Your research data are any objects, whether physical or digital, that you create in the course of your research. Proper research data management (RDM) is vital to ensure longevity, make data available for future reuse, and to comply with funder and institutional policies.
The RDM team here at UoW has information on their webpages covering the planning of data management, gathering and working with data, sharing and reusing, as well as archiving. You should make yourself familiar with the university's Research Data Management Policy.
Jisc has built an RDM Toolkit for Researchers, featuring resource guides and links to training videos.
It is a great place to get started for those new to managing research data.
