Data Reuse

Data reuse is a concept that involves using research data for a research activity or purpose other than that for which it was originally intended. Data reuse can be promoted by submitting data to an appropriate repository (global or institutional) or by ensuring that data is described and comprehensible to any other researcher who may want to use it. Using appropriate metadata schemas can contribute to describing datasets so that they can be reused over time. Similarly, a data dictionary can assist in data reuse by providing detailed definitions of the data types and methodologies used in a particular study so that it can be easily understood by other researchers. Librarians can also promote data reuse through creating data catalogs to make data easily discoverable for their patrons or hosting datathons where researchers are encouraged to reuse data in innovative ways during the event.
