Governments are increasingly embracing openness and transparency by making more data publicly available through open data portals and catalogues. However, individual catalogues can be limited in scope and interoperability. The document discusses enabling interoperability across government data catalogues by developing a standardized reference structure and vocabulary that allows catalogues to be geographically overlapping, thematically complementary, and support distributed publishing. The authors analyzed seven existing catalogues and published three in a new interoperable format using their reference model, which has now been adopted by some national data portals.
