The platform brings together open and government sources: the election commission, parliament, the audit office, data.egov.bg, the statistics institute, the civil registry, Eurostat, the World Bank, the consumer-protection price monitor and more. This page groups them by theme, with links to the original data.
The processed data is free to reuse under a Creative Commons BY 4.0 licence, and the entire processing pipeline is open source. The ready-made JSON files are served publicly.
How the sources become site features is shown on the interactive data map; when something was refreshed — in the update log.
