Datasets are collections of raw data. Data gathered for a specific purpose can be used many times over, from different angles, and to satisfy different research questions - this is particularly true when a data set is shared. Researchers and public bodies are increasingly choosing to share the data they gather in accordance with "FAIR principles", making it: Findable, Accessible, Interoperable, and Reusable. This FAIR data policy has several clear benefits, not least the fostering of new relationships and collaboration among researchers (Popkin, 2019).
Below are some sites dedicated to the sharing of open data sets. It's not an exhaustive list, and the number and breadth of data sets will surely increase as more and more researchers choose to share their data.
Irish National Open Data Portal
Datasets made open for reuse by some 111 publishers, including: Central Statistics Office, city councils, government departments, Environmental Protection Agency, EuroStat, Fáilte Ireland, Geological Survey of Ireland, Health and Safety Authority, Heritage Council, Met Éireann, National Transport Authority, Office of Public Works, Ordnance Survey Ireland, Revenue Commissioners, Road Safety Authority, TUSLA, and more. New datasets and publishers are being added all the time.
