This paper demonstrates the connectivity graphs made by Research Data Switchboard (RD-Switchboard) using NCI's metadata database. Making research data connected, discoverable and reusable are some of the key enablers of the new data revolution in research. We show how the Research Data Switchboard identified the missing critical information in our database, and what improvements have been made by this system. The connections made by the RD-Switchboard demonstrated the various use of the datasets, and the network of researchers and cross-referenced publications.
