Open data
This section is for public bodies that publish datasets on a site built with Exponential: managers who plan the program, site builders who set up the catalog, editors who publish datasets and developers who connect portals. It explains the terms (Open Definition, EU Open Data Directive, DCAT) with links to their official texts, and shows step by step what Exponential provides and what it does not.
