Are there file format preferences?: Most datasets are available in CSV and XLSX. Geospatial datasets use SHP or GeoJSON. Some statistical data is available in JSON and XML formats.
How frequently is data updated?: Update frequency varies by dataset — some are real-time (air quality), while others are annual (GUS demographic statistics).
Can I search by institution?: Yes — use the CKAN q=organization:urzad syntax or browse datasets by institution through the web interface.
Is the API compliant with EU regulations?: Yes — the portal implements the EU Open Data Directive (PSI Directive) and INSPIRE Directive for geospatial data sharing.
