[Dataset] Categories of Datasets Offered by Current Open Data Portals

This dataset lists categories of open datasets from 40 European open data catalogs. The 40 European data catalogues were taken from four countries (France, Germany, Spain, and the United Kingdom) at a rate of 10 per country. These categories are an indicator of the topics of interests in the respective countries (back in 2016), the types of questions data publishers assume users will ask, and ultimately the types of questions citizens can ask.
