Open data is defined as data that can be used and redistributed by anyone with minimal or no restrictions. A design science research methodology was applied to the development of an open data portal for theMinistry of Health Sri Lanka (MoH) to share national datasets. Following requirement gathering and literature review, the open data portal was developed using open-source software and implemented at the MoH Sri Lanka. Fifty datasets obtained from the MoH were categorised and published in the open data portal. However, several barriers cast doubt on the long-term feasibility of the open data portal project.
