1. What is DR-NTU (Data)?

DR-NTU (Data) [https://researchdata.ntu.edu.sg] is the institutional 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.

For more information about Dataverse, please see Dataverse Project

2. What is final research data?

The final dataset is a collection of final version of data that exits during the last stage in the data lifecycle in which all re-workings and manipulations of the data by the researcher have ceased. (Source: NTU Research Data Policy Section 4.C.)
