ORCID has been working with CrossRef and DataCite to enhance the interoperability of scholarly information - capturing embedded unique identifiers for researchers and their research outputs (journal articles and datasets) and supporting the improved flow of information between systems. The benefits, and potential, of these developments are really exciting. Researchers benefit from automatic updates to their personal record, systems linked to the ORCID registry can re-use the information, saving more time and effort, and other IDs and information sources can link to the new metadata. Building connections like this, to improve the flow of information through the scholarly ecosystem, is a great example of why we refer to ORCID as plumbing. IDs help make e-infrastructure for research work better.
