RESUMO
In the era of government 3.0, the availability of open government-owned public data and data sharing with the private sector are important. We surveyed the status of public data openness in the healthcare domain and of compliance with the standard open data format based on the “5 stars of linked data” model. We examined healthcare data on the Open Data Portal (https://www.data.go.kr). We also surveyed data on the websites of the public institutions and state administrative agencies that provided healthcare data on the Portal. In terms of data on the Portal, all public institutions except the National Medical Center, the Korea Institute of Science and Technology Information, and the Korea Environment Corporation were found to have provided data in the 3-stars format corresponding to the Public Data Open Standard Maintenance Guide. All data provided by state administrative agencies met the 3-stars format. Only 2 institutions (the Health Insurance Review & Assessment Service and the Korea Health Industry Development Institute) released data in the 3-stars format on their websites. Among the major state administrative agencies providing data on the Portal, none released data in the 3-stars format on their websites. Government-owned data should be provided in a standard format both on the Open Data Portal and on data-holders' websites to facilitate communication and collaboration. Considering the huge potential of linked healthcare data from a single national health insurance system, providing open data in compliance with the standard open format will promote the opening and sharing of public data.
