifies a researcher. This identifier permanently refers to the same person. This makes it easier to connect publications to their authors - even if several authors share the same name or if a person transfers to another institution. More information on ORCID is provided here. Data providers in RADAR can identify the persons involved in the creation of the dataset by specifying the respective ORCIDs in the metadata record.
