1. What is DR-NTU (Data)?

DR-NTU (Data) [https://researchdata.ntu.edu.sg] is the institutional open research data repository for NTU supported by the Library and CITS. The repository is built on an open-source web application called Dataverse to share, preserve, cite, explore, and analyze research data.

DR-NTU (Data) is the local instance of Dataverse, a software installation which hosts multiple dataverses. Each dataverse contains datasets, and each dataset contains descriptive metadata and data files (including documentation and code that accompany the data). As an organizing method, dataverses may also contain other dataverses.
