In this talk, Jingbo Wang (NCI) and Amir Aryani (ANDS) have presented the Neo4j queries that can help data managers to explore the connections between datasets, researchers, grants, and publications using the graph model and Research Data Switchboard. In addition, they have discussed a paper on "Graph connections made by RD-Switchboard using NCI’s metadata", presented in the Reproducible Open Science workshop in Hannover September 2016.

RD-Switchboard benefits so far…
© National Computational
Infrastructure 2015
• Identify the missing critical metadata entries;
• Identify errors in the catalogue entries;
• Provide analytical view of how research data has been
used so far (high-level of utilisation or underutilised?);
• Evaluate the impact of the datasets, researchers and
institutes;
• Encourage the usage of URI, DOI and ORCID, etc.
